Pakistan is an Agricultural Country and crops required water. The efficiency of the waterConveyance structure besides other parameters also depends on seepage losses. Due to itsImportance, it is an important component in the design of natural channels. As Pakistan will faceWater crises in near future, therefore there is need to conserve each and every drop of water.Due To its scarcity, water will become a very important commodity. A large number ofanalytical Equations are available in literature that needs to be assessed for a particular canal.In this Research Study seepage has been calculated for Pehur main canal located in SwabiDistrict of Khyber Pakhtunkhwa using 1) Field measurements, and 2) Four equation fromavailable Literature, 3) newly developed equation from the collected data. In this study forestimation of Seepage analysis, Discharge was measured in the field and the evaporation datawas obtained From Tarbela gauging Station. Using field data including discharge and othercanal parameters, Regression-based equation for seepage analysis is developed for thisparticular region. The Equation developed for the Estimation of seepage in this area is based onnot only geometrical And flow parameters but also on the soil properties because it is necessaryfor accurate Estimation of water losses in the Conveyance network. This equation is based on theinflow-Outflow discharge method and boundary Materials, and is valid for earthen canalshaving the Same geomorphology. Results showed that the Equation developed in this researchstudy Performed better than all other equation including Nazir Equation.
