ABSTRACT: <br /> <br /> <br /> <br /> <br /> Tambak Pandu in North of Kabupaten Karawang, which was developed in 1984, was one of Government effort to increase non-oil and gas export. With the total area 250 ha, it is supplied fresh water from Ciwadas Barrage and salt water from Salt Water Intake Canal (SWIC). The length of SWIC is 1.500 m straight to the sea and 100 m width, which was constructed by jetty. The construction of SWIC is intended to get clear salt water, because the salt water through 1.000 m width from the shore line is high turbidity. The construction of SWIC caused the change of shore line. The shore line in the right side of SWIC goes forward and the up set down with the other side. It caused the unclear salt water enter the SWIC and leaving the sedimentation problem there. Until 1997, the sedimentation problem was solved by using dredger ship, but it was costly. Using the discharge from Ciwadas Barrage, it was studied to flush sedimentation by using HEC-RAS 4.0 Beta. The model simulation presented that flushing was possible in SWIC by fulfill the criteria i.e. the width of SWIC must be 10 m. Total sediment in 11 months could be flushed during 15 days with 6 hours activities per day.
