EFFICIENTLY FORECASTING 2-DIMENSIONAL SPECTRA INSIDE SHELTERED PORTS USING SPECTRAL AND PHASE-RESOLVING WAVE MODELS

Abstract

Ports today are grappling with the impacts of increasing ship sizes and increasingly frequent and more extreme weather events. Under these conditions, being able to predict navigation, handling, and mooring risks accurately, is becoming more crucial to safe and efficient port operations. This is especially important in ports subject to complex wave transformations. Traditionally, in order to capture the various wave transformation processes accurately from offshore to nearshore areas, the coupling of a Spectral wave (SW) and Boussinesq wave (BW) model has been required. Unfortunately, the very high computational costs of BW modelling have inhibited running such models in forecast mode. In response to this highly technical challenge, DHI have developed a transformative method for concatenating outputs from SW and BW models, enabling modelers to forecast 2D Spectra accurately, both inside and outside a sheltered port basin in a computationally efficient manner.
