Coastal Processes


A comprehensive coastal process investigation has been completed for Humber Gateway Offshore Wind FArm. Hydrodynamic (tidal) wave, sedimentological and morphological regimes have been investigated, using information from a variety of sources. It is shown that the tidal regime is the dominant process with regard to sediment mobility across the wind farm site, with the waves becoming more dominant in the shallower waters. Of note is that the sea bed sediment is generally coarse and as such there is limited potential for mobility under tides. The most extreme waves originate from the 330oN to 030oN directions, with the typical significant wave height being in the range 0.25m to 0.50m in the wind farm site. Sea bed conditions across the area proposed for development appear to be relatively stable, with only isolated morphodynamic features present. To the south of teh development site, New Sand Hole and Silver Pit are noteworthy bathymetric features, providing a natural boundary between the Humber Gateway and those proposed for development to the south, also within the Greater Wash SEA. Sediment transport is typically in a southerly direction, with littoral transport along the adjacent coastline providing a pathway for material reaching the HUmber Estuary, the Lincolnshire shore and The Wash.
