Regional analysis and modelling of groundwater runoff components from small catchments in solid rock areas

The description of the basin related water dynamics requires regional information about the source areas of water. In particular the assessment of the land use or climatic change affecting the natural water resources requires reliable and physically-based hydrological information about runoff components, transit times and source areas. To contribute to a feasible solution of the still unresolved task, this theme presents a new approach for the analysis and modelling of subsurface runoff components from small catchments in solid rock areas. The hard rock areas contribute up to 70% of the total runoff. This approach can be characterized as a method for the regionalization of conceptual, physically-based parameters. The aim of the investigations is to design a parameter model as a basis for modelling groundwater runoff components in hydrologically ungauged catchments. This project was part of the special project program (SPP) 'regionalisation in hydrology'.
