Flood Water Level Modeling In Bukit Tiara Residential
Main Article Content
Abstract
Flood is a natural phenomenon that can threaten the existence of human life, especially during the rainy season. Bukit Tiara Residential, which has a land area of ± 282 hectares in Kecamatan Cikupa, Kabupaten Tangerang, plans to develop its area. To get a building elevation that is safe against flooding, a flood water level modeling study was carried out in Bukit Tiara Residential. In this study, the analysis carried out is the calculation of planned rainfall, choosing the type of rain distribution, calculating the time of concentration, determining the amount of rain intensity, calculating flood discharge and modeling the water level using the HEC-RAS program. From the results of the analysis and calculations, it is known that there is a need for land exaltation in several areas so that the planned land elevation is safe from the threat of flooding.
