| In the recent years development of global coverage satellite-based data makes them suitable to use for prediction in ungauged or poor data basins. Moreover, a proxy catchment also can closely resemble the hydrological behavior of target basin. This study has presented modeling runoff generation for prediction hydrological responses in large basins with lack of access to observed data. A parsimonious distributed hydrological model (BTOPMC) is used. It is shown that how the proxy catchment can be applied for parameter estimation of an ungauged-large basin. Despite of the underestimation of flow volume by satellite-based precipitation, the overall performance of application is encouraging for long term modeling in large basin. The result gives motivation for application of method in ungauged or poor data basins using proper proxy catchment. |
