Abstract:
Geospatial technology has wide applications in the groundwater resource assessment studies.
Satellite images are increasingly being used in groundwater exploration due to their utility in
distinguishing numerous geo-system options. The present study has been disbursed in and
around Gondar, Ethiopia. The groundwater potential zones were depicted from the six geosystem parameters like lithology, lineament density, geomorphology, slope, land use/land
cover, and drainage density using weighted overlay analysis methodology. Integration of the
above mentioned geo-systems has been performed in GIS platform using weighted overlay
analysis. Totally different categories of thematic maps were analyzed and assigned rank and
weights based on groundwater occurrences, and eventually, the above said thematic layers
were integrated in the GIS platform. The ultimate map indicates the groundwater potentiality
within the study area, which was classified into three categories: high, moderate and low. A
total of 24% of the study area falls in low groundwater potential zone, 42% in moderate
potential zones and 34% of the realm in the high potential zone.
