Aquifer Recharge

Title of the Project:
Development and management of groundwater resources in over exploited hard rock areas

Sustenance of groundwater for agriculture in hard rock granite terrene (Semi arid region) is of prime importance and further to the rural drinking water supply. Sustenance in time-domain is of two phases of groundwater management and accelerating the measures for meeting the continuous demand with dovetailing of replenishment of groundwater. Replenishment of groundwater through recharge processes of natural and secondary are vital in the wake of increase in dependency on groundwater and regional exploitation, which has resulted in continuous falling of groundwater levels and quality deterioration. Further, recharge studies are of greater significance in India, because of the extreme meteorological conditions of vagaries of monsoons and high potential evapotranspiration on one hand and inadequacy in runoff storage on the other. Therefore, new techniques are needed not only to measure the rate of replenishment, but also to conserve surface water and enhance groundwater recharge artificially at micro/macro levels.

Aims and objectives of the project study (2012 – 17)

  1. Development of alternate tracer other than tritium with limited laboratory and field support for moisture transport and recharge evaluation
  2. Moisture flux transfer and recharge under shallow, medium and deep water table conditions
  3. Impact evaluation of artificial recharge structures
  4. Bore hole Tracer techniques for evaluation of Dispersion coefficient and actual groundwater flow velocity
  5. Recharge and groundwater management studies in NGRI campus

Title of the Project: The Structure and dynamics of groundwater systems in northwestern India under past, present and future climates [GAP-663-28 (DWK)]
Mapping near surface alluvial and fluvial palaeochannel aquifer system of northwest India is of much concern in order to understand the groundwater dynamics and prospects within the alluvial plains of Punjab and Haryana where groundwater resource is considered at a greater risk. In the present work, 2D electrical resistivity tomography was accomplished in the northwestern India in order to continuously map the sand body and other major litho units with depth. The presence of buried channel (dry and hard sand formation) is well resolved from the 2D resistivity tomography model dataset. The discontinuity within the buried channel is clearly visible from the inverted 2D resistivity sections. These buried channels acts as a confining layer as well conduit for groundwater flow. These channels are hidden and are indicators of groundwater reserves and could be exploited – a precious resource as and when on demand and need.
