Abstract The European Water Framework Directive demands to assess and report the chemical ecological status of water bodies (WB). Linking their drivers pressures deriving suitable mitigation measures require knowledge shape area WB catchments. We derived a network 26 570 catchments in Germany using hydrologically‐defined drainage basins German federal states. established 338 149 basins. This un...

The paper presents the results of stationary, detailed studies on variability mutual share two fluvial loads, i.e., suspended solids and dissolved material during floods caused by rainstorm, continuous rainfalls snowmelt in selected rivers (Silnica, Sufraganiec) draining small catchments central Poland, including characterized a high level urbanization. Irrespective origin flood, load did not e...

Determining the role of different precipitation periods for peak discharge generation is crucial for both projecting future changes in flood probability and for shortand medium-range flood forecasting. In this study, catchmentaveraged daily precipitation time series are analyzed prior to annual peak discharge events (floods) in Switzerland. The high number of floods considered – more than 4000 ...

Peters, E., 2003. Propagation of drought through groundwater systems Illustrated in the Pang (UK) and Upper-Guadiana (ES) catchments. Ph.D. thesis, Wageningen University, The Netherlands. 203 pp. The transformation of droughts as a result of the propagation through groundwater systems is examined by comparing droughts in time series of groundwater recharge, levels and discharge. The groundwater...

We use the Variable Infiltration Capacity (VIC) land surface macroscale hydrology model driven by observed maximum and minimum air temperatures and precipitation to map daily soil moisture values over China for the period 1 January 1971 to 31 July 2005. The model is applied over a grid of 10 458 points with a resolution of 30 km × 30 km. The model is first calibrated using observed hydrographs ...

Spatial and temporal patterns in streamwater acidity are ecologically important, but difficult to measure in parallel. Here we present the spatial distribution of streamwater chemistry relevant to acidity from 60 stream sites distributed throughout a 67 km2 boreal catchment, sampled during a period of winter baseflow (high pH) and during a spring flood episode (low pH). Sites were grouped based...

[1] This paper assesses the extent to which a topographically defined description of the spatial arrangement of catchment wetness can be used to represent landscape hydrological connectivity in temperate river catchments. A physically based distributed hydrological model is used to characterize the space-time patterns of surface overland flow connection to the drainage network. These characteri...

In flow forecasting, additionally to the need of long time series of historic discharges for model setup and calibration, hydrological models also need real-time discharge data for the updating of the initial conditions at the time of the forecasts. The need of data challenges operational flow forecasting at ungauged or poorly gauged sites. This study evaluates the performance of different choi...

Soil erosion is one of the most critical environmental hazards of recent times. A large area suffers from soil erosion, which in turn, reduces productivity. Methods such as the Universal Soil Loss Equation or Revised Universal Soil Loss Equation are widely used for the estimation of soil erosion from catchment areas. The paper deals with the estimation of soil erosion using Universal Soil Loss ...
