Quantitative Assessment of Regenerated Flows for Irrigation Management in a command

India is an agrarian country uses its major portion of surface and groundwater resource for irrigation. The losses through conveyance and application are the major losses in irrigation and a significant portion of supplied water from reservoir may emerge in the downstream of river called regenerated flow. The computation of regenerated flow coming out of command in the form of surface water is useful for Water Resource Department for assessment of water availability in downstream projects. Presently in Madhya Pradesh state, a fixed 10% of water storage is used as regenerated flow from command which needs to be verified using scientific assessment for optimal utilization. In the present study, a simple water balance of different components of the hydrological process has been carried out to compute regenerated flow and its percentage in Sanjay Sagar Command situated on Bah river in Madhya Pradesh. The Sanjay Sagar project has a reservoir by constructing a dam (Construction Year: 2014) on river Bah with the gross storage capacity of 86.40 MCM and 9398 ha wheat in the command. In hard rock areas of Madhya Pradesh, surface runoff and horizontal flow are more predominant in irrigation and can be computed by field observation and measurement. In the study, daily flows from the reservoir for irrigation, crop water requirement and river flow downstream of the reservoir on Bah river from the year 2015 to 2018 have been analyzed in a water balance model to compute regenerated flows due to irrigation in the command. The computed regenerated flows in different years found 24 to 33% which is more than the amount fixed for computation of flows to downstream reservoirs in Madhya Pradesh.
