Globally, salinity intrusion is a frequent and ubiquitous problem in any developed coastal aquifer system, which is also experienced by the regional aquifer in southwestern Bangladesh. Immediate attention must be paid to quantify the extent of this problem for taking the appropriate countermeasures. Nowadays, numerical modeling technique plays an important role in this regard since traditional analytical approaches are insufficient to replicate the physical system adequately. This book demonstrates a new system of numerical modeling for an integrated river-aquifer system by taking the...
