Session C.22: Hydrodynamics

Greg Guthrie, Royal Haskoning DHV

What are you using this for or more specifically who do you feel will be using this and for what? We have looked at storm anatomies at a number of sites, looking at how variation of height / direction / period / water level over time alters coastal responses.

(1) Your forecasts currently use surge ensemble for the water levels. Do we need to couple these with wave ensemble predictions.

(2) Guidance on the need to use the full reconstructed 2D Spectra – use in forcing data to wave transformation models. Is there a benefit vs effort in using full spectra? Please comment on the benefits of using directional spread? Where might you suggest this is particularly useful?
