49-A Factor Analytic Model for Delineating Groundwater Source Areas.

Abstract

About 80% of the total water demand is being fulfilled by developing groundwater resources. For optimal sitting of groundwater developmental activities and sustained agricultural growth it is essential to assess the available resource. Resource evaluation by conventional methods is costly and time consuming. Data required for groundwater resource evaluation are not sufficient. When they are available their integration and decision making is difficult. In this study an attempt has been made to represent the groundwater potential system by a Factor Analytic Model (FAM). Input to the model has been given through synergistic use of remote sensing and ancillary data. The model can be used to delineate the groundwater source areas. In these areas detailed investigations can be carried out for optimal development of the available resources. The model compresses the data by 70% that makes the analysis simple.
