Evaluation of the Relationship between Water Discharge and Flow Speed on the Volume of Open Channel Sediment in the UKI Campus Area, Jakarta

Abstract

ABSTRACT

Open channels are a common type of channel and require special attention because they often undergo erosion and sedimentation processes. The erosion that occurs in open channels is affected by water discharge as well as flow speed. This study aims to determine the volume of eroded sediment in open channels within the Christian University of Indonesia. The research method uses a simulation approach to obtain an overview of conditions through a small-scale system. Observations were made on a 25-meter-long channel divided into five pias, resulting in six measurement points. The water discharge and flow speed are measured at each point using a current meter. Furthermore, at the sixth point, sediment is added to measure the volume of sediment that has eroded in a certain time span. The observation results show that the flow discharge (Qp) increases as the water level (h) in the channel increases. The larger the discharge that occurs, the greater the volume of sediment erosion that is formed.
