The occurrence of salts in water, the principle of salt balance, and the effects of salts on plants are examined. It is suggested that water becomes essentially valueless for irrigation when its electrical conductivity approaches 7.5 millimhos per cm, and the term degradation ratio is proposed to express the equivalence of a saline water to good quality water. Degradation of water quality in a river system with progress downstream may be inevitable, but the bypass, regulatory, watershed management, and conveyance and distribution techniques to control this degradation are explored.
