Delineation of groundwater potential zones using GIS and AHP techniques in Coimbatore district, South India

Mapping Groundwater Potential Zones for Sustainable Agricultural Development in Entre Ríos, Ecuador

“…Regarding weightings assignment, lithology and resistivity had the most significant weights, as they were considered the most determining criteria for groundwater occurrence in the area. Compared to those above, criteria such as slope, texture and drainage density did not receive such high weights as in similar studies [15,17]. The calculated consistency ratio of less than 0.1 validated these considerations.…”

“…The AHP in this research used the most common construction parameters of GWPZ models, such as lithology, texture, slope and drainage density, according to the literature [15,17,19]. However, resistivity was also adopted as an intrinsic criterion since it strongly indicates groundwater presence [44].…”

“…Multi-criteria analysis that includes the analytical hierarchical process (AHP) allows the preparation of maps with Groundwater Potential Zones (GWPZ) from data collected or estimated as geological and geophysical information [15][16][17][18][19].…”

Delineation of Groundwater Potential Zones (GWPZs) in a Semi-Arid Basin through Remote Sensing, GIS, and AHP Approaches

“…In this area, the slope positively correlated with runoff, indicating high runoff and fewer infiltration rates [53]. Due to the aforementioned, steeper slopes are unsuitable for groundwater occurrence and are classified with very low-low groundwater potential (Table 5) [2,115].…”
