Afficher plus [+] Moins [-]This report documents a numerical modeling system named GENESIS which is designed to simulate long-term shoreline change at coastal engineering projects as produced by spatial and temporal changes in longshore sand transport. Typical longshore extents and time periods of modeled projects can be in the ranges of 1 to 100 km and 1 to 100 months, respectively, and almost arbitrary numbers and combinations of groins, detached breakwaters, seawalls, jetties, and beach fills can be represented. GENESIS contains what is believed to be a reasonable balance between present capabilities to efficiently and accurately calculate coastal sediment processes from engineering data and the limit in both the data and knowledge of sediment transport and beach change. The modeling is operated through a structured and user-friendly interface so that the operator need not become familiar with detailed aspects of the computer code. This report serves as a technical reference to Version 2 of GENESIS and is also designed to be an operator's manual by providing instructions for using the interface. The method for applying the model is described from the perspective of the needs of both engineers and planners who deal with evaluate shore- protection projects. A fully documented case study involving application of the modeling system and exercise of many of its features is provided. Sweden.
