Qualitative Performance of Different Soil and Water Conservation Measures at Shevadi-Yenoli Watershed

The research study on, ‘Impact evaluation of Shevadi-Yenoli watershed development in Parbhani dist. of Maharashtra’ was carried out during the year 2019-20 at Shevadi village Jintur taluka. The Shevadi-Yenoli watershed development programme was implemented by Agriculture Department of Maharashtra Government of Jintur Tahasil, dist. Parbhani under integrated watershed management programme, funded by NHM/EGS. Shevadi-Yenoli watershed (1772.76 ha) was developed by Department of Agriculture, Government of Maharashtra. Different soil and water conservation structures i.e., continuous contour trenches, loose boulder structures, earthen embankment were undertaken in the watershed. The present dimension of the structures i.e., top width, bottom width and depth were measured with the help of measuring tape and compared with designed dimensions. Data of designed dimensions of structures were collected from office of TAO, department of agriculture, Jintur, dist. Parbhani. The area of silt deposited was measured. Volume of silt deposited was determined by multiplying the silt deposited area and depth of silt deposited. Weight of silt deposited was calculated by multiplying the volume of deposited silt to the bulk density of silt. The bulk density of silt was considered for calculation purpose as 1.30 gm/cc. Based on the results obtained next conclusions were drawn it was found that the cross-sectional area of CCT, EE, LBS, reduced by 29.35–35.00, 12.94-19.23, 13.69-20.96 percent. The storage capacity of CCT, EE, LBS was reduced by 32.34, 16.20, 16.18 percent due to the deposition of silt over the period of four years after construction.
