Book Chapter Description

Most of the world's freshwater resources are known as groundwater. In just a few areas, increased groundwater depletion causes significant consequences for a water table fall, water quality deterioration, stream base flow loss, etc. Water resources, especially in developing countries, are poorly controlled and hydrologically educated offer valuable metrics for groundwater resources recognition. This chapter explains the capabilities of various satellite sensors to derive specific primary and secondary parameters associated with soil water studies. Different spatial models have been studied to demonstrate how spectral indices, digital elevation models (DEM) and their potential as passive, low-cost investigation techniques for groundwater studies are. Possible application of space technology in assessment, monitoring, and use of groundwater resources was established. This chapter also explains the specific problems and challenges associated with space and groundwater study. Also possible potentials of groundwater space technology are briefly summarized.
