In the present paper, the performance evaluation of watershed management measures has been studied in Keshar sub-watershed using quantitative methods viz. double mass curve, moving average, discharge-duration curve and hydrologic regime analysis. To conduct the study, the daily precipitation and runoff data belonging to pre and post periods of implementation of measures i.e. 1996-1998 and 1998-2001 were collected. The double mass curve showed the positive effects of measures in runoff reduction. The reducing trend in runoff values was also verified by 5-days moving average. Studying the developed discharge-duration curve depicted the obvious reduction in high as well as low discharges and an extension in flow duration. Achieving a gradual slow in hydrologic response of the watershed was also confirmed with the help of hydrologic regime analysis. In overall the well performance of the implemented watershed management activities was quantitatively approved by applying the aforesaid techniques.
