Central Ground Water Board, undertake special projects in representative
areas of diverse hydrogeological hydrological and socio-economic setting for carrying out
water balance studies to determine the quantitative and qualitative aspects of ground
water potential with a view to planning on sound scientific lines, its long term
development and Management. Two such special projects have been completed in Madhya
Pradesh.
Narmada river Basin
Project (1971-75):
The project covered an
area of 29785 sq.km of the Narmada river basin of which 25900 sq.kms falls in Madhya
Pradesh and 3885 sq. kms falls in Gujarat. The main objectives of the project were to
establish the surface and ground water systems of a closed basin with an out fall area
close to the sea and possibilities of assessing the advancement of water front as a sequel
to the development of the coastal fresh water front. It also includes identification of
areas for experimental study of artificial recharge, which were applied as part of the
programme. The work proved the availability of 1029 MCM of replenishable resources still
available for further development through construction of 1640 shallow and 1175 deep
tubewells. In the out fall area of Gujarat it was seen that the development of resource
has reached near optimum limit and any further strain on the system is likely to result in
the landward movement of saline water wedge near the coast.
Upper Betwa river
basin Project (1975-79):
The project covered an
area of about 20600 sq. kms lying in Madhya Pradesh and Uttar Pradesh. The objectives of
the project were basin wise hydrogeological investigation for water resource evaluation,
preparation of ground water system and development of suitable techniques of
investigation, which could be applied in similar areas. Photogeological and remote sensing
techniques were also used to prepare mosaic of the study area and to prepare map of
geomorphological features and fracture zones that control occurrence and movement of
ground water in hard rock area. Sites selected for borewell with the help of this
technique near the fractures and lineaments proved to be successful. The work has poved
that 22500 dugwells/dug-cum-bore wells/shallow tubewells can be constructed in the shallow
aquifer zone, which will create an additional irrigation potential of 27000 hectares in
the study area. The deep aquifers are found to be limited in extent and of poor potential.
