Abstract

West Denpasar District is a densely populated area with 206,958 people. One of the environmental problems that occur is the frequent occurrence of floods due to the increase in residential areas. One way to overcome this is to build infiltration wells to reduce flood risk, reducing flood volume and discharge. The methods used are descriptive and quantitative. The analysis is carried out by describing the conditions of the study site, then continues with mapping analysis, hydrological analysis, infiltration well analysis, and effectiveness analysis. The analysis results stated that the peak discharge of the 50-year-old flood at the study site was 268. 90 m3/sec. Furthermore, the results of the planning analysis of the application of infiltration wells carried out in the West Denpasar District area, which is included in the Badung River Basin, can reduce flood discharge up to 41. 25%, and for flood runoff, volumes up to 51. 38%. Based on these results, it can be interpreted that infiltration wells have a role in reducing the risk of flood disasters in the West Denpasar District.

Abstract

The hydrological component is the main component in planning water infrastructure. The quality and quantity of rainfall data recorded at each rain post is the most crucial component in hydrological analysis, so it is necessary to analyze the rationalization of the rain station network to obtain an effective and efficient one. This research was conducted in the Tukad Mati Watershed, which has an area of 44,667 km2, with the length of the main river reaching 22,429 km, and there are six rain stations spread across the watershed. Rationalization analysis was carried out using two methods, namely the WMO (World Meteorological Organization) and Kagan-Rodda methods. The analysis using the WMO standard found that all rain stations were less than the minimum density. Meanwhile, from the results of the analysis using the Kagan-Rodda method with a smoothing error (Z1) of 9.069% and an interpolation error (Z3) of 7.989%, it is recommended that four selected rain stations out of six rain stations, namely Ngurah rain station, Sanglah rain station, Sading rain station, and Kapal rain station.
