Evaluation of TOPMODEL for prediction of the runoff of a watershed under different land uses

The applicability of TOPMODEL hydrologic model to predict the runoff hydrographs originated from isolated rainfall events over a small watershed under conservationist management practices was evaluated. Geographical, hydrological and soil data from the watershed were used associated to streamflow hydrographs and rainfall events measured between 2009 and 2012. TOPMODEL mainly underestimated runoff peak flow and runoff amount. However, it was observed that TOPMODEL is promising for the estimation of runoff hydrograph originated from isolated rainfall events at the studied small watershed under conservationist management practices.
