Surface water/groundwater relationship in Chaj Doab

In order to understand the relationship between surface water and ground water in Chaj Doab (Pakistan), isotopic and chemical studies were undertaken. The data show that north eastern part of the doab, surface water and ground water are generally well connected and the recharge is mostly from the rivers either directly or through irrigation channels. Salinization of ground water is mainly due to dissolution of salts from soil sediments. (author)
