Wave Model Study of a new Marina Development in Victoria Harbour, BC, Canada. Numerical modeling is a powerful method of visualizing the dynamic behavior of physical systems. With only a sparse data set, predictions can be made of currents, water quality and sediment transport. Modeling also allows for " what-if " studies to determine the impact of coastal engineering structures and other changes in the environment. ASL has its own model (ASL-COCIRM-SED) for current, sediment and water-quality studies. ASL uses commercially and freely available numerical models, such as the SWAN wave model, for other studies. Ice edge tracking using the ASL-COCIRM-SED model.
