Efektivitas Kolam Retensi Universitas Sumatera Utara dalam Mereduksi Banjir pada Jalan Dr. Mansyur Kota Medan dengan Storm Water Management Model 5.2

Abstract

A retention pond is a pond or reservoir that collects rainwater for a certain period of time that serves to cut off the peak of flooding that occurs in a drainage or river. In Medan City, there are several retention ponds in an effort to control floods, one of which is the University of North Sumatra Retention Pond. In 2023, the construction of the University of North Sumatra remembrance pond will be carried out to overcome problems that occur in the Medan City area. The purpose of this study is to determine the drainage condition of Jl. Dr. Mansyur which passes through the University of North Sumatra area after the existence of a retention pond. In this study, the data used is secondary data in the form of daily rainfall for 10 years. The results of the calculation of rainfall planned with a range of 10 years are 160.60 mm/hour. The next step is to conduct a simulation using SWMM 5.2 software to determine the effectiveness of the retention pool at the University of North Sumatra.
