Shaping and evaluation of physical parameters for Farwa Lagoon - Libya

Farwa complex suffers the effect of pollution, temperature change and the high evaporation process. These effects include but are not limited to physical changes like water properties and the island's shape over time, as results of wave motion and direction. The only study that related to this issue was reported by (M. GERGES & A. DURGHAM, 1982) as part of the UNESCO mission. Their study concluded the results of high salinities, approaching 42 % in winter, 43 % in spring, and 44.5. %. in summer, and 43 %. in autumn, are most probably obtained through the evaporation process. Here we expressed our work by InSite examination and satellite image to evaluate these physical parameters. Results reported that TDS dropped from 11203 ppm at 27.7 C to 10430 ppm at 29.2 C and the daily average DO was between 3.0 mg/L and 3.7 mg/L. in addition, the value as inflow needs to be increased by extending the bath or the waterway at least 40 m wide and 3 m deep to let more water come thru it. This engineering proposal will raise the water level inside the lagoon as well as, expend the aquatic life in the area.
