Culvert, Kilton Beck. That is a Culvert, in the south and Wales they are usually little things that you have to bend to walk into and where the flow hydraulics are formed by the restraints of the section. There is one in Mid Wales, Plynlimon, Hafren, afforested which is formed of corrugated iron and the regolith so it just stands under stress as a circular section on a steep stream and knowing the forces Welsh rivers produce from the 1968 Flood events which ripped out the partly prepared flume of the Hydrological Research Unit, HR Wallingford, the fact they remain there at all is a miracle. But then also they were just forest industrial roadways for heavy truck to bed the fragments down and Commission just repairs and grades as it goes. The picture shows something dependent on Rail grade and the spoil slip information is very useful to know. There is a concrete one just below Cullompton with flared approach and release, but I note this one at Kilton Beck has little release control to reduce scour. Thanks. Other pictures indicate the downstream outlet somewhat so I shall follow that through to see what flood issues may or may not be apparent, somewhat alike the Cornwall Landslide that formed a flood blockage recently.
