Increasing demands on water resources to ful ll the growing population needs have led to a great pressure on the water resources. Water resources conservation and management needs exemplary information regarding the water bodies with respect to quality, quantity and the related driving factors responsible for deterioration and depletion of water. Traditional methods existing in literature are limited to the point locations and manually gathered input dataset for analysis of the water system. However, after the development of advance geospatial technologies, now it is possible to build the digital information that can support analysis and interpretation for a large area in short span of time. e chapter introduces the various geospatial technologies, which are playing a vital and inevitable role in the acquisition of information and development of research capabilities towards water resources. ese technologies are required for determining a strategic plan for execution of desired results as applicable to dierent regions and objectives (for e.g. determination of water-river boundaries, water quality and quantity, soil moisture, ood plains, ocean temperature etc). is chapter provides dierent methods/applications to demonstrate the importance of traditional and advanced concepts of geospatial technology in water resources. us, overall goalof this chapter is to provide a summary of dierent research work carried out in various elds of water resources with demonstrated results and ndings that could be able to use in decisionmaking, developing policy and planning at root level. is chapter also provides future challenges in water resources andgeospatial technology. © 2017 by Taylor & Francis Group.
