Zonation of depth to water is helping in identifying shallow and deep water table areas, which is being used for demarcating areas for intercepting drain and suitable areas for horticulture where water level should be more than 2 mts below ground water. This also help in monitoring the behavior of water table over a period of time, and effect of tubewell on ground water region.

For the administrative point of view UPBSN has digitized all the Project Districts map which contains Tehsil and Block Boundary with their HQ location, Village Boundary of selected villages, all major Roads, Drains, and River etc. Details of Basin, Region, Catchement, Sub Catchement and Watershed features are also transferred from Watershed Atlas of India. On the basis of village base line data villages where Panchayat Bhawan and connecting roads are not developed/available are identify and marked on district map. To make effective impact on project monitoring & implementation circle plan of each project district has been prepared (Fig-5). In this plan each district divided into 3 Project Manager (PM) unit, and each PM unit has 5 Sub Units headed by Dy. Manager (DM) and each Sub Unit has 4 Circle posted Assistant Manager (AM). All field activities is closely supervised by AM.

Presently utility of GIS/RS is being used in following activities:
  • To identify location of specific village/area of interest, which satisfy suitable conditions for selection, based on specific parameters.
  • pre and post monsoon water level and fluctuation data; below ground level as well as with respect to mean sea level for defining spring level and flow direction.

  • Loose or close coupling with GIS of simulation models of salt movement in the soil profile and ground water column.
  • Zonation of Depth of Ground water and delineation of shallow water table area.
  • IRS LISS II/LISS III based project durability evaluation and integration with GIS.
  • Evaluation of land use changes, soil quality, GW level and quality reclamation over a period of time.
  • To locate suitable boring site and pumpset installation.
  • To existing drainage and canal status and future planning to drainage development.
  • To identify the catchement area of a drain.
  • Integration of spatial and non-spatial data
Present Setup

At present GIS setup is installed at HQ, equipped with PC Based Arc/Info, Arc View 3.1, PC TIN and Auto Cad 13 software which are running on Pentium 120/400 machines. A0 size digitizer and a Plotter is being used as an input and output device respectively. Two total stations are being used for survey work. Upgradation of GIS platform (NT based) is under process. Remote Sensing/Image processing services are being taken from U.P. Remote Sensing Application Center, Lucknow.

Some Issues:

Presently source maps (cadastral)on 1:4000, are being used, supplied by Dept. of Revenue. These maps are very old and have no projection system. UP RSAC has taken some initiative in this direction. Procurement of GPS under process which will be used to transfer cadastral level information to 1:5,000 scale map.

The task ahead:

Digitization of Cadastral maps (approx. 3000) and various other type of data related to Ground Water, Agriculture and Irrigation, which are available on record, would be computerized and transformed into GIS for the project use. Efforts are being made to tie up with Dept. of Revenue for digitization of cadastral maps.

UPBSN has a large MIS data for all the villages selected for reclamation, including village base line, beneficiary base line, plot wise soil analysis and post reclamation soil quality etc. integration of all relevant data would be the main objective of UPBSN.

Conclusion

Under the on going U.P. Sodic Land Project, Environmental Monitoring data can be integrated on GIS platform for analysis and Evaluation of sustainbility of reclamation Selection of project villages ,post reclamation monitoring and behavioral changes in Ground Water levels and quality .
