Abstract: Trapping of sediments in rivers is done by various methods as is is tedious job; But still many researches have shown different techniques. By using artificial obstacles for collection of trap we can minimize transfer and deposition of trap in our reservoir. Along with obstacles some river training works found to be useful for collection and deposition of trap at particular location so that it will not get transferred close to the dam site. This research suggests the experiment analysis of trap collection in the river channel prior to dam site. Perennial rivers in which there is no chance to collect or remove the trap in dry period. It is quite possible for seasonal rivers therefore collection of trap in wet season and removal of it in dry season is quite possible in most of the states of India. Reservoir sedimentation has become one of the major problems facing water resources development projects in many countries around the world. However, only a limited number of studies has been reported in this field, particularly addressing the trap efficiency of reservoirs. The most important practical and critical problem related to the performance of reservoirs is the estimation of storage capacity loss due to sedimentation process.. A small-scaled laboratory model was set-up in representing a reservoir and a series of tests were conducted by varying inflow rate, inflow sediment concentration, reservoir capacity and outflow rate. The experimental results were compared with the available theories
