The Shivalik range of Himalayas, represent the most fragile ecosystem in India, in order to restore the ecological environment in this area, a hilly watershed typical of the region of 21 ha area was brought under study in 1963. The watershed has been under complex protection and was treated by soil and water conservation measures during 1963-64.
Direct measurement of soil erodibility, resistance offered by the soil to both detachment and transport processes, is not only costly but time consuming also. So, efforts have been made to predict it from the soil physical properties.
In foothills of Shiwaliks due to presence of torrents, soil erosion is very serious problem. The flow acquires accelerated velocity at it travels down the slope and consequently becomes highly erosive in nature. Study aea of Baroi Khad (rainy season torrents) lies at Akhnoor Tehsil of Jammu district in Jammu and Kashmir state.
Hill agriculture in India is confronted with the problem of uneven topography, soil erosion, small landholdings, inaccessibility with poor road infrastructure and opportunities of fertile land, high and dependable precipitation in the form of rain, snow and an agriculture friendly climate that can be the best bet for the development of watershed development programmes on a large scale.
An evaluation for the development work done in the two watersheds, viz. Bunga and Dabkauri in Panchkula District, Haryana was carried out for 2004 and 2007. Satellite digital data of LISS-IV sensor for 2004 and
This work reports an attempt to make use of the indigenously developed high resolution IRS-1C satellite imagery to generate a database, including expertize from different organizations involved in floral, soil, microbial, hydro, socio-economic and geological fields. In the absence of large scale topographic maps, high resolution precision geocoded PAN + LISS-III imageries at 1 : 12,500 were used.
The groundwater resources of India play a major role in the irrigated agriculture. Therefore, expansion of these resources to increase agricultural production received high priority in the development programmes of the country. The area under irrigation by groundwater through wells is continuously increasing. On the contrary, contribution of canals and other sources is decreasing.
Streo Cartosat-1 satellite data was processed to generate high spatial resolution digital elevation model (DEM) using ground control points (GCPs) collected through geodetic single frequency GPS in differential GPS mode. DEM was processed to generate bare earth DEM by removing heights of natural and man made features from DEM.
