Visualisation of Flow Dynamics in Tide-Dominated Unconfined Coastal Aquifers Using Physical Experiments

Abstract

The physical models visually demonstrate the complexity of flow processes in unstable USP as compared to stable USP situation. These experiments, for the first time, confirm the intensified mixing under unstable USP condition. The experimental results further validate the numerically established concept that land-sourced contaminants or solute plumes will have longer residence time, if an unstable USP condition persists in coastal sandy aquifers.
