IDENTIFICATION OF GROUND WATER POTENTIAL ZONE USING GIS & REMOTE SENSING A CASE STUDY OF MORANG DISTRICT (BIRATNAGAR) NEPAL

Abstract

this study thematic maps are analysed to decide groundwater potential zones utilizing combination of RS and GIS tools. The parameters which are considered for distinguishing the ground water potential zone are topography, DEM, land cover, geomorphic units and lineament etc. Reasonable positions are allotted for every classification of these parameters. For the different geomorphic units, weight elements are chosen dependent on their capacity to store groundwater. This technique is done for the various layers and resultant layers are renamed. The groundwater potential zones are grouped into five classes like exceptionally poor, poor, moderate, great and incredible. The utilization of recommended approach is exhibited for Morang District. Nepal is considered as most extravagant in as far as accessible water assets. Its tremendous water assets if appropriately used can be greatest wellspring of national riches. Agriculture is spine of Nepalese economy with over 80% of provincial populace effectively occupied with agribusiness as a calling for their living. It is known that water system can assume impetus job in expanding farming profitability. Water system expands agriculture profitability and empowers to develop numerous harvests, decreases the danger of yield disappointment because of dry season and balances out the nourishment generation by limiting rainfall-instigated variance. Nepal has 26000 km2 of land which is cultivable, however, just 18000 km of land is irrigable. The present ground water improvement establishes just a little division of potential as it was. The condition is unused tremendous ground water potential is because of absence of profound analysis, lack of inspiration and sponsorships for farmers, lack of satisfactory supporting approaches from government. Using model of GIS and Remote Sensing, it has been discovered that the Morang area holds a decent measure of ground water assets, which can be used for the overall advancement. At present, the ground water use is far beneath the accessible sum limit. It appears that mostly the water extraction is just for gathering household needs. There is colossal degree for the administrative projects which can make condition for use of ground water resources to quicken the agribusiness efficiency and industrial growth. The open water supply and sanitation offices can be improved and increases with appropriate management of water resources.
