Withernsea (East Riding of Yorkshire) 1 Sep., 2018
Keywords: Offshore wind power, Coastal erosion
I visited Withernsea to see offshore wind turbines and to observed coastal erosion (Fig. 1).

Many wind turbines were lined up off the coast of Withernsea (Fig. 2). I could see at least hundred turbines with sevral hundred of meters interval.

It seems to be difficult to fishing in the area. In Japan, inshore
fishery is active in many coastal areas so coexistence with fishery will
be one of the subjects for Japanese offshore wind industry, I think.
The coast of Withernsea is protected from coastal erosion by levee and large stones (Fig. 3).

On the other hand in coast around the town, there are no levee and severe coastal erosion is in progress (Fig. 4). Some houses and roads were lost due to the erosion (Fig. 5).

The coastal cliff is consisted of till and we can find many landslide surfaces (Fig. 6). But there are no landslide deposits or talus in the bottom of the cliff. They will probably be eroded easily by wave during high tide when the beach in front of the cliff is submerged. In Japan with micro-tide, most of beach is not submerged entirely even during high tide. I think I need to pay more attention to tidal range when I discuss about coastal erosion.
