Ecological processes in floodplains may function differently across climate regions. We compared the river discharge, water chemistry, and nutrient budget and balance of floodplain vegetation in a temperate climate (River Narew, Poland) with those in a tropical climate (River Songkhram, Thailand). Both rivers show a discharge regime with a flood pu...

Long-term simulated water balance and streamflow data for the territory of Poland with high spatio-temporal resolution were reconstructed for the period 1951–2020 with a daily time step, using the Soil and Water Assessment Tool (SWAT) hydrological model. The spatial structure includes 4,381 sub-basins and 47,725 hydrological response units. The SWA...

Soil is a major natural resource fundamental for food production, and a habitat for living organisms. It is therefore extremely important to prevent its erosion. It is assumed that 50% of erosion at the global scale is caused by water. A relatively low number of studies model soil loss in Northern and Eastern Europe. Although that region currently...
Article
Channel morphodynamics, governed by erosion and deposition processes, constitute a relevant aspect of integrated water management planning, and development of sustainable fluvial projects. According to the Water Framework Directive, there is a need for hydromorphological recognition and channel geomorphic adjustment at the national level. Such a la...

Floods are naturally occurring extreme hydrological events that affect stream habitats and biota at multiple extents. Benthic macroinvertebrates (BM) are widely used to assess ecological status in rivers, but their resistance and resilience to floods in medium-sized, temperate, lowland rivers in Europe have not been sufficiently studied. In this st...

Projected changes of temperature and precipitation in Poland were assessed based on downscaled values of CMIP5 climate model projections following two strategies: empirical statistical downscaling (ESD) and dynamical downscaling followed by a bias-adjustment (DD). The ESD method was applied to a large ensemble of climate models, while the more comp...

The main environmental stressor of the Baltic Sea is elevated riverine nutrient loads, mainly originating from diffuse agricultural sources. Agricultural practices, intensities, and nutrient losses vary across the Baltic Sea drainage basin (1.75 × 10⁶ km², 14 countries and 85 million inhabitants). Six “Soil and Water Assessment Tool” (SWAT) models...

Currently, there is a major concern about the future of nutrient loads discharged into the Baltic Sea from Polish rivers because they are main contributors to its eutrophication. To date, no watershed-scale studies have properly addressed this issue. This paper fills this gap by using a scenario-modeling framework applied in the Reda watershed, a s...

The Biebrza wetlands are located in an ice-marginal valley in northeastern Poland and cover some 195 000 hectares. The Biebrza river is not regulated, the valley is not reclaimed and still has marsh, fen and grassland vegetation whereas large scale human interventions in hydrology are absent. The most characteristic feature of the Biebrza river is...

There is a growing pressure on use of the water resources but at the same time, there are growing concerns on the ecological status of surface or ground water dependent ecosystems. Riparian wetlands belong to this group. The ecological characteristics, which describe the status of riparian wetlands, are mostly connected to the phenomena of flooding...

Human activities have led to the loss of a large proportion of biodiversity in riverine wetlands in western Europe (Van Urk 1984; Cirujano et al. 1996). In the second half of the twentieth century, many floodplains, fens, and riparian woodlands were cultivated for agricultural purposes. In addition, the remaining riverine wetlands lost species due...
