  title={Estuary Geometry as a Function of Tidal Range}, 
  abstractNote={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 timescale 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.},
