AQUIFER STUDIES

We conduct hydrogeological studies to determine groundwater parameters by conducting pumping tests on dug / bore / tube wells and analysis of pumping test data.

Aquifer studies includes aquifer modeling, determination of aquifer characteristics and types, aquifer size/location and depth, groundwater quality and hydrochemistry, abstraction patterns and aquifer depletion, groundwater recharge, saline water intrusion, aquifer contamination etc.aquifer

Aquifer Tests
Hydrogeological studies include determination of aquifer parameters by conducting pumping tests on dug / bore / tube wells and analysis of pumping test data.

Important aquifer parameters are:

  1. Porosity :measure of void space in the rock formations. It is defined in percentage as the ratio of the void pore space to the total volume of the rock formation sampled.
  2. Hydraulic conductivity : rate of flow under a unit hydraulic gradient through a unit cross-sectional area of aquifer. The unit is in m/ day.
  3.  Transmissivity : rate of flow of groundwater under a unit hydraulic gradient through an aquifer of unit width and unit thickness. That is, transmissivity is the product of hydraulic conductivity and thickness of the aquifer. The unit is in m2/day.
  4.  Storativity or storage coefficient, applicable for confined aquifers : volume of water released from storage per unit surface area of a confined aquifer per unit decline in hydraulic head. It is dimensionless.
  5.  Specific yield, applicable for unconfined aquifers : volume of water released from storage under gravity by an unconfined aquifer per unit surface area of aquifer per unit decline of the water table. Specific yield is dimensionless or can be given in %.
  6.  Specific capacity of a well : ratio of discharge of the well to the drawdown, in m3/hour/m.

Hydrogeological input also comprises the study of unsaturated zone. This includes micro-level studies at selected sites and areas as well as utilizing the information on unsaturated zone obtained from remote sensing study and geophysical measurements.
