RIVER TILLINGBOURNE. The River Tillingbourne is just 11 miles long running along the south side of the North Downs to join the River Wey at Guildford. Its source is near Tilling Springs to the north of Leith Hill and the catchment is situated on sandstone which has a low rate of weathering.ishing Breaks offer brown trout dry fly and nymph fishing in the county of Surrey. Surrey might not at first glance be much of a river county but it actually has nineteen classified rivers, including the River Thames.
BURBAGE VALLEY, DERBYSHIRE Burbage valley is 8km north-west of Sheffield. The valley is drained by Burbage brook, a tributary of the R. Derwent.The valley has been carved through two different types of rock - 'millstone grit' and 'shale'.Within this small area we can explore the range of factors which affect the work of rivers.. Burbage brook rises on a moorland plateau. Beneath the surface are impermeable gritstone rocks, so this moorland is very wet. The poor drainage means that vegetation does not rot easily, and a layer of peat has formed over the surface.
