. . . "The Darent is a Kentish tributary of the River Thames. Bartholomew's Gazetteer (1951) demonstrates that Darent means \"clear water\". Considering that it runs on a bed of chalk (calcium carbonate) and its springs rise through chalk, this is not surprising. The word 'Darenth' is frequently found in older books and maps [incorrectly] describing the river. Darenth Parish (through which the river flows) derives its name from a Celtic phrase 'stream where oak-trees grow'."@en . "32186.9"^^ . . "River Darent"@en .
