Coastal aquifer management requires rapid and effective decision making as regards rapid ground water salinity and volume changes. This can be assessed only by means of an efficient sea water monitoring network that can lead to a more exact location of sea water intrusion and the ground water quality trends of the area of study and a hydrogeologist who understands the mechanism of the aquifer. This article proposes a “heuristic” approach for prioritizing aquifer areas for improving the monitoring network by adding new observation wells and renovating old ones. Such an approach improves aquifer control by recommending where additional and renovation observation wells are required regarding sea water intrusion along coastal aquifers. The data in use for this approach consist of variables characterizing the hydrological situation in the aquifer and the technical conditions of sea water intrusion network observation wells within their ground water salinity environment. Applied to Israel’s coastal aquifer, this approach leads to a list of areas with highest priorities, most of which are located in the northern portion of the Coastal Plain aquifer. Such a list is a basis document for decision making, which helps focus upon areas where it is most urgent to improve the quality of information by drilling new observation wells or by rehabilitation of the technical conditions of the present sea water intrusion observation well network. Considering the results obtained, this approach may be considered as a means for requiring further input data for various hydrological models and for operational activities in the field.
