The products of chalk weathering are dissolved in rainwater and are transported in stream flow. Chalk streams transport little suspended material (unlike most rivers), but are considered "mineral-rich" due to the dissolved calcium and carbonate ions. The surface water of chalk streams is commonly described as "gin clear".
The River Chess is a chalk stream that rises near Chesham in the Chiltern Hills, and flows for 11 miles (18 km) through Buckinghamshire and Hertfordshire to its confluence with the River Colne in Rickmansworth. The Chess, along with the Colne and Gade, gives rise to the name of the district of Three Rivers.
The River Dour is a chalk stream in the county of Kent, England. It flows from the villages of Temple Ewell and River between which is a neighbourhood served by a railway station, Kearsney. It is roughly 4 miles (6.4 km) long. It originally had a wide estuary on the site of modern Dover, although today it flows into the Dover Harbour through a ...
The river rises at Mead End near Bowerchalke and flows 1.2 miles north through the Chalke Valley to join the Ebble at Mount Sorrel, just upstream of Broad Chalke. It provides a steady, year-round flow of water; above the junction the Ebble is a winterbourne. A typical chalk stream, the Chalke is noted for its brown trout and fish farms.
The Gypsey Race rises in the Great Wold Valley [4] through a series of springs and flows intermittently between Duggleby and West Lutton where it runs underground in the chalk aquifer before re-surfacing in Rudston. It has been known during very wet conditions for the stream to re-appear at Wold Newton [5] some 4.3 miles (7 km) north-west of ...
Other examples include the Alkham Valley near Dover, and the Hartley Bottom and Fawkham valleys near Dartford in north Kent. [1] There are many examples of limestone dry valleys in the Peak District and the Yorkshire Wolds. A notable example is the valley of the River Manifold which is dry, except in spate, from Wetton south for several miles.
The Nailbourne near Bishopsbourne on 22 July 2006. Even when there is no water in the stream it is still a haven for wildlife. The Little Stour starts at the springs near Well Chapel, Bekesbourne, after the watercress beds the Nailbourne joins the Little Stour (when it is running) and then joins with the Great Stour at Plucks Gutter near West Stourmouth.
A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.
