One of the most grippping and intensly scientific presentation at WHSC has been this one, by
Prof. P.S. Datta
The concerns of resource managers, according to Prof. Datta are :
From the day's line up of speakers, we have people presenting on all the above concerns. From the above list , evaluating water quality, its degradation causes and identifying ground water flow pathways of inter-mixing can be
The concept is based on the fact that water acquires specific signatures, (in the form of isotopes) and so referred to as "isotopic fingerprints" when water changes its phase (like evaporation) or when different masses of water mixes together. These isotopes thus formed are the signatures which could reveal the entire course of events about the water.
And hence, it was appropriately said that, "Water memorises its origin and path".
For detailed explaination and experimental data, I highly suggest to download the
This novel approach, in applying nuclear research to ground water studies is the basis of the (now famous) ground water depletion images of north India published by GRACE, NASA group. See the images on this post.
