As part of the ‘Coastal Futures – Planning and Adaptation in a Changing Climate’ event series this session will focus on regional responses, local solutions and community resilience in the face of climate change. Hear from our experts about how coastal communities can prepare for and adapt to the challenges brought on by global warming.
AAEE’s 21st Biennial National Conference will attract over 250 dedicated sustainability and educational professionals from across Australia as well as virtually from New Zealand, our overseas neighbours and MOU Partners in the United States, Japan, and Abu Dhabi.
Inspired by moving local examples, resilience theory, future’s thinking and Mandurah’s relaxed waterside lifestyle, Mandjoogoordap: Changing Tides aims to showcase examples of people coming together to create positive change through environmental education, along with innovative, practical and effective tools for change-making.
It’s the place where sustainability and educational professionals can connect and learn, by bringing together academia, industry and leading professionals.
Please join The University of Western Australia's Ocean Institute, Public Policy Institute and Wave Energy Research Centre for your say on how we prepare and adapt to our changing world.

Several organisations worldwide are engaged in digitalising environmental assessment. The Danish DREAMS project presents a list of international frontrunners highlighting organisations, initiatives, partners and key takeaways. It provides a great opportunity for inspiration and learning from the global community.
WABSI continues to work with industry, regulators, researchers and the community to build a data sharing and access culture that enables us to better understand the cumulative environmental impacts, of an action, on a region, overtime. Read more about our work here.
Marine Park zonings in Western Australia include the Great Southern Reef, Ningaloo and Shark Bay. These iconic coastal environments are home to kelp forests, seagrass meadows, and tropical coral reef: vibrant and unique ecosystems that are all under threat from ocean warming.
With enormous blue carbon potential, these bio-diverse hotspots are ground zero in the war on climate change. Philanthropically supported research at UWA’s Oceans Institute into these marine ecosystems and their conservation is providing innovative solutions for protecting their habitats.
In this webinar, hosted by Oceans Institute Director, Associate Professor Julian Partridge, four leading UWA marine scientists will discuss how their work is making a difference.

Abstract
Sea level variability occurs at different time scales (hours to decades) and is crucial for a range of activities including navigation, coastal stability and coastal planning. By contrast, societal concerns on sea level variability originate from potential impacts including coastal flooding, shoreline recession, damage to coastal infrastructure and natural resources. This is particularly true along the coasts of Vietnam and the Australian North West Shelf (NWS) that are susceptible to impacts from tropical cyclones (TC) and mean sea level change. This talk examines two themes: (1) seasonal and inter-annual sea level along Vietnam coast; and, (2) storm surge dynamics along the NWS.
Along the Vietnam coast, the seasonal sea level variability in open coast is dominated by a reversal of monsoons, whist in Tonkin Bay in the north is influenced by the Red river discharge. The inter-annual sea level in the open coast is driven by ENSO (El Niño Southern Oscillation), and is attributed to inter-annual change in boundary currents. The northern section of the Vietnam coast is dominated by the 18.6 year nodal tide whilst in the south, inundation in the Vietnam Mekong Delta is controlled by the interaction between ENSO and the 4.4 year lunar perigee cycle.
Along Australian NWS, the translation speed of a TC is a critical factor that determines generating mechanism and features of storm surge components. A combination between observations and numerical simulations utilizing the Regional Ocean Modelling System (ROMS) showed that the forerunner and continental shelf waves (CSW) were likely to be generated by a slow moving TC (<6 ms-1), whereas edge waves were attributed to fast translation TC’s (>6 ms-1). Magnitude of the forerunner and edge waves were sensitive to TC translation speed, but CSW was not sensitive to the translation speed of the TC.
Observational data obtained during passage of Tropical Low (TL) 14U in 2017 together with ROMS were used to investigate the generation of CSW and its interaction with topographic features that include Barrow and Montebello Islands. The TL 14U’s forward speed was close to a phase speed of the CSW resulting in an amplified CSW due to resonance. When the 14U and the CSW interacted with Barrow Island, the sea level increased by up to 40cm due to the blocking effect of the shallow water resulted in strong currents (~1.2 ms-1) flow diverted around Montebello Island due to blocking effects of topography.
