Rainfall-runoff Analysis Using Satellite Data in The Majalaya Watershed
Keywords:
satellite data, GSMaP, AWLR, water level, majalayaAbstract
Majalaya is a flood-prone area with a minimum of six flood events every year. There have been several efforts made by the government and residents for flood prevention and early warning efforts. One of them is the AWLR which was built to monitor the water level of the Upper Citarum River. However, the results of the recording of the AWLR itself are still in doubt because of the difference between the AWLR data and the observations of residents. Using the 2018 flood incident data as a reference, the hydrological analysis in this study was conducted by combining ground data and satellite data using the HEC-HMS application. The results of the modeling show that the difference between ground data and satellite data is quite significant. This is one of the validations of an error in the AWLR recording so that it gives different results.
