Details: detailed topographical & hydrographical survey of various river / khals / drainage channels / canal/ canals/ dam/ reservoirs/ beels etc using higher precision instruments like dgps /rtk /total station for land survey, adcp/eco-sounder for water body survey etc along with total geo-referencing (x-y-z) alignment and plotting on google earth /arcgis based map for taking cross section, long section of drainage channels/ khals/ rivers (extending each cross section up to 50m from toe of country side at both side bank) w.r.t. nearest known ground control point (g.c.p)/ great trigonometrical survey (gts)bench mark, including additional cross sections (both u/s & d/s) at the point of bridges, regulators, cross drain , inlets tributaries, branch channels, drains, out channels from pump houses , important structures etc. including additional cross sections at adjacent outfall point of these drainage channels /khals/ rivers into other river for 250 mtr u/s & 250 mtr d/s of that outfall point and s
