Effective management of water in an irrigation system requires knowledge of the quantity of water flowing in the canal in order to send the appropriate quantity of water to every consumer at the right time, avoid unnecessary losses, and avoid physical and environmental damages. Seepage outflow from canals affects the efficient operation of the canal system as this water leaves the canal, moving downhill and through the soil strata, and may no longer be directly available to the water consumers. Also, seepage affects the effective water management basis because it sometimes produces erosion and piping damage at control structures. Canals continue to be major navigation systems for delivering water for irrigation. The seepage loss from irrigation canals constitutes a considerable percentage of the usable water. The loss of water by seepage from unlined canals in India varies from 0.3 to 7.0 m3/s per 106 m2 of wetted surface. The seepage loss from canals is ruled by hydraulic conductivity of the subsoils, canal geometry, location of the water table relative to the canal, and several other factors. We will be doing estimation of seepage losses in the Nira Deoghar canal. The canal seepage section that I will measure is of 7 km length. For this project Nira Deoghar projects right bank canal is selected for measuring discharge and find out the seepage losses. We will measure the water depth and calculated the difference between the levels and find out seepage loss in lined and unlined canal. The inflow-outflow method used to measure seepage, in which area and velocities will be measured under steady flow conditions will be considered. We will calculate discharge and seepage loss by using Direct method. As a result, reaches the highest seepage losses will be identified and how major seepage loss can be prevented by using HDPE sheet will be computed. Hence, the study of canal lining and the seepage taking place must be computed. A comparative study will be done on the lined, unlined and the lined canal with HDPE sheet to conclude the project. And further from the wasted seepage water how can crop(rice and wheat) yield be harvested will be hence computed.
