Gold Coast Estuarine  Wetland Mapping Project (2012 -2014 [SWEMP 2]

Gold Coast City Councilrl_187-200

Contact: Grant Periott

0414180449

We used Council’s tidal , storm surge  and flood hydraulic models and our watercourse and flood risk modelling too to map the location of intertidal wetlands, estuary channels, estuary wetlands, saltmarshes, floodplain wetlands.  We al so were able to assess the potential impacts of sea level rise on these ecosystems. This assessment can also be used to determine risk of flooding, tidal and storm surge  inundation in adjacent urban areas.

We undertook a major process study of the Coomera River Estuary. Assessments included hydrographic and hydraulic assessment, riparian vegetation assessment, tidal dynamics and tidal exchange, geomorphic stability, geotechnical, acid sulphate soil assessment. We calculated annual sediment transport rates through the estuary  from bathymetry surveys and identified erosion and deposition zones from detailed two dimensional hydraulic analysis of flood events.  We undertook a geotechnical and morhostratigraphic assessment of foreshore sediments and located acid sulfate soils with respect to the geomorphic evolution of the estuary. We mapped riparian and intertidal vegetation for the whole estuary. We prepared a foreshore management plan for the estuary. We assessed foreshore stability and examined the potential for foreshore erosion. We prepared detailed foreshore restoration designs for five council managed parklands.

Gold Coast Watercourse, and Wetland Mapping Project (2012 – 2014) [SWEMP 1]

Gold Coast City Council2pw watercourse modelling

Contact: Tony Adkins

(07) 55811520

We developed a watercourse and flood risk modelling tool that was used to map the location and area (polygon) of a watercourse and flood prone area to +/- 5m for any river catchment in the world. The tool has also been used to identify fluvial geomorphic units on the floodplain including; multiple channels, anabranches, oxbows, intertidal areas, floodplain wetlands, chute channel, etc. The watercourse modelling tool has been used to model the location of watercourses, and wetlands for the City of Gold Coast, covering an area of approximately 1200 km2  This assessment can also be used to determine risk of flooding and also determine appropriate setbacks for development.

Contact: Mars Oram

(07) 5581 6386

Undertook a detailed floristic, geomorphic, hydraulic and ecological assessment of the Lower Coomera River. Assessments included hydrographic aassessment of stream gauging data and used statistical analysis to determine significant flood events that caused significant channel change and flow duration curves were used to determine low flow characteristics used to determine required environmental flows. Geomorphic stability and geotechnical assessments were undertaken in association with two dimensional hydraulic modelling to determine erosion hot spots, likely breaches to the bund wall and predict channel changes in the river. Mapped riparian and estuary vegetation for the whole estuary. Prepared a river management and restoration plan, including detailed design for bed and bank stabilisation, and bundwall stabilisation. Designed a high flow bypass between the river and the excavated quarries so as to avoid bund wall breaches in the future and repair an existing bund wall breach.
