Numerical models of sediment transport phenomena in shallow water are very useful to understand the erosion mechanisms in real cases. The Authors present a typical Italian pocket beach affected by an evident erosion trend. The paper aim is to understand the natural behaviour of this peculiar pocket beach and consequently determine the causes producing the net sediment loss. The work is conducted applying a new integrated Coastal Area Model by mean the nearshore circulation and sediment transport dynamically linked to predict morphological and 3D bathymetry changes. The paper shows results from two different scenarios: the extreme sea storm event occurred in 28-29 December 1999 and a morphological average wave condition.

Abstract
Numerical models of sediment transport phenomena in shallow water are very useful to understand the erosion mechanisms in real cases. The Authors present a typical Italian pocket beach affected by an evident erosion trend. The paper aim is to understand the natural behaviour of this peculiar pocket beach and consequently determine the causes producing the net sediment loss. The work is conducted applying a new integrated Coastal Area Model by mean the nearshore circulation and sediment transport dynamically linked to predict morphological and 3D bathymetry changes. The paper shows results from two different scenarios: the extreme sea storm event occurred in 28-29 December 1999 and a morphological average wave condition.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
