The paper presents a conceptual model of the route of macroplastic debris (>5 mm) through a fluvial system, which can support future works on the overlooked processes of macroplastic storage and remobilization in rivers. We divided the macroplastic route into (1) input, (2) transport, (3) storage, (4) remobilization and (5) output phases. Phase 1 i...
Plastic waste poses numerous risks to mountain river ecosystems because of their high biodiversity and distinct physical characteristics. Here, we provide a baseline assessment for the future evaluation of such risks in the Carpathian Mountains, one of the most biodiverse mountain ranges in Eastern-Central Europe. We used high-resolution databases...
Information on the transport and deposition of riverine macroplastic is crucial for selecting proper locations for river cleaning actions and for trapping infrastructure installation. Obtaining such information for mountain rivers is of particular importance because their specific characteristics make them particularly prone to illegal dumping, pla...
Mountain rivers are typically seen as relatively pristine ecosystems, supporting numerous goods (e.g., water resources) for human populations living not only in the mountain regions but also downstream from them. However recent evidence suggests that mountain river valleys in populated areas can be substantially polluted by macroplastic (plastic it...

The water depth and flow velocity of a river may be temporarily disturbed by the water level fluctuations connected with the operation of artificial dam reservoirs located downstream (so-called backwater fluctuations (BF)). In this research, we use the two-dimensional hydrodynamic model iRIC MFlow_02 to quantify the effects of BF on the lowermost s...
Macroplastic storage in mountain rivers remains unexplored and it is unknown how river morphology and different surface types of river areas modulate this process. Therefore, we sampled macroplastic debris stored on the surface of emergent river areas with different vegetation cover and on wood jams in a channelized, single-thread reach and an unma...
Amounts of macroplastic debris stored on different elements of mountain rivers are unknown, but such data are crucial to plan future mitigation activities in these fragile ecosystems. We determined the amounts of macroplastic stored on different surface types (geomorphic units and wood jams) in two reaches of the Dunajec River in the Polish Carpath...
Mitigation of adverse effects of channel incision and the loss of alluvial bed substrate on the ecosystems of mountain watercourses downstream from check dams requires effective sediment entrapment in the incised channels. We examined changes in the ecosystem of mountainous Krzczonówka Stream, Polish Carpathians, resulting from lowering of a high c...
The construction of a high check dam on mountain Krzczonówka Stream, Polish Carpathians, in the mid-20th century caused numerous detrimental changes to the downstream reach. In 2014 the check dam was lowered to make the structure passable for river biota. Before that, several block ramps were constructed in the deeply incised downstream reach to fa...
Processes of macroplastic (plastic particles > 5 mm) storage and remobilization in rivers have been overlooked so far, but are of crucial importance for the estimation of plastic accumulation and transport and associated risks. We present a conceptual model that defines phases of the macroplastic route through a fluvial system and systematizes thei...
Relatively short time that passed since the onset of river restoration activities worldwide and a scarcity of monitored restoration projects cause that scientific evidence of changes in restored rivers is still meagre, particularly with respect to innovative restoration techniques and long-term effects of restoration activities. Restoration project...
2D numerical modelling indicated that backwater fluctuations of the Czorsztyn Reservoir increase floodwater depth (up to 255%) and decrease flow velocity (up to 72%) and bed shear stress (up to 80%) in the backwater zone of the mountainous Dunajec River. They also trigger further morphological changes, which additionally modify the initial river hy...
Upstream from a dam reservoir, river hydrodynamics may be directly changed by temporary inundation driven by the reservoir. This triggers morphological river changes which may additionally modify the initial hydrodynamics, even at the time when backwater inundation does not occur (indirect effects of backwater). We verified these hypotheses, applyi...
Woreczki foliowe przyczepione do drzew i plastikowe butelki unoszące się na wodzie stały się w ostatnich latach częścią krajobrazu rzecznego. Masowa produkcja plastiku i związana z nią dostawa plastikowych odpadów do środowiska rozpoczęła się w latach 60. ubiegłego stulecia. Od tamtego czasu obecność cząstek plastiku stwierdzono w wodach morskich i...

Dam reservoir construction is one of the most important factors shaping river-valley morphology in the Anthropocene. While a large number (>58,000) of these constructions are in operation all over the world, we remain quite ignorant of what happens upstream of them (in so called backwater zone), especially for the case of gravel-bed rivers. Existin...
In the last decade the increasing availability of low-cost, consumer-grade drones (UAV) and structure from motion (SfM) photogrammetry revolutionized the way of topographic data collection in geomorphology and other sciences. The SfM photogrametry allows for easy and low time-consuming production of centimetre-scale digital elevation models (DEMs)...
A model is presented which provides a guidance for further biogeomorphological research on rivers affected by temporary inundation of their channel and floodplain caused by so called backwater fluctuations (BF) upstream from a dam reservoir (within so called backwater fluctuations (BF) zone). Backwater influences on rivers were divided into: (i) fi...
Only in the years 2007–2016 about 8000 large dams were constructed all over the world, adding to >50,000 previously built dams. These structures disturb abiotic and biotic components of rivers, but to date the knowledge of their impacts has been mainly derived from observations of downstream river reaches. Upstream from dams, however, backwater flu...
In the twentieth century the heavily channelized Raba River incised deeply in its mountain course. Abandonment of channelization structures in a 2.3-km-long reach within a forested corridor was followed by considerable channel widening during floods of 30- and 35-year recurrence interval, re-establishment of a multi-thread channel pattern and islan...
The proposed model indicates that backwater-induced changes in flow and sediment dynamics create conditions changing biogeomorphological functioning of a gravel-bed river.
Tylko w latach 2007-2016 powstało na świecie około 8000 nowych, dużych zbiorników zaporowych a ich łączna liczba wynosi obecnie około 58000. Budowle te oddziaływują na abiotyczne i biotyczne elementy systemu fluwialnego, jednak do tej pory wiedza na temat ich wpływu na koryta rzek była uzyskiwana głównie na podstawie obserwacji odcinków rzek poniże...

It is widely known that dams disturb abiotic and biotic components of the fluvial systems, but to date the knowledge of their impacts has been mainly derived from observations of downstream river reaches. In contrast, little is known on the biogeomorphological ad...
Investigations of islands in an undisturbed reach of the Czarny Dunajec River in the Polish Carpathians indicated that islands are very dynamic landforms and greatly contribute to the overall plant diversity of the river corridor [1]. This was the basis of the hypothesis that re-establishment of islands may be an important factor in the restoration...
Zbiorniki zaporowe zaburzają przepływ wody i rumowiska w korycie i na równi zalewowej rzeki, prowadząc do zmian sedymentologicznych i hydromorfologicznych. Dotychczas nie analizowano przebiegu zmian roślinności nadrzecznej w cofkach zbiorników zaporowych zlokalizowanych na rzekach żwirodennych. We wcześniejszych pracach zauważano jednak, że roślinn...
Na świecie funkcjonuje obecnie ponad 58 tys. dużych zbiorników zaporowych, z czego aż 8 tys. powstało w ostatniej dekadzie. Budowle te zaburzają przepływ wody i rumowiska w korytach rzecznych. Uznaje się, że zbiorniki zaporowe są jednym z głównych czynników kształtujących zmiany rzeźby dolin rzecznych w Antropocenie. Jednak na uwagę zwraca fakt, że...
More than 50,000 large dams (with the height above 15 m) operate all over the world and, thus, they significantly disturb water and sediment transport in river systems. These disturbances are recognized as one of the most important factors shaping river morphology in the Anthropocene. Downstream effects of dams have been well documented in numerous...
Because of long-lasting sediment starvation, channel reaches downstream of dams are typically deeply incised and thus the sediment flushed out from the demolished or lowered dams may not be trapped in these reaches but transported far downstream. To enable entrapment of sediment in such a deeply incised channel, artificial boulder ramps were constr...
Little is known on the planform evolution of gravel-bed rivers in base-level raised backwater zones upstream from dam reservoirs. The general model of river channel response to base-level rise predicts a decrease in river sinuosity. However, the observations of channel adjustments in the reservoir backwater document a narrower and more sinuous chan...

Studies of gravel-bed rivers have shown that in-channel sedimentation may cause flow divergence around deposited bars, that leads to localized bank erosion and additional bar growth (bar-bank interactions). These processes may be of high importance for the river management in the backwater zones upstream of dam reservoirs on gravel-bed rivers. Bar-...
River reaches upstream from dam reservoirs, where water level fluctuations occur due to backwater effects, may be utilized as a field laboratory of base-level rise effects on river morphology. Here I present the results of the aerial photo-based (1963-2012) reconstruction of the long-term morphological adjustments of the small, gravel-bed Smolnik R...
The effects of base-level rising upstream of dam reservoirs on in-channel sedimentation and interaction of the stored sediments with the gravel-bed channel morphology have received little attention so far. Previous studies, however, suggested that the feedback mechanism between in-channel sedimentation and bank erosion may affect channel morphology...

In the northern slope of the Carpathian Mountains and in their foreland, river and stream channels have been significantly transformed by human impact. These transformations result from changing land use in river basins and direct interference with river channels (alluvia extraction, engineering infrastructure, channel straightening). Anthropogenic...
The paper attempts to evaluate the usefulness of historical Austrian maps from the period 1763 – 1787, 1806 – 1889, and 1869 – 1887 in the reconstruction of the cultural landscape of southeastern Poland, occupied by the Austrian Empire throughout the 19 th century. Three towns were analyzed using historical Austrian maps – Kalwaria Zebrzydowska, Od...
In this study the changes of the gravel bar area and the channel width were analysed in the base-level raised section of the gravel-bed Dunajec River upstream from the Czorsztyn Reservoir (CR) (Polish Carpathians). The construction of the CR and the large flood which occurred in 1997, as well as the existence of aerial imagery taken before (1982, 1...
In order to compare the results of the reconstructions of depositional environment of sediments performed using the C/M diagram (Passega, Byramjee 1969) and the cumulative curve analysis (Visher 1969), 49 samples of overbank sediment were collected in the valley of the Dunajec River. The samples were collected from the fill of an abandoned channel...
Information on the magnitude of the measurement error is necessary to assess the magnitude of changes that may be identified during an analysis. In this paper, the impact of the aerial photo scale and the measurement scale in the GIS software on the magnitude of the digitization (identification) error of a river channel bank was analysed. Repeat di...
The geomorphological literature lacks theoretical works necessary to build hypotheses and predict changes in alluvial river channels above dam reservoirs in the area of the so-called backwaters. The paper presents concepts of a model based on Lane's principle of equilibrium. Lane's principle of equilibrium shows changes in the components of an allu...
The experimental use of a statistical algorithm and GIS for detecting the spatial reach of the impact of a dam reservoir on the development of a river channel. The case of the Dunajec and the Białka rivers, the Polish Carpathians Maciej Liro Poland (maciej.liro@uj.edu.pl) The determination of the spatial reach of the impact of dam reservoirs on the...
Most of geomorphological studies related to the impact of dam reservoirs are focused on its effect on the river channels downstream of dams. However, little is known about the evolution of river channels upstream of dams (in backwater areas). In this paper I propose a conceptual model of alluvial channel changes in the backwater. It assumes that th...
In the last century the Dunajec channel in its lower river course was considerably transformed due to channelization works. The former multi-thread river channel was replaced by a single one, resulting in abandonment of side channels. Groynes were constructed on both main and side channel. Quick filling up of the inter-groyne basins reduced channel...
The intensity of tourist traffic in Pieniny National Park – PNP shows a significant spatial diversity. Its highest rates occur on trails in the eastern part, where major attractions of the PNP are located. The lowest intensity of tourist traffic is noted in the western part. On the most popular trails intensity exceeds the value of tourism carrying...

This scientific project follows two river restoration projects realized in the first half of the 2010s in three Polish Carpathian rivers with cost-effective
methods of (i) establishing an erodible river corridor and (ii) constructing block ramps in an incised channel totrap bed material and aggrade the channel bed. Using environmental data collected at the beginning and end of these projects and data collected within the proposed research project five years after the end of the restoration projects, we will assess the immediate (during the restoration project) and longer-term efficiency of the restoration measures in improving
the ecological state of the rivers and reducing flood hazard.
Riparian (streamside) zones are dynamic ecosystems that form at the interface of aquatic and terrestrial components of the landscape. They are shaped by underlying physical processes associated with river flow, including the erosion and deposition of sediment, periodic inundation, and groundwater–surface water exchanges. In their natural state, riparian ecosystems are characterized by high spatial and temporal heterogeneity, which supports a diversity of species, habitats, and ecological processes. Today, across much of the world, rivers and their riparian zones have been profoundly modified by human activities associated with river management (e.g., dams and flow regulation) and land use pressures (e.g., agricultural conversion and irrigation withdrawals), altering the patterns and processes that sustain riparian functions and biodiversity. Monitoring and the assessment of riparian ecosystems is challenging. Recent advances in remote sensing methods enable effective mapping, monitoring, and improved understanding of riparian systems and management outcomes. High-resolution imagery (satellite, aerial, and UAV) and digital elevation models (DEMs) constructed from LiDAR and UAVs are powerful tools for assessing the biophysical dynamics of riparian zones (e.g., hydrology, geomorphology, and vegetation) over time and three-dimensional space. Machine learning techniques can provide important insights about the long-term spatiotemporal dynamics of riparian systems (e.g., vegetation succession, habitat conditions, the extent and turnover of geomorphic surfaces) and their associated ecological functions.

This project aims to explore the processes of and controls on macroplastic (plastic particles > 5-25 mm) storage in mountain and foothill river environments – the phenomenon which has not been explored so far but is of crucial importance for estimation of how much and where plastic is stored in riverine ecosystem and related risks.
We plan to use four streams in the Polish Carpathians with different levels of human pressures in their catchments and channels to determine relations between macroplastic abundance in river and: (a) physiographic and antropogenic characteristics of river catchments, (b) river morphology, and (c) riparian vegetation cover.
First step of the project is to built a conceptual framework with terminological and theroetical background for future studies on this unexplored topic.
Next we plan to quantify the importance of the natural and anthropogenic characteristics of fluvial systems on macroplastic storage and remobilization in different type rivers and streams in southern Poland.
Ultimately, we aim to estimate how much plastic has accumulated in rivers and will be present in future riverscapes and how this processes will interact with human.
We plan to use full geographical perspectives that would include among functional components humans, who not only dispose plastic, but are also afected by it both physically and aesthetically,
and who may remove it from rivers.
