Due to sedimentation, many nutrients, contaminated substances are transported, which ultimately reduces land productivity. Remote Sensing (RS) and Geographic Information System (GIS) used integrally to find sediment yield and morphological parameters responsible for causing soil erosion. SAGA-GIS (System for Automated Geo-Scientific Analysis-Geographic Information System) software version 6.3.2 utilized for editing spatial data, preparing thematic maps, statistical data analysis, etc. To know the spatial prediction of soil loss and risk potential of erosion, ULSE model (Universal Soil Loss Equation) was used. Watershed: 63 selected for research work which is located in middle sub-basin of Narmada river. It is sited in Narmada district of Gujarat and Nan durbar district of Maharashtra. The Shuttle Radar Topographic Mission (SRTM) data employed for preparation of Digital Elevation Model (DEM) and to prepare slope maps. The results showed that study area comes under severe soil erosion class i.e. 47.79 Ton/ha/year and high sediment yield achieved as 19.14 tons/year. This is due to existence of moderate to steep slope, moderate land use practices, moderate drainage texture. This study will prove to be helpful in watershed management strategies and to conserve the natural resources according to priorities.

Remote sensing data provide compact information to evaluate the sedimentation yield in the reservoirs by deriving several surface parameters. SAGA (System for Automated Geo-Scientific Analysis) GIS software with version 6.3.2 used and was used for preparation of maps and to verify the spatial extent of the area. The value of soil loss can be determined by using predictive model known as RUSLE (Revised Universal Soil Loss Equation) model approaches. The study area selected for present study is watershed no-63 of Narmada river lying in Narmada river watershed situated in two different districts , one of them is Narmada district located in Gujarat and Nan durbar district located in Maharashtra. Integration of results obtained from satellite data show Watershed no: 63 comes under very high soil erosion class i.e.33.12 Ton/ha/year (By RUSLE approach) indicating a moderate to steep slope exist in such area and sustainable moderate land use practices in that particular catchment.

The aim of this study is to use GIS technique and remote sensing data integrally which will show how morphometry parameters are responsible for causing sedimentation by extracting river basin, stream networks and analyzing such parameters through Shuttle Radar Topographic Mission (SRTM), Digital Elevation Model (DEM). SAGA (System for Automated Geo-Scientific Analysis) GIS software with version 6.3.2 used for preparation of maps and to verify the spatial extent of area. Watershed number-63 of Narmada river is selected for research work which is lying in middle Narmada river basin, situated in two districts, Narmada district of Gujarat and Nan durbar district of Maharashtra. The watershed contains 2 sub-watersheds. Integral results obtained from satellite data and GIS technique shows that study area comes under very high to severe soil erosion class because moderate to steep slope, moderate land use, homogeneity in basin texture, lack or moderate structural control exists. The study concludes that morphometric analysis along with GIS technique proves to be very helpful to identify the geo-hydrological, geomorphological characteristics of basin for planning, sustainable development and management of watershed.
