Long-term improvement in surface water quality after land consolidation in a drinking water reservoir catchment
land use protection zone soil and water conservation water pollution
2015/3/13
The aim was to explore how soil and water conservation measures, applied in the process of land consolidation, affected nutrient concentrations in surface waters of the Hubenov drinking water reservoi...
Relating extent of colluvial soils to topographic derivatives and soil variables in a Luvisol sub-catchment, Central Bohemia, Czech Republic
digital elevation model digital soil mapping loess soil erosion soil organic carbon
2015/3/10
Colluvial soils, resulting from accelerated soil erosion, represent a significant part of the soil cover pattern in agricultural landscapes. Their specific terrain position makes it possible to map th...
Influence of drainage system maintenance on storm runoff from a reforested, waterlogged mountain catchment
drainage treatment forest soil mountain catchment storm flow runoff waterlogging water retention
2015/3/10
The maintenance of a drainage system in a waterlogged mountain catchment impacted by earlier harvesting operations was assessed on the basis of a hydrological analysis (hydrological balance, three lin...
Assessing sediment enrichment ratio in Mai-Negus catchment, northern Ethiopia
degradation erosion-status sites landform
2015/3/10
Soil degradation is a threat to sustainable development in Ethiopia. However, degradation indicators, such as sediment enrichment ratio (SER), are not adequately documented in literature. This study a...
Selection of catchment descriptors for the physical similarity approach. Part II: Application
a priori SAC-SMA model parameters catchment characteristic MOPEX catchments regionalisation
2015/3/9
This paper demonstrates an application of the previously published method for selection of optimal catchment descriptors, according to which similar catchments can be identified for the purpose of est...
Comparison of rainfall-runoff models for design discharge assessment in a small ungauged catchment
Curve Number design rainfall peak discharge
2015/3/9
Design discharges in a small experimental catchment in Žarošice (Czech Republic) were evaluated using various methods for peak discharge assessment applying 24-h storm rainfalls reduced to s...
Effects of soil depth spatial variation on runoff simulation, using the Limburg Soil Erosion Model (LISEM), a case study in Faucon catchment, France
conditional simulation Faucon hydrograph kriging LISEM soil depth
2015/3/5
Soil depth is an important parameter for models of surface runoff. Commonly used models require not only accurate estimates of the parameter but also its realistic spatial distribution. The objective ...
Long-term changes in runoff from a small agricultural catchment
climate change Poland runoff variability small watershed trend analysis
2015/3/5
River runoff is an important indicator of environmental changes, which usually include climate and/or land use changes, and is also the basis of catchment water management. This study presents results...
Mitigation of surface runoff and erosion impacts on catchment by stone hedgerows
