Application of geospatial techniques in hydrological modelling

Abstract

Water management planners face considerable uncertainty in determining water availability, as change in global climate and land use/land cover patterns have altered hydrologic conditions and led to change in the dynamics of the water cycle. Therefore, it calls for having a better understanding of hydrologic processes and surface/groundwater dynamics in hydrologic and water resources management studies. The water budget analysis of a region can be done with the help of hydrological models and geospatial techniques. In the present chapter, applicability of geospatial techniques in hydrological modeling is described in detail.
