Abstract
Aim The global need for water-conserving increasing in arid and semi-arid areas and water
preserving by improving vegetative cover in rangelands by reducing the erosion effects is a
rational justification for the performance of underground dams. This research aimed to locate
underground dams using GIS integrated with the fuzzy algorithm.
Materials & Methods The data layers included geology, LU/LC, streams, villages, water
resources, and slopes of the Sarakhs region, Iran, were prepared and standardized by the
sigmoidal membership function.
Findings Almost 98% of the final maps were in the fuzzy range of 0 to 0.5. This means that
suitable locations for constructing underground dams with the fuzzy range of 0.5 to 1 found in
less than 2% of the Sarakhs basin.
Conclusion The superiority of fuzzy method for more scalability from other overlaying
methods comes from this fact that in the second step of site selection and in the different
management scenarios, we can take advantage from multiple fuzzy ranges.
