Sinking
The sinking of the Danube at the Immendingen railway bridge
Under Versinkung refers to the rapid penetration of water into larger openings ( Karst , gap , sinkhole ) of the earth's surface. In this occurs turbulent flow on.
In contrast, there is seepage , i.e. the slow penetration of water in a laminar flow into the pores of the soil ( soil structure ) through infiltration .
A typical case of subsidence is the submergence of surface rivers into underground rivers in karst areas . At the end of the underground section, the water reappears as a source . The most famous sinking is the Danube sinking .
Underground watercourses do not count as groundwater because of their noticeable flow speed .
