Derwent Coastal Catchment Initiative: Hydrodynamics and Sediments

Details
Aims: 

The Derwent Estuary Program (DEP) identified the need for predictive capacity to augment a decision support system for the Derwent Estuary. This management system is designed to aid effective decision making regarding environmental issues, and predictive models play an integral role in assessing management scenarios and achieving system understanding. Of particular importance is the issue of heavy metal pollution, and coupled hydrodynamic, sediment and heavy metal prognostic models are important tools that may assist the formulation of management strategies. The goal of the hydrodynamic component of the DEP is to provide a hydrodynamic model that may assist in management strategy evaluation within a management framework.

Time Scale: 

Time ranges of flushing times (days).
Seasonal effects of flushing.
Forecasting models and scenarios.

Outputs: 

The study provides a hydrodynamic model that may assist in management strategy evaluation within a management framework, and provide understanding into the physical dynamics of the estuary (water transports, mixing regimes and temperature / salinity distributions) and the relationship between process occurring on different time and space scales. The hydrodynamic model forms a base into which sediment, contaminant or biogeochemical models may be coupled.
