Karst terrains are often economically and socially disadvantaged areas because of their poor soil conditions and water scarcity. However, due to their special morphology and natural vegetation, several national parks were set up in karst areas. Thus, the question arises as to how well the karst national parks serve the interests of the local people...
LiDAR-based digital terrain models (DTMs) represent an advance in the investigation of small-scale geomorphological features, including dolines of karst terrains. Important issues in doline morphometry are (i) which statistical distributions best model the size distribution of doline morphometric parameters and (ii) how to characterize the volume o...
Karst areas are generally disadvantaged for traditional farming due to limited water availability, poor soils and topographic difficulties. Therefore, their population density has always been lower throughout history than in other landscapes. However , because of this fact, their natural vegetation has often remained in better condition than in oth...
Karst covers half of Croatia's territory and its most valuable natural areas are protected in eight national parks. This paper presents the results of a study on the perception of landscape values and visitor motivation in Krka NP, which is part of a larger multinational research on karst protected areas in Hungary, Slovakia, Serbia, Romania and Cr...
As part of an international project, national parks and nature parks established in karst regions are examined, with a primary focus on how local residents, visitors and influential figures (i.e., park managers, mayors) perceive the advantages and disadvantages of a specific park. The study area in this paper is the Apuseni Nature Park (Romania). T...
National parks (NPs) are the flagships of protected areas, which primarily serve the protection of nature, but are also important sites for tourism. While karst areas are generally disadvantageous in terms of traditional farming, tourism can provide new livelihoods for those who live there. Therefore, it does matter how the local people relate to t...
Units with extremely variable erodibility are typical in the succession of pyroclastic-dominated volcanic fields. Welded ignimbrites are usually resistant to erosion, thus, they often appear as positive landforms, i.e., mesas or tilted plateaus after millions of years of denudation. The Bükkalja Volcanic Area being part of the most extended foothil...
In Hungary, geographical publications already mentioned special karst objects more than half a thousand years ago. About 250 years ago, some authors explicitly dealt with limestone mountains including their spectacular large cave entrances and their famous gorges. The caves of Hungary are widely known in the world based on their natural, cultural a...
The Aggtelek Karst lies along the Hungarian–Slovakian border and it is a part of the Western Carpathian mountain range. It represents a typical example of well-developed plateau karsts in the humid temperate climate zone. Numerous surface and subsurface landforms (285 caves) were created by the intense karstification of Triassic limestones. The com...
The aim of this paper is to present the results of our research on the knowledge and awareness of visitors and residents about karst and protected areas (PAs). The research was carried out in the Tara National Park (NP)in western Serbia, which includes karst landscapes. By conducting surveys with visitors, local population, and National Park employ...
Protected areas play a key role in nature conservation but are also crucial for tourism. There are international recommendations in nature conservation (IUCN), and several international conservation conventions exist. Nevertheless, the protection categories are different in each country, and the proportion of protected areas also varies. Here we co...
The primary function of national parks (NPs) is nature conservation, but for the majority of them, tourism also plays an important role. Tourism generates significant incomes, but the benefits are often unequally distributed in space, as are the disadvantages. The karst regions are generally less developed terrains in terms of traditional livelihoo...
This paper represents a case study examining attitudes of various stakeholders about Tara National Park (NP) (Serbia), identifying also the factors that shape these attitudes. The survey method was applied to a sample of 405 respondents (197 community members and 208 visitors). In addition, 15 interviews with specific key actors (NP executives and...
According to geographic possibilism, environment does not determine socio-economic development. However, the environment sets certain constraints and limitations for development. How do natural settings influence population dynamics? In this study, we examine this question using the example of Šibenik-Knin County, which includes Krka National Park...
Ciomadul (Csomád) is the youngest volcano in the Carpathians and the Carpatho-Pannonian Region whose latest eruptions may have been witnessed by Palaeolithic people. It is the only volcano in the region where, although with little probability, future eruptions may occur. Ciomadul was a lava dome complex, and its volcanic activity included both effu...
Since the 1990s, GIS tools have provided several new possibilities in the study of karst terrains. Classical maps were gradually replaced by GIS databases and visualizations, but the analytical capabilities of GIS were also increasingly applied in karst research. Data collection has been revolutionized by continuously evolving remote sensing method...
By the example of Tara National Park (NP), we present how the geoheritage can and should be presented in a NP where the primary role is played by biology. Tara NP has a rich geoheritage, especially its karst phenomena, which include gorges (e.g. the 1000-m-deep Drina Gorge), plateaus with dolines, dry valleys, and uvalas as well as springs and trav...
Conical hills, or residual hills, are frequently mentioned landforms in the context of humid tropical karsts as they are dominant surface elements there. Residual hills are also present in temperate karsts, but generally in a less remarkable way. These landforms have not been thoroughly addressed in the literature to date, therefore the present art...
The relationship between precipitation and elevation is a well-known topic in the field of geography and meteorology. Radar-based precipitation data are often used in hydrologic models, however, they have several inaccuracies, and elevation can be one of the additional parameters that may help to improve them. Thus, our aim in this article is to fi...
Karst terrains are often protected as national parks (NP) thanks to their spectacular landforms and biologi cal features. These areas are often relatively rarely inhabited, which contributes to the preservation of all forms of natural heritage. Considering the national parks, the general (simplified) question is, whom they should serve: the protect...
Park-people relationships are crucial for the effective operation of national parks (NPs). According to this new paradigm, protected areas are increasingly considered as instruments for regional development, particularly in marginal regions. However, park-people relationships often comprise conflicts. We tried to understand park-people relationship...
Drought is a natural phenomenon that occurs when the availability of water is significantly below the
normal levels during a shorter or longer period of time and cannot meet the necessary demand. This study
focused on hydrological drought assessment of the Tisza River on four gauging stations: Vásárosnamény,
Szolnok, Szeged, and Senta for the perio...
Karst terrains have varied abiotic and biotic values. However, due to their unfavourable conditions for human settling, they are relatively sparsely populated areas. Thus, karst terrains merit and are suitable for nature protection. In this paper, partly or mostly karstic European national parks (NP) and geoparks (GP) are studied. We compiled a dat...
One of the best known places on Earth where volcanology meets archaeology and history is the volcanic island of Santorini (Thíra), Greece. It is famous for the cataclysmic Late Bronze Age (Minoan) Plinian eruption which destroyed the Minoan culture that flourished on the island. Hosting a central, flooded caldera bay and, within that, the active is...
We examine how geoconservation and geotourism can help the local development of an economically underdeveloped karst area. First, we briefly present the geoheritage of Aggtelek National Park, which largely overlaps the area of the Aggtelek Karst. The area is built up predominantly of Triassic limestones and dolomites. It is a typical temperate zone...
Our study presents the changes in the concept of the national park in space and time to Hungarian readers. It does this not only because the role of national parks in recreational activities in Hungary has been evaluated in recent decades, but also because of the change in the way we think about the environment around us and the frameworks created...
Mountain depopulation is a worldwide phenomenon observed in all continents. It has varied socio-economic reasons; among others, the low profitability of traditional agriculture, the better job possibilities and the higher level of services in urban settlements. However, it is often recognized that depopulation is related to natural factors such as...
Dolines, or closed karst depressions, are the most characteristic feature of karst landscapes. The two main types of doline are those formed by the removal of material by solution and those formed by the geological processes of collapse or suffosion. Solution dolines are most frequently found in carbonate karst in high relief karst massifs. Various...
Floods are one of the most common natural hazards and as such, they are causing a great loss of human life as well as great economic damages. Flood frequency analysis (FFA) is still an active and popular field of research among geographers. In this study we have performed regional flood frequency analysis (RFFA) using the L-moments method and annua...
The number of MSc and BSc geography students has been constantly decreasing in Hungarian universities over the past 8–10 years. This negative trend fits into a general decline in student numbers in Hungary since 2005. Therefore, our aim was to conduct a nationwide survey among Geography MSc and BSc graduates, in order to reveal employment opportuni...
Vikos-Aoos Geopark is part of the European and Global Geopark Networks of UNESCO since 2010 and it is located at the NW part of the Pindus Mountain Range at Epirus Region, northwestern Greece. The Geopark extends in an area of 1.200 km2 from the area of Northern Pindus National Park to the Greek-Albanian borders. The area is characterized by a moun...
This study, which builds on high-precision unspiked Cassignol-Gillot K-Ar age determinations, presents an advanced DEM-based volumetrical analysis to infer long-term magma output rates for the Late Quaternary Ciomadul (Csomád) dacitic lava dome complex (East Carpathians, Romania). The volcanic field of Ciomadul developed on the erosional surface of...
Due to unfavourable natural conditions (poor soils, lack of water, special relief conditions), karst terrains have always been relatively sparsely populated, and they have been seriously affected by recent depopulation processes. However, the creation of national parks on karst terrains and the recent increase of (geo)tourism may influence and even...
Glaciokarst terrains are rich not only in specific landforms, but in subsurface forms as well. Long, complex cave systems are widespread in glaciokarst terrains, and the deepest caves are almost all found in glaciokarsts. On the other hand, as for the volume of cave chambers and passage dimensions, glaciokarst caves are not among the largest ones....
In this chapter, notable glaciokarsts of the world are presented. Geographical location, geologic and tectonic settings, climatic conditions, glaciation phases as well as surface and underground karst landforms are presented about each selected region. Obviously, the areal extent, the degree of exploration and the amount of publicly available infor...
In this chapter the research history of glaciokarsts is described from 1880 in the following topics: morphological descriptions (landforms on glaciokarst terrains, cave explorations on glaciokarsts), hydrologic and speleological analysis of subglacial and periglacial karst aquifers, new methodologies in glaciokarst research (dating methods, formal...
Karst terrains have varied abiotic and biotic values. However, due to their unfavourable conditions for human settling, they are generally relatively sparsely populated areas. Thus, karst terrains merit and are suitable for nature protection. In this paper, (partly) karstic European geoparks are studied. We compiled a dataset based on official info...
Tara National Park (Serbia) founded in 1981 is well known for its biodiversity and karst landforms. However, until now, only little information has been published about the geomorphological characteristics of Tara NP. Thus, in this paper, we demonstrate the high geodiversity of Tara NP and we analyse the geomorphology by using both GIS tools and fi...
Since the foundation of Yellowstone National Park (1872), the national park (NP) concept has been transformed several times. Important elements of the present NP concept are: the protection of "pristine" nature, national identity, tourism, protection of cultural landscapes and historical heritage, recreation, scientific research, education, ecologi...
Formerly, sand dune patterns were investigated mostly by aerial and satellite images, but more recently, geomorphometric analysis based on digital elevation models (DEMs) has become an important approach. In this paper, sand dune patterns of Grand Erg Oriental (Sahara) are studied using the De Ferranti (2014) DEM, which is a blending of SRTM (Shutt...
Karst landscapes are generally rich in spectacular geomorphological and speleological phenomena. On the other hand, karst terrains are less suitable for traditional, agricultural land use. Historically, these settings meant mostly disadvantages, hence karst landscapes remained less densely inhabited and poor regions relatively to their neighboring...
Karst terrains are generally unfavourable for human settlement. However, these natural environments can be relatively well preserved, and given their special geologic and biologic settings, they often became protected areas. In many cases, European karst-lands are poor areas, affected by depopulation in the second half of the 20th century. However,...
Due to the increasing awareness about geoparks, some mayors in the Bükk region initiated the creation of the third geopark of Hungary, hence it is a nice example of bottom-up initiatives. At present, Hungary has two UNESCO Global Geoparks, the Novohrad-Nógrad Geopark, which was the first international geopark, and the Bakony-Balaton Geopark. While...
During the Late Bronze Age, the island of Santorini had a semi-closed caldera harbour inherited from the 22 ka Cape Riva Plinian eruption, and a central island referred to as ‘Pre-Kameni’ after the present-day Kameni Islands. Here, the size and age of the intracaldera island prior to the Late Bronze Age (Minoan) eruption are constrained using a pho...
Hyperspectral satellite data is an efficient tool in vegetationmapping; however, previous studies indicate that classifying heterogeneous forests might be difficult. In this study, we propose a mapping method for a heterogeneous forest using the data of the Earth Observing-1 (EO-1) Hyperion supplemented by field survey. We
introduced a band reducti...
Reconstructing ‘Atlantis’, the Late Bronze Age island of Santorini
The study of human-environment relationships in mountain areas is important for both theoretical and practical reasons, as many mountain areas suffer similar problems, such as depopulation, unemployment and natural hazards. Medium mountains constitute a special case within mountains, because they are more populated but less attractive as tourist de...
Doline morphometry has always been in the focus of karst geomorphological research. Recently, digital terrain model (DTM) based methods became widespread in the study of dolines. Today, LiDAR datasets provide high resolution DTMs, and automated doline recognition algorithms have been developed. In this paper, we test different datasets and a doline...
The transition zone between the subsiding western Pannonian Basin and the uplifting Eastern Alps is a slightly undulating hilly realm, consisting of large plateaus, pediment surfaces and locally steep scarps. These rectilinear slopes are considered as being controlled by structural elements as suggested by the digital elevation model (DEM), althoug...
Human-environment relations have some special characteristics on karst terrains, and karstlands are usually less densely inhabited areas principally due to hydrologic, topographic and pedologic reasons. However, the natural factors of karst terrains and socio-economic development are rarely discussed together, and the relationships are usually expr...
In this article we analyse the human-environment relationships in geographical research from the end of the 19th to the beginning of the 21st century. We highlight paradigms, which affected our way of thinking about man-environment relations. Discussing scientific approaches and paradigms in geography the leading scientists who had influential thou...
The study area is situated between the uplifting Alps and the subsiding Little Hungarian Plain, between 16°–17° E and 47°–47.5° N. The differential vertical motion implies neotectonic activity and some associated geomorphologic features (e.g. wind gaps, small streams in large valleys, etc.) may be observed as a result of drainage reorganization. Af...

Drainage network evolution of the Trascău Mts, including the formation of the famous gorges (e.g. Cheile Turzii) is constrained by the transitional position between the high central Apuseni Mts and the Mureş Valley, further on by the ~N-S oriented geologic settings. The aim of this study is to use digital terrain analysis tools in order to better u...
In this paper we proposed a two step method to classify forest areas on a species/genus level with
hyperspectral satellite images using the data of NASA’s EO-1 Hyperion. Our first step was to reduce the bands of the training samples in a way their spectral angle will be higher – raising the accuracy for the SAM supervised classification method. We...
Relationships between environmental and social factors have long been studied by geographers. Nowadays, GIS-aided statistical analysis provides new tools to explore these relationships. In order to detect the impact of topography on social factors, we selected the country of Montenegro as a case example due to its high topographic variability. We c...
Human-environment relationships have long been in the focus of geographic studies. in this paper, a giS-aided statistical analysis is carried out to explore the intensity of these relation-ships for selected environmental and social factors with special emphasis on karst landscapes. The study area is the Gömör–Torna (Gemer-Turňa) Karst and its broa...

A digitális terepmodellek feltűnnek a különböző földtudományoktól az
agrártudományokon át a mérnöki tervezésig, sőt a játékprogramokig. Lévén, hogy a szerzők között egy geográfus és két geofizikus található, ez a tankönyv elsősorban a földtudományok téma iránt érdeklődő hallgatóinak szól, célként kitűzve eg...
Steep, rectilinear slopes are frequently considered as being controlled by structural elements. A number of studies automatically take the linearity of landforms as prove for structural, most frequently fault control. However, this logical but not unequivocal conclusion needs careful verification, because divers geomorphic process alone can also res...
The timing of Late Pleistocene volcanic activity of the Ciomadul (Csomád) dacitic lava dome complex, site of the youngest eruptions in the Carpathians, has been constrained by morphometric analysis and radiometric chronology. Peléan domes and asymmetric domes/coulées built up the volcano, including the central edifice that hosts the youngest twin c...
Relationships of environmental and human factors have always been in the foreground of geographical thinking. According to geographic determinism theory, which was formulated in the 19th century, the social development of a region is decisively influenced by natural factors. On the contrary, geographic nihilism denies the importance of natural sett...
Transition zones between uplifting and subsiding units are usually

parts of the Eastern-Alps), that are the parts of the Rechnitz Penninic
Window. These metam...
Volcanic evolution of the Ciomadul (Csomád) lava dome complex,
site of the youngest (Late Pleistocene, late Marine Isotope Stage 3)
eruptive activity in the Carpathians, has been studied by advanced
morphometry and radiometric (U/Pb, U/He and 14C) geochronology. The
volcano produced alternating effusive and intermittent explosive
eruptions from ind...
Erosion patterns and rates of 33 stratovolcanoes in the arid to hyperarid Central Andean Volcanic Zone (14°S to 27°S) have been constrained by morphometric modelling. All selected volcanoes belong to the short-lived, symmetrical, circular andesitic stratocone type, with ages spanning 14Ma to recent. Starting from the initial, youthful volcano morph...
Classical single-line elevation profiles often comprise some arbitrariness. Swath profiles can overcome this problem since the elevation values are considered not only along a line but along a swath. In a swath profile, the pixels are classified according to distance and statistical parameters (min, mean, max) of the classes are plotted against dis...
The Trascău Mountains are located in the eastern part of Apuseni Mountains. The 400–1400 m high mountains are lithologically compound and from a morphological viewpoint, Jurassic Limestone terrains are the most characteristic. Three denudation surfaces at different altitudes were described by previous researchers. Deep-walled transversal valleys (g...
BEVEZETÉS Napjainkban az alapkutatásokban sajnálatosan kis szerephez jutnak a természet-és társadalomföldrajz egységét megjelenítő kutatások. A fenti megállapítás alól kivételként említhetők a környezetvédelemhez kapcsolódó vizsgálatok, amelyek az embernek a környezetére gyakorolt – általában negatív – hatásait elemzik. A karsztvidékeket, amelyek k...
The surface of the Gömör–Torna/Gemer–Turňa Karst (GTK) was largely formed by Pannonian or Pliocene pediplanation. Although this surface has been dissected by subsequent tectonic and fluvial processes, the present karst plateaus still preserve large pieces of this once homogeneous surface. GIS-based statistical methods have been used to calculate ex...
In this paper, by the example of Canin Massif, it is demonstrated, how GIS-techniques can be used for the study of high mountain karst terrains. In case of Canin, elevation and slope histograms show characteristic differences in plateau levels and landforming processes between the northern, western and southern sectors of the mountains. Ridge and v...
The cone-building volcanic activity and subsequent erosion of San Francisco Mountain, AZ, USA, were studied by using high-resolution
digital elevation model (DEM) analysis and new 40Ar/39Ar dating. By defining remnants or planèzes of the volcano flanks in DEM-derived images, the original edifice can be reconstructed.
We propose a two-cone model wit...
During the Pleistocene, rivers of the Eastern Alps drained more water into the Pannonian Basin as in recent times. The excess discharge, due to the meltwater of glaciers, transported detrital material from the periglacial areas that built low-relief gravel deposits up in the transitional regions. Today most of these separated gravel plains highly d...
Neogene to Quaternary volcanism of the Central Andes offers a unique opportunity to study long-term erosion of stratovolcanoes. On the basis of SRTM DEM data, we invesigated 35 stratovolcanoes of the 3,800-4,000 m high, arid-hyperarid Altiplano-Puna plateau (from 14oS, 64oW to 27oS, 74oW). The volcanoes have been selected on geomorphological criter...
The Gödöllő Hills, a low-relief terrain within the Central Pannonian Basin in Hungary, is characterised by moderate tectonic deformation rates. Although typical tectonic landforms are not clearly recognisable in the study area, this paper succeeded in discriminating between tectonically controlled landforms and features shaped by fluvial erosion or...
