Yes it is obviously something is worthy of research and hence why I proposed the question. Could be a good PhD for somebody.
Having lived near, and on one occassion in, the Thames for many years I have to say flooding is quite an amazing thing.
The trouble with using flood deposits from flood plains is that all they tell you is that there was a flood on a meadow and not how high the actual flood was. In the case of water meadows they were deliberately flooded in any event. In the case of Goring flooding of meadows is an annual event.
Interestingly The Churches of Goring and Streatley are located just above the 100 year flood zone. Clearly there is an effect of building on the flood plain on the extent and return period of a flood but these will be both increased. Thus comparing the historic data with modern data may given a truer indication of the real effect of these.
In some areas the flood plain has not being built on to any great degree on the scale of things and this can then be used to compare the natural flooding with the modified flooding.
What is interesting at the moment on Thames is the extent to which the old bridges are not being flooded as at Dorchester and Wallingford.
On the other place is a report on how the HER have been affected by the flooding.
