Jaisalmer, India: The Indian state of Rajasthan is working to map the groundwater level through GIS. The data would help one to trace the entire history of groundwater in an area. The European Commission, with the help of a state partnership programme and 26 experts of Rolta India, a firm which offers GIS solutions, will complete the pilot project in Rajasthan this December.
Surendra Nath Das, an expert on groundwater resources at Rolta India Limited, said the company has executed a project ”Aquifer Mapping” in Rajasthan and created village-level database for assessment of village-wise groundwater potential using GIS.
The firm has developed a GIS-based web application ”Groundwater Information System” which will be able to provide information on groundwater availability in each village and its suitability for human, cattle and agricultural consumption.
The website will be available both in Hindi and English, and will be launched on or before December 31, 2012.
Chief engineer, underground water department, Hansraj Bhatt said there are nearly 7,000 wells in Rajasthan and the department keeps a tab on the increase and decrease of water level by studying these wells. Now, with modern technique this work would become easy, he said
Apart from this, the population of village, geographical conditions, facility of school among other important information will also be available along with the information on groundwater.
Senior groundwater scientist N D Inkhia said evaluation of groundwater till date has been done through old means in the state. Even today, the level of water is measured using tape. The selection of place for setting up a hand pump or a tube well is still done by using old maps. As a result, the room for error is big.
Here in, the modern GIS technique will provide accurate information on groundwater level.
As part of the project, the data from state groundwater department and Central groundwater board, well location, its depth and water level will be digitised. Along with available tube wells in the state, data on quality of water and rocks will be digitized.
Using these inputs, the groundwater map will be prepared. All work is being done using latest software.
