A flume experiment study of energy lose at downstream of a sluice gate

Abstract

Abstract A sluice gate is a controllable barrier that controlling the elevation of the water at the channel. Generally, energy change occurs at the upstream and downstream of watergate, caused by the impact of the water flow at watergate upstream. This study aims to analyze the energy change at Watergate and to compare the value of energy change that occurs at the channel with or without sediment. This research was carried out by the Civil Engineering Hydraulics Laboratory of the Faculty of Engineering, Hasanuddin University, which runs from December 2018 to March 2019. In this research, we use some variables that are channel bed condition, flume slope, debit, and watergate openings. The result of this research shows that debit and watergate openings really affect the value of the energy change, while the flume slope is not really affected it. The energy change that occurs at the flume without sediment is bigger than the energy change that occurs at the flume with sediment in it.
