| Zusammenfassung |
| In the project RIVERTWIN climate, hydrologic, groundwater and water quality
models are integrated in order to evaluate river basin management plans
established for the implementation of the EU Water Framework Directive. In
such integrated models, which try to simulate all relevant processes in a
river basin realistically, modelling of the water balance plays a key role.
Therefore the integration of hydrological and groundwater models requires
special attention. In this case study, the hydrological model simulates
discharge and daily groundwater recharge in a high spatial resolution. Using
the latter as input, the groundwater model calculates groundwater levels and
groundwater runoff, which is then returned to the hydrological model. Such
integration on the meso-scale brings up new problems such as
commensurability, verification and compatibility of internal state variables
and fluxes, but also provides the possibility to analyse the underlying
assumptions and simplifications. As an example of this modelling approach
the simulation of groundwater recharge, groundwater levels and groundwater
runoff in the Neckar catchment are discussed and the problems of the current
integration concept are described. |
