Cycling of Elements in Estuaries

Meaningful evaluation of the ecological stresses imposed by man's release of heavy metals or radioisotopes into estuaries requires an improved understanding of the interactions between the waste materials and the functional components of the ecosystem. In this paper, we review and discuss the types of information required for the development of useful models for the cycling of contaminant metal...

Flow dynamics over hollows in estuaries

Observations of flow over hollows (bathymetric depressions) at various estuarine systems suggest that their speed increases locally at the deepest part. Numerical experiments were carried out to investigate the reason for this acceleration. Results show that the flow is convergent before and then divergent after it passes over the hollow. However, the simulated current speeds in the hollow decr...
