Remember that excessive salinity (seawater or brackish water) can only be reduced by using the reverse osmosis or electro dialysis membrane techniques (see chapter separation by membranes) or by distillation (see chapter degasification, odour control, evaporation).

The correct answer is A. The body of water located at Letter D on the map is the Gulf of Suez.

The first requisite in the prevention or elimination of waterlogging and salinity problems is an adequate drainage system. Very often the natural drainage in an area, along with good water management, is sufficient to eliminate excess water and preclude the need for expensive subsurface drainage systems.

Salinity levels are important for two reasons. First, along with temperature, they directly affect seawater density (salty water is denser than freshwater) and therefore the circulation of ocean currents from the tropics to the poles. Measuring salinity is one way to probe the water cycle in greater detail.

The main point is that excess salinity in soil water can decrease plant available water and cause plant stress. Soil water salinity is dependent on soil type, climate, water use and irrigation routines.

Hydration – Sea salt helps the body absorb water for optimal hydration, as well as helps the body stay hydrated for longer periods of time.

Saltwater itself is not bad for your skin, but constant exposure to a combination of salt, sun and sand can irritate and dry out skin, especially for those with a history of dry skin or other issues like eczema.

Experts say that your skin can literally fall off if you spend prolonged periods of time in the tub, day after day. “”In essence, prolonged immersion in water supersaturates the skin and can lead to skin breakdown,” Dr. Fromowitz said.

Generally, a person can survive in 41-degree F (5-degree C) water for 10, 15 or 20 minutes before the muscles get weak, you lose coordination and strength, which happens because the blood moves away from the extremities and toward the center, or core, of the body.

But new research suggests a long, hot bath may be as helpful to you as a gentle workout session, too. British researchers report that hot-water immersion — that is, a long sit in a hot-water bath — may help reduce inflammation and control blood sugar levels in much the same way exercise does.
