Nowadays, there are many methods to study shoreline change in coastal engineering.
Among them, mathematical methods are considered as effective ones that have been used for a
long time. LITPACK is a numerical model in MIKE software package, developed by Danish
Hydraulic Institute (DHI), for simulating non‐cohesive sediment transport in wave and currents,
littoral drift, coastline evolution and profile development along quasi‐uniform beaches. In this
paper, the authors apply the model for studying shoreline change in Cat Hai Island, Hai Phong
City. Cat Hai is a famous island with dense population working with various coastal ‐ tradition
works locating at the centre of Hai Phong, where coastal line is changing with high speed and
complicated cycles. Based on the analysis of hydrodynamic‐lithologic conditions in this area, a
coast protected structure system has been proposed, consisting of revetments, groynes, submerged
breakwaters and emerged breakwaters. Results derived from LITPACK model show that they are
reliable enough and suitable for use as remedial protecting measures. |
