Demarcation of Groundwater Quantum and Quality of Lower Indus Basin: A Case Study of Seri and Muhammad Khan Distributaries

This paper presents an assessment of groundwater quality and quantum in the command areas two secondary canals lower Sindh, southern province Pakistan. These off-take from Rohri main canal Sukkur barrage Indus basin system. The scarcity water is due to climate change, population growth increased demands. farming community uses meet needs improve their livelihood. fresh Sindh only 22 percent, which available shallow aquifers underlain by salty marine nature. was assessed using electrical resistivity survey (ERS), portrayed zones through 1D inversion software (IX1D) geospatial tool inverse distance weighted (IDW). Four classes (fresh, marginal fresh, saline, highly saline) have been delineated at different depths 25 150 m below ground surface. are identified, estimated. ERS results were also compared with collected samples various depths. identified up 40 depth. could be utilized increase crop productivity conjunctive use water.
