Results

The hydrological model produces annual forecasts of chloride concentration in groundwater in the short term and long term. The results for each case study area are presented in Fig. 7.4 for Coastal 1 area and Fig. 7.5 for Coastal 2 area, for each of the scenarios described in Table 7.6. The figures show that the salinity level is lower in scenarios with greater restrictions.

The results are shown for scenarios 1-8, with the following characteristics described next to each scenario: Town freshwater/ Wastewater salinity/ Pumped water priority: T = Town, A=Agriculture.
