초록
The objective of this study was to evaluate the performance of selected sediment reduction methods to reduce sediment discharges from drain and irrigationof different types (concrete canals, soil canals). This study was carried out to analysis for the suspended sediment concentration and sediment of drain andirrigation by velocity of flow. The results of study were analysised and summerized as follow. Sedimentation characteristics and size of soil sediment fromthe concrete and soil canals of downstream smaller than upstream. Suspended sediment concentration and flow times from the suggestion canals biggerthan open canal. Structural shape of the canal decreases the velocity of flow also affects the suspended sediment concentration and flow times.
