WebSalinity is important in particular as it affects dissolved oxygen solubility 3. The higher the salinity level, the lower the dissolved oxygen concentration. Oxygen is about 20% less soluble in seawater than in freshwater at the same temperature 3. WebDryland salinity is closely linked to other soil degradation issues, including soil erosion. Salinity is often associated with prolonged wetness and lack of surface cover and therefore increases the vulnerability of soils to erosion. Flood risk Shallow water tables can increase the risk of flooding.
