| ABSTRACT: | The report estimates the components of the balance of chlorides in the coastal aquifer of Israel and assesses the trends of salinization in the future. The sources of chloride which have been identified and estimated include: rainfall, dry fallout, leakage from adjacent aquifers, sea water intrusion, artificial recharge, import of water from Lake Kinneret and the mountain aquifer for direct supply, percolation of surface water, and the addition of chlorides to the sewage which percolates into the aquifer. The computations are based on a subdivision of the aquifer into strips perpendicular to the coastline with a further subdivision of a strip into cells. A multicell model of a strip was used to simulate advection of chloride as an inert solute under unidirectional steady flow conditions in the saturated zone. The transport of chloride through the unsaturated zone is vertical by advection only. It is characterized by the travel time from the surface of the ground to the groundwater table. A computer code based on this model was used to reconstruct the map of chloride concentration in the 30’s, to reconstruct the rate of increase in the decade 1965-1975, and to obtain an assessment of the concentration trend in the future. The special data file of chloride concentrations in pumping wells, which was prepared for the project, contained data from 1800 wells for the period 1950 - 1971. Apart from the predicted changes in the concentration of chloride in the pumped water and in the aquifer, the report also reviews possible ways of suppressing the rate of salinization. |
