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 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 ...
Other rivers arising near the Chilterns include the Mimram, the Ver, the Gade, the Bulbourne, the Chess, the Misbourne and the Wye. These are classified as chalk streams, although the Lea is degraded by water from road drains and sewage treatment works. [9] The Thames flows through a gap between the Berkshire Downs and the Chilterns.
About 85% of the world’s chalk streams are found in England, of which more than three quarters are not in good health, according to a report by the Worldwide Fund For Nature. Follow Norfolk news ...
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 ...
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 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.
It rises in the Berkshire Downs near its namesake village of Lambourn and is a tributary of the River Kennet, which is itself a tributary of the River Thames. The river is a 28.9-hectare (71-acre) biological Site of Special Scientific Interest [ 1 ] [ 2 ] and Special Protection Area under the European Union Directive on the Conservation of Wild ...
