Water redistribution at the soil surface : ponding and surface runoff in flat areas

In The Netherlands, one of the most important targets for the improvement of surface water quality as aimed for in the European Water Framework Directive, is the reduction of nutrient concentrations (both nitrogen and phosphorus). To identify the most suitable and effective measures for reducing the tranport of nutrients from field to stream, it is important that the processes that control the transport are well identified and quantified. The PhD research presented in this thesis was part of the Alterra project “Relationships between groundwater and surface water
