GUI 시스템을 개발하여 여러 모듈을 통합하였다. GUI시스템에 흐름장， 퇴적물 이동관련 입력부 뿐 아니라 파랑에 의한 기인력을 산출할 수 있도록 SWAN， IWPH의 입력부를 GUI 시스템 내에 구성하였다.

IV. Research results
Research results for each year are as follows :
Individual modules related to water depth tide creation from digital hydro-chart, generation of variable-sized grids and orthogonal curvilinear grids, wave transformation, wave-induced forece, wave-induced current and tidal current, sediment transport, bathymetric change were developed in the early 4 years, and all modules were integrated in the early 5^th year. The new system was named, "Coastal Sediment Transport in Three Dimensions (CST3D)".
Development of the new program system included verification and field surveys, e.g. wave, wave-induced current, tidal current, andbathymetry around Sokcho and Mokpo areas by using drogues and ADCPs. The total system also operates with the newly developed GUI which includes SWAN, and IWPH wave modules as well as the flow and sediment transport module.
The new CST3D system based on EFDC has some distinct attributes.
1) Two wave modules
Two different types of wave modules were added.
- Existing wave model, SWAN (solving wave spectrum)
- new inter-wave-period hyperbolic type model, CST3D-IWPH(solving water level and flux, good for reflection and diffraction)
2) Flow module
- accurate pressure field (including * dynamic pressure field) is solved
- new advection scheme, Piecewise Exact Solution Method(PESM) is available
3) Sediment transport and morphological change module
- Shoreline advance and retreat are activated (Yoo, 2013).
- Prediction of bed form sizes is added (Kim et al, 2012).
- A set of empirical parameters related to non-cohesive sediment transport around Mokpo Bay.
- Bathymetric change is limited to a confined time zone.
