Description

The study area i.e. Shetrunji basin falling in the district of Bhavanagar, Amreli and Junagadh, is a major one among 71 river basins of Saurashtra region of the Gujarat state, India. The major share of monsoon rainfall concentrated during July and August month. Therefore, the scope for the natural recharge is very less. The sediment load of the runoff water should be inevitably minimized by taking appropriate soil conservation measures under watershed development plan. Planning any soil and water conservation requires the complete knowledge and quantified indicators reflecting true hydrological behaviour of contributory watershed. Hydrological behaviour of any natural watershed or basin depends on its geomorphological characteristics which need to be assessed and quantified properly. The determination of the geomorphological characteristics of any watershed requires intensive survey, which is a tedious, difficult and time consuming activity if done by adopting traditional methods. Present study was undertaken adopting remote sensing and GIS technology to ease the task keeping with a view to explain the possibility of work.
