Geophysical Characterization of Salinity Ingress in Surka Mining Lease Area of Gujarat, India

Posted on

Salinity ingress is one of the most vulnerable environmental risks of coastal area on account of several significant factors. It depends upon local lithology, geomorphology, hydrogeology and land use from terrain characteristics point of view. Economically, the coastal area has attraction for human settlement and related activities pertaining to industry and agriculture. The main environmental risk is the unbearable limit of chloride content as quality parameter among the existing ground water body and its continuous threat for newer horizon. The term salinity ingress may be defined as the objectionable entrance of undesired high content of chloride among the available ground water.

The researchers address this problem by advanced technology like mathematical, computer based methodology whose success strongly depends upon the quality extension and reliability of input data. In this sense, geophysical characterization plays an effective role for integrating the lithological and hydro-geological data, planning of drilling and ultimately gathering the information necessary for the modeling purpose. The geophysical characterization may be defined as the understanding and documenting the distinguished property of strata and its associated features like ground water by reliable instruments indirectly.
