Integration of GIS, improved entropy and improved catastrophe methods for evaluating suitable locations for well drilling in arid and semi-arid plains

In arid and semi-arid regions, groundwater plays an important role in both local economic and population development. Therefore, the cost effective and rapid assessment of locations that are suitable for well drilling is crucial. In this study, the improved entropy method and the improved catastroph...
