The Effect of Runoff on Saltwater Intrusion in Weak Tide Estuary

The Effect of Runoff on Saltwater Intrusion in Weak Tide Estuary

Modaomen Estuary is a typical weak tidal estuary. The saltwater movement distance is not monotonic relationship with the tidal dynamics, it is also related to the strength of the salt wedge. In different phase of saltwater intrusion, saltwater intrusion distance has different responses to runoff. Th...
