Description :
Spectacular bed forms, eroded by flood flows, are a feature of the bare rock terraces and channels of some rivers cut into granitic rock in the districts of Salamanca, Cáceres and Badajoz, W Spain. The bed forms comprise a range of pothole types which individually represent various stages in the evolution of mature potholes. Pothole evolution reflects the hydrodynamics of the erosion, by high velocity flood flows, of bedrock. They evolve in time and in concert with the evolution of the landscape.
