Abstract

The Belanti I lowland irrigation area is a lowland development area built in the 1980s through the Tidal Rice Field Development Project (P4S). Currently, the land functioned for agriculture is only 1.211 hectares out of 3.392 hectares. These conditions are caused by unfulfilled water and soil quality requirement in that area, so many of the areas are abandoned by farmers. Siltation occurs at several channel points, especially in the reservoir (kolampasang) that is filled with sediment and overgrown shrubs. Kolampasang siltation will certainly cause water flow dynamics in the main channel, so the issues are interesting to be studied. The methods used in this study were based on field observation to verify the existing data. In addition, HEC-RAS hydraulic analysis simulation will be adopted to obtain channel water dynamics using geometric and boundaries data of Belanti I Lowland Irrigation Area. Based on the results of the HEC-RAS simulation, it is found that the presence of a kolampasang will affect the water level, velocity, and discharge in the main channel of Belanti I Lowland Irrigation Area, so that the hydraulic performance of the channel is optimal.
