Assessment of Irrigation Water Loss and Water Balance in the Thenpennaiyaru Basin of Tamil Nadu, India

This study employed a comprehensive technique for the systematic estimate of water balance in Thenpennaiyaru river basin irrigation systems (TRB-IS) Tamil Nadu, India. KRP reservoir and Sathanur TRB are primary sources area. We computed actual loss open canals (e.g., leakage evaporation). A provides accounting various system volume inputs abstraction, imported water, owing to precipitation or surface runoff), authorized consumptions, losses intermediate reservoirs. The proposed methodology enables evaluation components evaporation losses, unauthorized uses, metering errors, leakage, discharges) calculation performance indicators that enable identification most significant problems provide guidance managing losses. approach is evaluated implemented using hybrid system. Results indicate discharges canal account over half total loss, followed by problems. These findings emphasize need enhance everyday operation these restore their infrastructures.
