DYRESM-CAEDYM/ELCOM-CAEDYM

Workshop

The University of Waikato

Hamilton, New Zealand

8-10 December, 2008

_________________________________________________________________________________________

Welcome to a three-day modelling workshop focusing on the models DYRESM-CAEDYM and ELCOM-CAEDYM.

CAEDYM (Computational Aquatic Ecosystem Dynamics Model) is a process-based model of the major biogeochemical processes influencing water quality. It optionally models inorganic particles, oxygen, organic and inorganic nutrients (C, N, P and Si), multiple phytoplankton and zooplankton groups, fish and bacteria. Recent developments also include optional modules for benthic organisms (e.g. clams, macroalgae), pathogens and microbial indicator organisms, and a generic geochemical module capable of simulating pH, aqueous speciation (including metals), precipitation/dissolution reactions and sediment diagenesis. (read more about CAEDYM model).

DYRESM is a one-dimensional hydrodynamics model for predicting the vertical distribution of temperature, salinity and density in lakes and reservoirs. It is assumed that the water bodies comply with the one-dimensional approximation in that the destabilising forcing variables (wind, surface cooling, and plunging inflows) do not act over prolonged periods of time. DYRESM has been used for simulation periods extending from weeks to decades. Thus the model provides a means of predicting seasonal and inter-annual variation in lakes and reservoirs, as well as sensitivity testing to long term changes in environmental factors or watershed properties (read more about DYRESM model).

ELCOM is a three-dimensional hydrodynamics model used for predicting the velocity, temperature and salinity distribution in natural water bodies subjected to external environmental forcing such as wind stress, surface heating or cooling. ELCOM is designed to facilitate modelling studies of aquatic systems over time scales extending to a few weeks, though the limit of computational feasibility depends on the size and resolution requirements of an application and computational resources. ELCOM is suited for comparative studies of the summer and winter circulation patterns, spring versus neap tidal cycles, or dispersal conditions under different flow regimes (read more about ELCOM model).
