Abstract: The Lower Citanduy Irrigation Project in Central Java, Indonesia, drains through the estuary called Segara Anakan. Due to sediment accretion, the lagoon is filling. With erosion problems, the rate of filling has increased. The filling has caused flooding and drainage problems in the irrigation area. For the irrigation project to function as designed, the drainage problem must be solved. The Government of Indonesia also wants to save the estuary for the fishing industry. These objectives were the purpose of the Segara Anakan Optimum Use and Drainage Study. The study was conducted using the USGS hydrodynamic model BRANCH. The study investigated conventional and agitation dredging, flushing and other structural solutions.
