Abstract

Initial delineation of prospecting zones of groundwater was conducted in the present study
using remote sensing and geographic information system (GIS) techniques. It has been preparing
an integrated geographic database of spatial and non-spatial data for the study area. The spatial
data were generated by using image processing software (Erdas 8.3) and GIS software (Arc view
3.3) enhanced by real frequent field visits of the study area. These data include: surface features
which give a direct and indirect indicators of the existence of groundwater and affect to the
groundwater movement such as hydrogeomorphological, drainage density, slope, landuse and
soil maps. The non spatial data were derived primarily from real views during field visits to the
study area and from the existing writing or previous studies. All the data generated were saved in
the GIS databank for the purpose of digitization, computational and generate the best possible
output results to determine the extent of possible areas where the water that exists for the purpose
of prospecting. Results showed that more areas could be have very good categories of prospect
zones are the southern parts of the study area, which covers about 375 Km2 while the northern
areas, which covers about 164 Km2 of the study area are grouped as runoff zone. Accordingly the
possibilities of the presence of groundwater are poor to negligible in this zone. The current study
demonstrated that a remote sensing and GIS technique are very effective tools that can give the
initial predictions on the presence or probability of the presence of ground water in areas which
have the same considered geological deposits for the study area.
