| Zusammenfassung |
| Sustainable water management requires the quantification of the spatial and
temporal changes of water balance variables. Fully distributed hydrological
simulations of these variables are especially in regions with weak
infrastructure challenging, because the required meteorological input data
are often not available in a sufficient spatial and temporal resolution. One
possibility to deal with this limitation is to provide the required input
data with a meteorological model. This combination results in a one way
meteorological-hydrological coupling system. Within the framework of the
GLOWA-Volta project it is investigated to what extent meteorological models
are able to provide the required meteorological fields with sufficient
accuracy for the hydrological modeling. For this study the mesoscale
meteorological model MM5 and the fully distributed water balance simulation
model WaSiM-ETH were first adapted and validated separately. The research
area is the White Volta catchment in the semi-arid to sub-humid climate zone
in West Africa. The meteorological simulations tend toward overestimating
measured precipitation sums. The coupled meteorological-hydrological runoff
simulations show similar model performances as the simulations driven by
observations indicating the potential of this system for a contemporary
estimation of the terrestrial water balance. |
