Perbandingan Estimasi Curah Hujan Mrr Dan Trmm B342 Sebagai Input Model Hidrologi Hbv Studi Kasus Das Bedadung

Abstract

The limitations of spatial and temporal distribution of rain gauge networks causes inaccuracies in prediction of hydrological modeling. The availability of satellite rain data products is a potential to overcome this limitation. This studies objective is to compare the quality of rain data from the recording of the Manual Rainfall Recorder (MRR) with satellite data TRMM B342 which is entered in the HBV hydrological modeling. Calibration results shows that HBV modeling performance with MRR rain data input is better than TRMM. R2 and NSE values from MRR rain data input were 0.7153 and 0.7133 respectively with a mean error of 89 (mm / year). While the R2 and NSE values of the TRMM B342 satellite rain data input were 0.57 and 0.55 with a mean error of 305 (mm / year), respectively
