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 . | VNU Journal of Science Earth Sciences 23 2007 244-252 Studying shoreline change by using LITPACK mathematical model case study in Cat Hai Island Hai Phong City Vietnam Nguyen Ngoc Thach1 Nguyen Ngoc Truc1 Luong Phuong Hau2 1 College of Science VNU 2 Hanoi University of Civil Engineering Received 05 April 2007 received in revised form 10 September 2007 Abstract. 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. Keywords LITPACK model Hydrodynamic-lithologic Simulating Along time Shoreline change. 1. Introduction of LITPACK Numerical Model .
