ABSTRACT

 

The present study is to examine the potential for water harvesting and conservation of ground water against drought in Mithri watershed lying in semi arid tracts in Pali district of Western Rajasthan (India). Climate data analysis of forty years (1969-2008) has to know the trends of temperature and rainfall. Average annual rainfall is 495.8 mm and it shows a decrease of 141 mm in the past fourty years. Maximum and minimum temperature recorded is 45.5° C and 0°C respectively. General slope of the watershed is from SE to NW and varies from 0-90° at gradients of 12 feet/ mile whereas general elevation is 320m above mean sea level. IRS LISS III data have been used to prepare thematic maps through visual interpretation. Secondary data was used to prepare maps of drainage, geology, geomorphology etc. Thematic maps were superimposed in Arc View GIS 3.2 for Overlay analysis of various parameters such as drainage, geology, geomorphology, and slope has been attempted in GIS domain to bring out the interrelationship among them.
