Abstract: | At a time when we discover the virtues of the environment, protection of water
resources and more specifically the underground appears to be a major objective that
managers must incorporate the territory in local policy management and planning.
The characterization of the intrinsic vulnerability of groundwater is an excellent
tool; more and more developed and experienced by researchers in hydrogeology. We
conducted a study on the alluvial aquifer of Sebaou which provided a tool to help
managers of water resources and land use in their decision making. To do this, we used
two approaches, the first is the DRASTIC method, the second, DRASTIC improvement,
it is to characterize the vulnerability / sensitivity.
Both methods were applied to the alluvial aquifer of Sebaou in Algeria, which
covers an area of approximately 1432 km2, flowing through alluvial deposits of
Quaternary age . This water plays a role in the socio-economic development of the
region, whether the supply with drinking water, agricultural or industrial. The water of
high Sebaou driven mainly by surface water and the main tributaries therefore subject to
all types of pollution.
The comparison of maps obtained by the two methods shows that the first
highlights three hydrogeologic units at medium, high and very high vulnerability, while
the second tends to overestimate the vulnerability since we got only one map with only
one hydrogeologic unit with very high vulnerability.
