Chapter
In the mountains of the Balkan Peninsula, a variety of landforms have been documented since the late nineteenth century that are predominantly, or at least to some extent, a result of periglacial processes. To date, some comprehensive periglacial studies have been carried out in the Rila-Rhodope Massif, while the other mountains of the Balkan Penin...
Article
Snezhnika and Banski Suhodol glacierets in the Pirin Mountains are the southernmost surface ice accumulations in Europe. Apart from direct snowfall, substantial inputs from avalanching feed both glacierets. Both glacierets appear to be more stable than any other small glacier in the Mediterranean region. Although accurate knowledge of ice thickness...

Very small glaciers (glacierets) react strongly to climatic variations. This is well expressed in their interannual size changes, which are most evident in autumn, at the end of the glacial mass balance year. This study presents results from the detailed research of two very small glaciers in the highest northern part of the Pirin Mountains of Bulg...
Article
Full-text available
Periglacial landforms are typical features of the high mountain environment on the Balkan Peninsula. Their formation and diversity is determined by climatic, topographic and geological factors. Presently active periglacial processes occur above 1700-2000 m a. s. l., while relict features are observed down to 1100-1400 m a. s. l. Among the most prom...

This study presents results from regular observation of permanent and summer-persisting firn-ice bodies in the highest parts of the Dinaric Alps. The sizes of six small glaciers and two snow patches on the Prokletije Massif (in Albania) and the Durmitor Massif (in Montenegro) were measured from 2011 to 2018. In recent years, specific cycles of inte...
Article
Full-text available
Rock glaciers are lobate or tongue-shaped assemblages of poorly sorted, angular-rock debris and ice, commonly found in high mountain environments, which move as a consequence of the deformation of internal ice (Giardino and Vitek, 1988; Barsch, 1996). However, in most research works, when discussing the formation of these features, the focus has be...
Article
Full-text available
This study presents a review on Holocene glacial traces in Bulgaria. Pleistocene glaciation in this territory was spread over a number of mountains above 2000 m a. s. l., while in the later time, it was restricted only to the highest areas of the two highest mountains, Pirin and Rila. Two major phases can be distinguished on the basis of field evid...
Article
The proposed research addresses the problem of permafrost occurrence for the first time in the highest mountains of the Balkan Peninsula. The likely/unlikely presence of ice-rich permafrost in 13 rock glaciers in the Rila and Pirin Mountains was investigated using thermal measurements (e.g., ground surface temperature monitoring, measurements of th...

Full-text available
The article presents the latest views about the origin of Hridsko lake in the mountain range Bogicevica, an eastern part of Prokletije massif (Dinaric range). Previous studies define the lake, which is situated at 1980 m a. s. l., and occupies an area about 3,5 ha, as a cirque lake, formed after the retreat of wuerm-ian glaciers following the class...
Article
Full-text available
Small glaciers on the Balkan Peninsula are tiny masses of firn and ice (areas from 0.5 to 5 ha) which have been proved permanent at least since the coldest phases of the Little Ice Age, and are slowly moving under their own gravity. These are considered glacial, but also karstic features at the same time, because the topography that provides for th...
Article
This research reveals relationships between climate variables and inter-annual dynamics in the area of the glacieret located in the cirque Golemiya Kazan in the Pirin Mountains. The study period is 1993–2017. The correlations are identified using statistical methods. Also, a statistical model is constructed, including some climate variables as pred...
Article
The present article is focused on high mountain relief in marble, which combines glacial, periglacial and karstic morphology. High mountain karst is found in Northern Pirin (Vihren and Sinanitsa area) and central Pirin (Orelek area), the latter lacking traces of glaciation due to its low altitude. In the most representative area, Vihren part, sever...

The present study makes a comparison of the development of karstic processes and their landform expression in two representative high mountain areas on the Balkan Peninsula: Durmitor (Dinaric chain, Montenegro) and Pirin (Rhodope massif, Bulgaria). Main accent is put on epikarst and its features. On the background of many similarities: strong glaci...
Article
Mountain glaciers are among the best environmental indicators of short-term climatic variations. Although presently there are no classical glaciers on the Balkan Peninsula, mountains in this part of Europe comprise a number of small but permanent firn–ice patches, which can be determined as small glaciers. Most of them can be categorized as glacier...
Article
Full-text available
Contemporary traces of Würm glaciation in Northeastern Pirin and Northeastern and Central Rila proved to be an important benchmark for intensity and character on orogenesis in eastern part on the Balkan Peninsula. The young age of relict glacial forms in our highest mountains /not older than LGM age, 24-18 ka BP/, and the almost complete absence of...

Physiographic conditions for occurrence of river floods and inundation in small watersheds of southwestern Bulgaria on the example of Aidarovska River, a left affluent of Struma River, are considered. The morphometric parameters of the drainage basin are calculated based on GIS. The presented own data show that this type of processes are widely spr...
Chapter
The highest Bulgarian mountains, Rila (2925 m a.s.l.) and Pirin (2914 m a.s.l.), provide groups of relatively well preserved glacial landforms from late Pleistocene and Holocene cold phases, several small recent perennial ice features, and still well preserved forest ecosystems at the tree limit that can serve as a source for valuable environmental...

Mountain glaciers are among the best natural indicators of short-term climatic variations. Although presently there are no classical glaciers on the Balkan peninsula, mountains in this part of Europe comprise a number of small but permanent firn-ice patches, which can be categorized as embryonic glaciers. They are subdivided into: typical glacieret...

Glacial moraines in the central South Carpathian Range (Fǎgǎraç Mountains, Romania) have been mapped in order to reconstruct the elevation of the climatic snowline (ELA) during the Last Glacial Maximum (LGM). In a representative north-south cross-section, depositional ages of moraine complexes have been determined by 10Be exposure dating. In the st...
Chapter
Morphostructures exert a strong control on the landforms of Bulgaria as in the mountain landscapes planation surfaces prevail. In mountains valley incision is considerable, deep and narrow gorges and cross-section asymmetry of valleys is common. In major valleys two flood and seven upper river terraces have been identified. Regionally, active karst...
Article
Relict glacial landform complexes have been studied in the mountains of the central Balkan Peninsula since the end of the 19th century. Since their existence was proved for the first time by Cvijic, various authors have debated the number of glacial phases, as well as their age. At present, the problem of age determination is being solved by the ap...
