Abstract Rainwater harvesting (RWH) structure is considered
as the best solution to conserve water for arid regions.
The selection of RWH location is based on several key determinants
such as hydrology, environment, topography, and
socio-economic. This study proposed a robust methodology
to identify and select the location of RWH using geographical
information systems (GIS) and remote sensing (RS) with
multi-criteria decision techniques in areas where data are
scarce. Several thematic maps were extracted such as vegetation
cover, soil group, slope, land use, and digital elevation
(DEM). The RWH sites were ranked based on four major
indexes: evaporation, cost-benefit, sediment, and hydrological
index. Sensitivity analysis shows that the variance inverse
(VI) and rank order method (ROM) considered all indices that
effect ranking as compared to the analytic hierarchy process
(AHP) and fuzzy-AHP. Sensitivity analysis also proved that
the proposed method is suitable to be used for RWH site
selection in arid regions.
