Model of settlement environment for flood prone areas on the bank of Cimanuk river Garut

Abstract

Settlements along the river are dwellings that are vulnerable to flooding. It is not easy to move residents from the area because of the strategic and economic value of the area for urban residents. The purpose of this study is to find solutions for flood-prone areas by making settlement plans to minimize the impact of flood disasters. The study was conducted in Rw. 10 and Rw.19 in Cimacan, Haurpanggung Village, Tarogong Kidul District, Garut Regency. Research data were collected using the interview survey method. To get a history of floods that have been experienced by residents, a questionnaire was used with the snowball method. Respondents taken were 22 respondents who had lived in 2 RWs for at least 5 years. Based on the results of the study note the average flood height of 40-50 cm with the distance of water entering the settlement 50-60 meters from the river bank. The average number of houses submerged by floods is 40-50. To minimize the impact of losses from flood disasters, it is necessary to re-arrange the settlement space in Cimacan Village by setting green land in the no-go zone for building settlements, making infiltration wells, and modifying house building models.
