Abstract :
Coastal erosion significantly threatens sandy
beaches worldwide, impacting coastal communities and
ecosystems. This research investigates the application of
SBEACH (Storm-induced BEAch Change), a numerical
beach modelling computer programme, as a tool for
coastal engineers to predict beach profile evolution in
response to wave and tidal actions. The study used
SBEACH simulations to explore the equilibrium beach
profiles under varying conditions, including wave height,
wave period, sediment grain size, and beach slope.
This study also examined the effects of storm tides
on equilibrium profiles and proposed protective sand
dunes' dimensions to safeguard against storm surges.
This research highlights SBEACH's potential as a
valuable tool for assessing and planning coastal erosion
mitigation strategies. While SBEACH provides insights
into cross-shore beach profile dynamics, combining it
with GENESIS offers a more comprehensive approach
to coastal management. However, it is crucial to consider
real-world engineering experience and safety factors
when deciding on beach stabilisation and protection
measures. Coastal countries can benefit from such
modelling approaches to better manage and protect their
sandy beaches, which play a crucial role in coastal
defence and maintaining ecosystem integrity.
