Analysis and interpretation of groundwater contamination using remote sensing and GIS :A case study

Abstract

Water is the most ubiquitous material in nature and is the most vital and fascinating of all God's creation. It is the most important raw material for mankind and is called "Liquid Gold". It is mainly because of this magical substance only that earth's temperature is maintained reasonably uniform at an average of 16 °C. Without water its temperature would have varied as on moon where it is 100°C during days and-130°C during nights. Man can

Using Remote Sensing to Map and Monitor Water Resources in Arid and Semiarid Regions

“…For example, Asadi et al [1] have performed a model study for sites in the Hyderabad and other districts of India, which identifies groundwater potential zones using IRS-ID PAN and LISS-III satellite geocoded data on a 1:50,000 scale. The information from base maps, drainage maps, watershed maps, geomorphology maps, groundwater table maps, and groundwater infiltration maps were used as data layers in a GIS to prepare a database.…”

“…Water shortage in arid regions can be further aggravated by the global climate change that is predicted to severely impact these regions. Thus, exploration, mapping, and monitoring of water resources are a prerequisite for the availability, accessibility, fair utilization, and rational management of water resources in arid and semiarid regions [1][2][3].…”
