Analisis Kejadian Banjir Das Batang Lubuk (Awlr Pasirpengarayan) Menggunakan Datahujan Satelit Trmm Terkoreksi

Satellite-based rainfall data GSMap_NRT is expected to predict and forecast flooding in the area of sub watershed Pasir Pengarayan. Advances in remote sensing technology make it possible to overcome the problem of available data limitations by utilizing data sourced from satellite. The availability of many remote sensing programs connected directly to satellites speeds up the process of collecting data. One of the program tools used is Integrated Flood Analysis System (IFAS) version 1.3.0 for hydrological modeling and flood discharge analysis in Pasir Pengarayan River. The data was used in May 2012 is assumed as an analysis of floods data for May 2013. Satellite data for rainfall is used GSMaP_NRT Correction Method original and GSMaP_NRT correction Method (Type1) formula 2 in the form of hourly rainfall data. The parameters used to assess model accuracy are wave form error (Ew), volume error (Ev), and peak discharge error (Ep).

GSMap modeling, conditions May 01 - 06 May 2012 period, while initial condition after IFAS parameter is simulated, Ew, Ev, Ep and are 43,52%, -9,92% and -5,93% for original GSMaP_NRT. While the simulation results from GSMaP_NRT correction obtained 1.57%, 12.58%, 20.34% and 77%. Modeling GSMap Corrected method type formula 2, conditions May 01 - 06 May 2013 period, where the initial condition after IFAS parameter is simulated, Ew, Ev, and Ep are 43,528%, -9,925% and -5,938% for GSMaP_NRT Corrected. While simulation results from GSMaP_NRT correction method type 1 formula with 12 mm rainfall simulation obtained 0.004%, 7.706%, and 28.030%
