Using multi-model averaging to improve the reliability of catchment scale nitrogen predictions
multi-model averaging catchment scale nitrogen predictions
2014/12/17
Hydro-biogeochemical models are used to foresee the impact of mitigation measures on water quality. Usually, scenario-based studies rely on single model applications. This is done in spite of the wide...
Modelling the Caspian Sea and its catchment area using a coupled regional atmosphere-ocean model (RegCM4-ROMS): model design and preliminary results
Modelling the Caspian Sea catchment area coupled regional atmosphere-ocean model model design preliminary results
2014/12/16
We describe the development of a coupled regional atmosphere-ocean model (RegCM4-ROMS) and its implementation over the Caspian Sea basin. The coupled model is run for the period 1999–2008 (after a spi...
Evaluation of three different regional climate change scenarios for the application of a water balance model in a mesoscale catchment in Northeast Germany
Evaluation three different regional climate change scenarios application water balance model mesoscale catchment
2010/9/10
Future climate changes might have some impacts on catchment hydrology. An assessment of such impacts on e.g. ground water recharge is required to derive adaptation strategies for future water resource...

Interdisciplinary sharing of knowledge is a key for understanding matter fluxes in landscapes. However, models of transport and reactive fluxes from different disciplines need to work seamlessly toge...
Application of WaSiM-ETH model to Northern German lowland catchments: model performance in relation to catchment characteristics and sensitivity to land use change
WaSiM-ETH model Northern German lowland catchments model performance in relation to catchment characteristics sensitivity land use change
2010/9/10
The hydrological catchment model WaSiM-ETH (Water Balance Simulation Model) is a spatially distributed, process- and grid-based hydrological catchment model which was primarily developed to simulate t...
Impacts of spatial data resolution on simulated discharge, a case study of Xitiaoxi catchment in South China
simulated discharge Xitiaoxi catchment South China
2010/2/3
In this paper we analyse the effects of different spatial input data resolution on water balance simulation using a simple distributed hydrological model: PCR-XAJ model. A data set consisting of land ...
Hydrologic comparison between a lowland catchment (Kielstau, Germany) and a mountainous catchment (XitaoXi, China) using KIDS model in PCRaster
Hydrologic comparison Kielstau Germany
2010/2/3
The KIDS model (Kielstau Discharge Simulation model) is a simple rainfall-runoff model developed originally for the Kielstau catchment. To extend its range of application we applied it to a completely...
Ecohydrological modelling of water discharge and nitrate loads in a mesoscale lowland catchment, Germany
Ecohydrological water discharge
2010/2/3
The aims of this study are to identify the capacities of applying an ecohydrological model for simulating flow and to assess the impact of point and non-point source pollution on nitrate loads in a co...
A meteo-hydrological forecasting chain: performance of the downscaling and rainfall-runoff steps in a small catchment
forecasting performance
2010/1/27
Forecasting ground effects of severe meteorological events with an adequate lead time is fundamental for civil protection scopes and is therefore an important challenge for the scientific community. T...
