• the key influencing factors of cyclones and other severe weather events and theirinteraction in relation to the assimilation and transport of pollutants entering marinewaters from, or adjacent to, the project area.Describe the environmental values of the coastal resources of the affected area interms of the physical integrity and morphology of landforms created or modified bycoastal processes.Describe the tidal hydrodynamics of the project area and the adjoining tidal waterwaysin terms of water levels and current velocities and directions at different tidal states.Undertake two- and three-dimensional modelling. Provide details of water levels andflows associated with historical and predicted storm surges.Describe the wave climate in the vicinity of the project area and the adjacent beachesincluding inter-annual variability and details of historical and predicted extreme waveconditions generated by tropical cyclones or other severe storm events.Describe the hydrology of the area and the adjacent catchments of the rivers and theassociated freshwater flows within the study area and the adjoining tidal waterways interms of water levels and discharges. Detail the interaction of freshwater flows withdifferent tidal states, including storm tides. Describe inter-annual variability and detailsof historical and predicted floods including extent, levels and frequency. Flood studiesshould include a range of annual exceedence probabilities for affected waterways,where data permits.Predict the likely changes to hydrodynamics (including water levels, currents, waveconditions and freshwater flows) and sedimentation in the project area due to climatechange.Potential impacts and mitigation measuresDescribe the potential changes to the hydrodynamic processes and local sedimentationresulting from the construction and operation of the project, including dredging anddredge spoil disposal. This should include:• impacts on tidal flows and water levels• changes to sediment transport patterns.This assessment should also discuss the potential impacts associated with extremeevents such as storm tide flooding (see also Part B, Section 8.3 of this TOR). This mustinclude an assessment of the vulnerability of the project to storm tide flooding and thepotential of the project to affect vulnerability to storm tide flooding on adjacentproperties.When assessing the hydrodynamics of the area and movement of sediment along thecoast, consider coastal processes such as erosion and accretion at adjacent locations.5.3.2. Coastal water qualityDescription of environmental valuesProvide baseline information on water quality of coastal waters and areas potentiallyaffected by sediment run-off or dredging. This information should include (but is not- 32 - Contents of the EISDudgeon Point Coal Terminals ProjectTerms of reference for an environmental impact statement
