ESTUARY GEOMETRY AS A FUNCTION OF TIDAL RANGE

Brian O'Connor, John Nicholson, Ralph Rayner

Abstract


The tidal characteristics, and consequently the morphology, of an estuary can be altered substantially by engineering works. A method is suggested for estimating the magnitude and the time-scale of the resulting morphological changes. This method is then applied to the Welsh River Usk which will be affected by the construction of a planned tidal power barrage across the nearby Severn Estuary.
