Coastal groundwater dynamics and management in the Saurashtra region, Gujarat
National Institute of Hydrology, Roorkee in collaboration with Gujarat Water Resource Development Corporation
 
Objectives
 
Groundwater is becoming more and more depleted as demands from irrigation, a growing population and industry take more and more from aquifers. The ambitious study aimed study a coastal aquifer in the Saurashtra region to amongst other things:

The study set out to:
  1. Characterise the various hydrological components and establish their quantitative inter-relationships.
  2. To identify the causes of increased salinity in groundwater.
  3. To examine the possibility of mixing freshwater with saline groundwater.
  4. To examine the socio-economic impacts of saline water intrusion.
  5. Study trends and to investigate potential changes resulting from climate change.
 
Results and Recommendations
 
  1. A significant body of historical data was collected.
  2. Water levels and chemistry were collected from 114 monitoring points every two months, from open wells, piezometers and from streams, lakes and the sea.
  3. Groundwaters are saline all along the coastal region. Salinity decreases as one oves away from the coast due to rainfall recharge.
  4. Unfortunately at the time of writing (April 2014) no final report is available and hence no further details of results can be provided.
