Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

A depth-averaged hydrodynamical numerical model is used to evaluate tidal stresses, currents, and mixing in the Bristol Channel and Severn Estuary. Benthic macrofaunal associations and sediment bed types are shown to depend on the magnitude of the tidal stress, and the direction of sediment transport (as bed-load) in the central parts of the Channel is shown to be a consequence of ebb dominated stress. This asymmetry in the tidal stress is mainly caused by M4 currents, and computed M4 elevations and currents are compared with observed values at a number of stations. Residual flows and horizontal mixing are deduced from the hydrodynamical model, and used to construct transport relationships for an ecosystem model. Agreement between observed salinity over a number of years and that computed by the ecosystem model is generally good.
