Riparian zones can provide a protective buffer between streams and adjacent land-based activities by removing nitrate from shallow groundwater flowing through them. Catchment-scale waterquality models are useful tools for predicting catchment behaviour under various climatic conditions and land-use scenarios. In this paper, we use the Riparian Nitrate Model (RNM) to investigate the potential ro...

[ I ] This study uses time series analysis to examine long-term stream water nitrate concentration records from a pair of forested catchments at the Coweeta Hydrologic Laboratory, North Carolina, USA. Monthly average concentrations were available from 1970 through 1997 for two forested catchments, one of which was clear-felled in 1977 and the other maintained as a control. The time series were ...

Catchment management requires modelling for compliance, investigation, understanding, knowledge capture, and informing decisions. The nature of the problems is variable, ranging across scales both temporally and spatially, including discrete events, long term averages, daily and seasonal dynamics, point and spatial estimates and total catchment outputs. These requirements have spawned a variety...

Hydrological, hydrodynamic and water quality models are often used to simulate surface water in a correct way to be a good basis for decisions regarding the development and management of water resources. Molenbeek is one of the main tributaries of the River Dender basin (Belgium). The hydraulic model is implemented by using the MIKE 11 software of the Danish Hydraulic Institute (DHI). It is a v...

We offer a model for integrated water quality management. The proposed model integrates water protection, land and water use, preservation of ecosystem sustainability, preservation of functional unity of catchment and river flow and socio-economic activity in the catchment. The model has been developed on the basis of combining existing models, including balancing, deterministic (2D) and statis...

Parameterization of physically based and distributed hydrological models for mesoscale catchments remains challenging because the commonly available data base is insufficient for calibration. In this paper, we parameterize a mesoscale catchment for the distributed model HydroGeoSphere by transferring evapotranspiration parameters calibrated at a highly-equipped headwater catchment in addition t...

Catchment urbanisation leads to increased hydraulic and pollutant loadings into receiving waterbodies. Issues concerning pollution that endangers the sustainable utilisation of water resources have focused government authorities towards integrated catchment management, where both causes and effects of pollution are addressed. Recent research has provided a platform for improving urban stormwate...
