This study was conducted in Karamenderes Basin (KMB), Canakkale-NW Turkey. Possible storage areas of groundwater in the basin were prioritized by using morphometric data, digital elevation model (DEM), topographic maps, geological maps, satellite image, and geographic information systems (GIS). Six sub-basins were identified as a result of the interpretation of all the cartographic materials. After the calculations which made for the all sub-basins it was determined that which sub-basins have the highest potential to storage the groundwater. Sub-basins compared with each other. According to these data, (SubW-3) and (SubW-2) having geological impermeable lithology and more hard rocks, low bifurcation ration (Br), high drainage density (Dd) and stream frequency (Fs) were identified to have the lowest repository potential for groundwater. On the contrary, (SubW-4) and (SubW-1), which have higher drainage density (Dd) and stream frequency (Fs) and lower bifurcation ratio (Br), generally formed on quaternary alluvium, clastic limestone and marl, have a higher potential for storing groundwater. CORINE land cover map showed that areas which have higher groundwater storage potential under agricultural usages.
