Abstract
The hazards associated with construction on sabkha soils may include strength reduction, soil subsidence as a consequence of the dissolution of salts, corrosive action caused by the salinity of the soil and groundwater, heave during salt recrystallization, flooding due to the low rate of infiltration into sabkha soils and groundwater rise in urbanized areas. As a consequence, extensive sabkha areas along both the Red Sea and the Arabian Gulf coasts have been left undeveloped. Some of the sabkha areas that have been built on are now suffering from one or more of these hazards. Nevertheless, sabkha terrain may be a useful resource for minerals and fresh water. The paper reports a trial to investigate the possible industrial utilization of the sabkha resources at Al-Lith on the Red Sea coast. The results indicate that by using a solar still the sabkha can provide a renewable source of fresh water, Na, K and Mg.
