Surface Runoff Control in Bandung Regency with Infiltration Wells Through Remote Sensing Analysis
Last modified: 2022-11-15
Abstract
This study aims to control surface runoff on the smallest land unit and the distribution of infiltration wells to accommodate the volume of rainfall in Bandung Regency. Experimental research method using Landsat 8 OLI imagery in 2020. The samples analyzed were based on built-up land in each watershed. The results of satellite imagery analysis show that the built up land in the Ci Widey watershed is 23.36 km2 and the volume of rainfall and runoff is 680,243 m3, Ci Sangkuy 20.05 km2 and the volume is 583,860 m3, Ci Rasea 11.74 km2 and the volume is 1258,275 m3, and Ci Tarik is 68.59 km2 and the volume is 1997,340 m3. The built-up area is 100 m2, the rainfall volume is 2,912 m3 and the lowest is 0.284 m3, so the distribution of the number of infiltration wells is Ci Widey 340, Ci Sangkuy 292, Ci Rasea 629 and Ci Tarik 999. By controlling the runoff according to the volume of rainfall on the built-up land and entering it into infiltration wells, the rainfall does not have the potential to become runoff.
