Exposure of Coastal Zones to Wind-Induced Waves
The objective is to classify coastal zones based on the WINd-Induced WAVe Height (WINWAV) analysis method. A digital bathymetry model is combined with wind velocity and direction data to compute the CERC (1984) wave height prediction model. The CERC (1984) models can be applied for a short fetch condition for locations exposed to wind blowing over an open water distance of less than 120 km, or for an undetermined fetch based wave heights prediction for wind blowing over distances of 120 km or more. WINWAV produces an image representing the absolute wave height, where each pixel forming the coastline has a numerical value that corresponds to the estimated wave height. WINWAV results also can be computed from a satellite image or digital land-water maps. In such case, WINWAV results represent a tree-class exposure scheme (e.g., low, moderate, high).
