Variographic Analysis of the Electrical Structure of South Indian Unsaturated ZoneDescargar trabajo en formato PDF
The unsaturated zone is extremely important for the estimation of groundwater potential, but at the same time it is a complex medium to characterize, to understand the processes taking place and to quantify the flow through it. Therefore, the problem is addressed through an integrated approach. Although a large number of parameters from various processes play a role in recharge, the present work has been concerned with moisture content and resistivity in a vertical profile measured repeatedly using Neutron Probe and Time-Lapse Electrical Resistivity Tomography (TLERT), respectively. The time interval has been taken not uniformly, but as a function of the rainfall event. A unique application of Geostatistics has been made to bring the two different types of datasets onto a common platform. The application of geostatistics has also helped to analyses the spatial and temporal variability of these parameters, which helps to understand their contribution and the uncertainty involved.
