Foudry Brook - Geology and Hydrogeology

Geology and Hydrogeology

Chalk is the major aquifer in the Berkshire area. In the areas underlying Foudry Brook an overlying layer of clay and sand confines the chalk

Foudry Brook has the typical characteristic of clay catchment rivers. It has a very variable flow rates, a low base flow component and a ‘flashy’ nature; it responds quickly to extreme rainfall events due to the impermeable nature of the clay over which it flows and the resulting high surface water runoff.
