WebSalinity is the measure of the amount of dissolved salts in water. It is usually expressed in parts per thousand (ppt) or percentage (%). Freshwater from rivers has a salinity value of 0.5ppt or less. Within the estuary, salinity levels are referred to as oligohaline (0.5-5.0 ppt), mesohaline (5.0-18.0 ppt), or polyhaline (18.0-30.0 ppt).
WebIn contrast, irrigation water with higher salinity than the soil tends to cause particles to stay together, maintaining soil structure.

Its extremely low elevation means that water cannot escape the Dead Sea once it enters, and exposed to the intense heat, the water evaporates more quickly, leading to an intense salinity. Why do you float in the Dead Sea?
Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰).
