Abstract

This GIS dataset and supporting information providing design / extreme sea level and typical surge information around the coastline of Wales under present day conditions. This is a specialist dataset which informs on work commenced around the coast ranging from coastal flood modelling, scheme design, strategic planning and flood risk assessments. The dataset contains the following layer components: - Extreme Sea Level Values: Extreme sea levels for a range of return periods - Extreme Sea Level Confidence Level: Confidence intervals providing allowances for uncertainty - Estuary Boundaries: Inland estuarine boundaries of the extreme sea levels - Surge Shape Locations: Reference to surge shape appropriate for each Class A gauge site and where to apply it - Tide Gauge Locations: Location of gauging stations
