Storm tide amplification and habitat changes due to urbanization of a lagoonal estuary [PDF]

Natural Hazards and Earth System Sciences, 2020
In recent centuries, human activities have greatly modified the geomorphology of coastal regions. However, studies of historical and possible future changes in coastal flood extremes typically ignore the influence of geomorphic change.
