Delineation of groundwater potential zones (GWPZ) has been performed for a
coastal groundwater basin of eastern India. The groundwater potential zone index (GWPZI)
map is generated by using Analytic Hierarchy Process (AHP) from different influencing
features, e.g., Land Use/Land Cover (LU/LC), soil (S), geomorphology (GM), hydrogeology (HG), surface geology (SG), recharge rate (RR), drainage density (DD), rainfall (RF), slope
(Sl), surface water bodies (SW), lineament density (LD), and Normalized Difference
Vegetative Index (NDVI). Recharge rate values are estimated from hydrological water balance
model. Overlay weighted sum method is used to integrate all thematic feature maps to generate
GWPZ map of the study area. Four zones have been identified for the coastal groundwater
basin [very good: 36.39 % (273.53 km2, good: 43.57 % (327.47 km2), moderate: 18.27 %
(137.30 km2), and poor: 1.77 % (13.27 km2)]. Areas in north to south-west and south-east
direction show very good GWPZ due to the presence of low drainage density. GWPZ map and
well yield values show good agreement. Sensitivity analysis reveals that exclusion/absence of
rainfall and lineament density increases the poor groundwater potential zones. Omission of
hydrogeology, soils, surface geology, and NDVI show maximum increase in good GWPZ.
Obtained GWPZ map can be utilized effectively for planning of sustainable agriculture. This
analysis demonstrates the potential applicability of the methodology for a general coastal
groundwater basin
