| Research Abstract |
Distributed hydrological models usually have cell-size dependence: model parameters must be readjusted when the digital elevation model (DEM) resolution is changed. In this work, we propose a simple scaling algorithmfor TOPMODEL, a conceptual rainfall-runoff model. Combining it with the routing method, we finally obtain a scale-independent distributed hydrological model.
