Brief description

This sub-project 'Transport Processes' - Project 3.3 aims to build on ‘conventional’ knowledge and formulations of sediment transport over open (bare) sandy beds, to develop new transport formulations applicable to a broad range of bottom types. The objectives of sub-project 3.3 (Field) are therefore to; 1) Develop new fundamental empirical relationships of sediment deposition and erosion rates applicable to a range of habitat types (e.g. coral reefs, seagrasses, etc.) as function of local hydrodynamics (waves and currents), physical properties of the sediment and bottom roughness/canopy characteristics. 2) Provide direct field measures of sediment fluxes, settlement and resuspension rates (both natural and dredge-generated) under real hydrodynamic forcing (3-week field study from 27 July–14 August 2013). 3) Incorporate new sediment transport routines applicable to a range of habitat types (developed in (1) and (2), within a community (open source) hydrodynamic and sediment transport model such as Delft3D or ROMS. In the future this new module could then easily be incorporated into any existing model. This metadata focussed specifically on the field experiments which occurred at Thevenard Island, central Pilbara and Northern Ningaloo Reef

Lineage

Statement: A three-week field study (27 July–14 August 2013) was conducted in approximately 1.5 m water depth on the reef flat at Ningaloo Reef, Western Australia, to quantify the cross-reef hydrodynamics and suspended sediment dynamics over the large bottom roughness (~20–40 cm) at the site.
Statement: Although work in remote parts of the central Pilbara was envisaged in the original sub-project plan, a unique opportunity arose to piggyback on shiptime provided by AIMS to UWA to support research activities in the region at no cost. As part of this, we were able to deploy a number of hydrodynamic instruments measuring currents and waves on the reefs at Thevenard, offshore of Onslow, for an ~5 month period (Dec 2013-Apr 2014). These represent some of the first detailed observations available of the hydrodynamic conditions over shallow reef systems in the Pilbara. In addition, through the acoustic sensors deployed, this will also provide some indication of suspended sediment concentration impacting this reef system. By hopefully combining with in situ hydrodynamic and suspended sediment concentration data from moorings deployed at the same time for the Wheatstone project surrounding Thevenard, this will provide an opportunity at minimal cost to investigate the drivers of natural sediment variability on reefs in the region, as well as potentially dredging operations occurring during the same period in this Onslow region.
