Application of GIS and remote sensing techniques for water resources management

Water is one of the most important natural elements on earth. Water quality directly and indirectly influences human lives and development. In this paper, a GIS-based system is designed to assist water resources professionals in making economical and efficient decision. GIS and remote sensing techniques are effectively used to replace, complement and supplement data collection in various facets of different kinds of water resources projects. This paper describes the design and implementation of a GIS-based system for water resources management. The system consists of five parts: Geographical Information System (GIS), the database, the mathematical model, the knowledge database and the user graphical interface. The system can help water resource manager to appreciate the potential of remote sensing capabilities for application in the management of precious water wealth. The system can dynamically monitor water and provide decision support for precious water management. It has obvious economic, environmental and social benefits.
