Numerical simulation of saline water intrusion in the Karnafuli river

Abstract

A one-dimenstional numerical model for the simulation of salinity intrusion in the Karnafuli river system, consisting of three branches connected at the junction, has been developed the model was calibrated and validated by simulating salinity intrusion lengths under two widely different hydraulic conditions. The model calibration was also checked by comparing highs and low-water slack salinity data along the lower reach of the river Assumption made it formulating sea-face boundary condition has been validated.
