Abstract

PLTGU Muara Tawar is one of the power plants that use sea water as a coolant. The sea water is channeled through the intake canal where sediments in it will affect the water supply. For maintaining the water supply in intake canal it is necesssary to have an information about sediment area and volume. This study schemes are to determine the drying height at lowest low water, sediment distribution, changes in sediment area, critical depth condition, and changes in the volume and sediment beetween March 2013 and December 2014. The data used are the position of the sediment surface and the tide height on March to April 2013 and Desember 2014. It is obtained that for safety requirements the water supply left only 32,75% in 2013 and reduced to 32,69% in 2014. So, to achieve the safety requirements of water supply in 2013 and 2014 the sediment ought to be dredged more than 60% from 6 meter below MSL base.
