The webinar will present the latest status and future plans for the NSW Nearshore Wave Program including the recently released update to the NSW Nearshore Wave Transformation Toolbox. The presenters will cover the motivation behind the program and describe the toolbox development, technical background and use cases. Wave observations in shallow coastal waters are essential for creating wave models to predict sediment transport, shoreline change, and coastal hazards, yet despite there being a good coverage of in-situ measurements for deeper ocean waters, data remains sparse for shallower waters (<35 m).
This presentation will introduce the audience to a growing dataset and methodology of in-situ wave buoy observations from shallow coastal waters in New South Wales that comprises over 7,000 days of measurements at over 20 locations. This data has been used to develop an updated nearshore wave tool, which provides accurate, high-resolution wave data along the entire nearshore (< 30m depth) of the NSW coast.
The Toolbox provides users the ability to transfer either historical offshore Waverider buoy data or deep-water modelled hindcast data to a nearshore location of interest. The user can display nearshore wave conditions in spatial maps, timeseries plots, directional spectra plots, and download time series for offline use. Additional features of the revised toolbox will enable the user to run an Extreme Value Analysis (historic coastal storm feature) on the transformed nearshore wave conditions; to inform coastal planning and management of NSW.
Sean is Coastal Engineer with 20 years experience and has provided professional services and project management of major coastal process, hazard and management studies. Over this time he has developed a detailed understanding of the coastal zone. He has specialist experience in the fields of coastal, ocean and offshore engineering, numerical modelling, statistical modelling and data analysis.
Tom is a coastal scientist managing and co-leading the state-wide coastal science program, which aims to collect high resolution coastal data to underpin coastal management in NSW. Tom has a background in coastal geomorphology and likes to use a diverse set of technologies to collect coastal data, some of these include drones, underwater echosounders, and laser sensors alongside ground truthing methods, to map the bathymetry, geomorphology and ecological aspects of the NSW coastal environment. Tom’s professional experience spans university, private and local government sectors.
