Eco-Hydrodynamic Simulation of the Dreissena Polymorpha (Zebra Mussel) in Fluvial Ecosystems. Application to the Study of the effects of Climate Change on Zebra Mussel Growth in Mequinenza Reservoir

摘要

Computational models integrating the biological and physico-chemical dynamic of fluvial ecosystems with the hydrodynamics of the waterway are an essential tool for the study of the ecology of significant species and for protecting and restoring river health. This includes the prevention and control of invasive species. In this context, a 2D eco-hydrodynamic model has been developed, synthesising and adapting previous biological and physical models, the results of which describe concentrations of phytoplankton, chlorophyll, zooplankton, detritus, organic and inorganic nutrients, oxygen, benthic vegetation and the growth of zebra mussels of all size classes over time. Zebra mussel population growth is simulated according to a size-structured model. The growth of one mussel is computed according to the bioenergetic model, temperature function, mussel size and concentration of phytoplankton.
