Coherence between coastal and river flooding along the California coast
Kingsley O. Odigie, Jonathan A. Warrick
2018, Journal of Coastal Research (34) 308-317
Water levels around river mouths are intrinsically determined by sea level and river discharge. If storm-associated coastal water-level anomalies coincide with extreme river discharge, landscapes near river mouths will be flooded by the hydrodynamic interactions of these two water masses. Unfortunately, the temporal relationships between ocean and river water masses...
