Conceptual rainfall-runoff model with limited and low quality data in the Pirai River basin, Bolivia

In zones where limited data to apply a distributed hydrological model is available, a combination of lumped conceptual models with channel routing may be a useful tool in the support system for catchment planning. In this approach the whole basin is divided into sub basins, and for each sub basin a lumped conceptual model is built-up. In the present case study the lumped model is NAM and the GIS environment is performed by MIKE BASIN which introduces the hydrological modeling tools into ArcGIS 9.2.
