Canal gauging Study 2. Seepage losses by Inflow- Outflow Method in Main course 3. Seepage losses by Ponding Method in Branch Watercourse 1. Canal Gauging study OBJECTIVE The main objective of conducting Canal Gauging study is to find the carrying capacity of the canal. • As per guidelines of CWC, 10 % of the total length of main canals, distributaries and minors were selected. • Project the study was carried out for 2 times in the crop season. The criteria for selection of representatives of study area are shown in below: ❖No weed growth ❖ No curvatures ❖ No drawers ❖ Regular section ❖ weed and silt should be removed at least 10m on both sides of the selected point VELOCITY MEASUREMENTS BY CURRENT METER ❖ Wading (When depth and Velocity Permits) method VELOCITY MEASUREMENTS BY CURRENT METER ❖ Measurement through Boat VELOCITY MEASUREMENTS BY CURRENT METER ❖ Measurement with a support of Bridge VELOCITY MEASUREMENTS BY CURRENT METER ❖ Procedure: Measure the width of the water surface and divide the stream into number of verticals/compartments VELOCITY MEASUREMENTS BY CURRENT METER Measuring Depth Across the section Spin Checking Positioning the Current meter Counter Setting Status of Canal Gauging Studies for 10 projects S.No Name of the Status of the study in Status of the study in Project 2016-17 2017-18 1 Rallapadu No Water in the Reservoir No water in the Reservoir 2 Peddavagu Completed Completed 3 Guntur Channel Completed Completed 4 Sathnala Completed Completed 5 Musi Completed Completed 6 Vattivagu Completed Completed 7 Vengalarayasagar Completed Completed 8 Thatipudi Completed Completed 9 Torrigadda Completed Completed 10 Thaliperu Completed Completed 2.Seepage losses study using Inflow-Outflow Method ❖ Seepage losses are calculated by measuring the inflow, outflow and evaporation losses of each selected canal segment. ❖ Seepage losses = Inflow-Outflow-Evaporation losses 3.Seepage losses study using Ponding Method ❖Method of bund formation Measuring water depths and water surface widths Status of Seepage Study for 10 Projects S.No Name of the Project Status of the study 1 Rallapadu Completed 2 Guntur Channel Completed 3 Vengalarayasagar Completed 4 Thatipudi Completed 5 Torrigadda Completed 6 Musi Completed 7 Vattivagu Completed 8 Sathnala Completed 9 Peddavagu Completed 10 Thaliperu Completed On-Farm Application Efficiency Infiltration study Objective: The main objective of using Infiltrometer is to measure the rate of water infiltrated into soil or other porous media.
