Comprehensive Evaluation of Drainage Channels Along Selected Roads in Medan City, North Sumatra

Abstract

Population growth has led to an increase in the discharge of runoff and domestic wastewater being channeled into drainage channels. This study aimed to evaluate the drainage volume on Jalan Taud, Medan City, and whether it can accommodate wastewater for the next 50 years. The observed channel started from the boarding house (Jalan Taud No. 112) to the Gulo Pangkas business unit (Jalan Taud No. 16), with a length of 1,000 m. This evaluation considered using population growth, wastewater discharge, runoff discharge, sediment generation, and evapotranspiration processes as part of the water cycle. The investigation showed that the current volume of drainage on Taud Street can still serve the community until 2047. Routine management efforts are needed, such as regular cleaning of the channel from garbage and sediment and also socialization to the community, to making the drainage can function properly.
