Review on the Groundwater Potential Evaluation Based on Remote Sensing Technology

Groundwater is an important water resource, and plays an important role in people's life and production. The evaluation of groundwater potential is the prerequisite and basis of groundwater development and utilization. Compered to geophysical prospecting, drilling and other traditional groundwater evaluation method, remote sensing technology is an advanced monitoring method with time-saving, economize labour and highly efficient. Remote sensing technology can obtain the related information about groundwater potential with wide range, rapid and objective characteristic, and is an improvement and effective complement of the traditional methods. Based on the analysis of the current research status of remote sensing technology, this paper summarizes the method of groundwater potential evaluation by remote sensing technology, and analyses the advantages and disadvantages of various methods, and points out the research topic and development direction of the method.
