Title: High resolution coastal modelling prospects for South Africa


Abstract: South Africa is in the privileged position to be situated between the Atlantic and Indian Oceans. Part of the Exclusive Economic Zone (EEZ) of South Africa are vast areas in the Southern Ocean surrounding the Gough and Marion islands. The South African Weather Service (SAWS), together with other parastatal institutions, has various mandates when it comes to research, governance and management of our oceans. SAWS has recently embarked on a quest to provide high resolution coastal ocean forecasts for the southern and South African coastline. This quest is an element of the aptly named the Marine Master Plan, and consists of various phases of research and forecasting tool development. Most of the development is planned in-house, but with close collaboration with national and international partners. This talk will provide the audience with an overview of planned developments and research endeavours. The tool developments include an operational tool for storm surge forecasting, high resolution fully spectral wave model outputs for southern Africa, a wave energy exposure atlas and high resolution circulation modelling for key focus areas. Amongst others, applications of these models will include sewage plume behaviour research and eventual forecast (associated with desalination plant construction sites), assistance in search and rescue operations and eventually regional scale offshore to nearshore ship routing tools. Research topics include the calibration of the models to be developed and investigation of physical phenomena unique to the southern African coastline. Multi, inter and transdisciplinary research is also being conducted and an overview of these project will be discussed.
