Synonym: Pulsating spring landscape

A tidal spring is also known as a periodic spring because its flow volume is characterised by non-seasonal periodic changes. These periodic changes can be regular or irregular and are a result of the siphoning action in the karst hydrological system. Therefore, these springs are sometimes called karst siphon springs. These tidal springs are found in both southern and northern China, mainly in Guizhou, Yunnan, Guangxi and Sichuan Provinces. An example is the ‘Sanchaoshui (Three Tides)’ in northwestern Xiuwen County along the lower section of the Maotiao River. These spring groups are located in middle Upper Cambrian laminated dolomite strata, and the elevation of the spring outlet is at 1,260 m. In year 11 of Daoguang in the Qing Dynasty (1831 AD), a crescent pool was built at this location, and the spring water began to flow from the carved stone dragon’s mouth. The flow splashed strongly during high tides but trickled weakly during low tides.
