That bridge is 1. may be a natural bridge of bedrock normally formed outside a cave entrance by partial collapse leaving an isolated roof segment, as in the famous examples of rakov skocjan, slovenia. rock bridges may also occur inside caves due either surrounding phreatic dissolution or collapse between superimposed passages. another common type inside a cave is a span of false floor where sediment is washed from below, as at the bridge in gb cavern in the mendip hills [9]. 2. in a cave, a residual rock span across a passage [10]. 3. in water wells, an obstruction in the drill hole or annulus. a bridge is usually formed by caving of the wall of the well bore, by the intrusion of a large boulder, or by filter pack materials during well completion. bridging can also occur in the formation during well development [16]. see also natural bridge.?

GROUNDWATER CONTAMINATION IN KARST AREAS OF SOUTHWESTERN CHINA AND RECOMMENDED COUNTER MEASURES

Abstract:
Approximately 33% of China is karstic. The most extensive karst areas are in southwestern China and cover approximately 540,000 km2. Southwestern China hosts some of the most typical karst landforms in the world and has important high-quality karst water resources. Due to the rapid development of China, karst waters are threatened by various types of contamination. Detail field and laboratory investigations in five provinces including several cities in southwestern China were conducted in 2008 and 2009. Eightythree springs and underground rivers were surveyed and water samples collected from each for laboratory analyses for major ions. Four main types of karst aquifer contamination were identified based on contaminant sources: rural and agricultural pollution, pollution from urban development and industry, pollution from mining, and accidental groundwater pollution. Several representative instances for each type of contamination and their impacts on the environment are discussed in more detail. Contamination countermeasures of karst waters and a framework for overall management of karst water resources in southwestern China are provided.
