Geology
A typical river valley geological make up
Upstream
The upstream section of the site from Redhill to Water Lane Farm (Brecon Close BH10 7DX) has a geology typical of river valleys, comprising of alluvial deposits.
Downstream
From Redhill downstream, there is a very narrow band of alluvium along the river channel that then givesway to valley gravel.
At Redhill, where the ground rises quite steeply away from the river, the geology is typical of that underlying local dry heathland. Here there are Bagshot Beds of sand, brickearth, pipe-clay and lignite, which extend almost down to the river itself.
