A pneumatic barrier is a method of containing oil spills. It is also called a bubble curtain. Air bubbling through a perforated pipe causes an upward water flow that slows the spread of oil. It can also be used to stop fish from entering polluted water. An other application of a pneumatic barrier is to decrease the salt-water exchange in navigation locks and prevent salt intrusion in rivers Abraham, G. Van der Burgh, P. De Vos, P. (1973) Pneumatic barriers to reduce salt intrusion through locks, Rijkswaterstaat Communications 17, URL Pneumatic barriers are also known as air curtains. The pneumatic barrier is a (non-patented) invention of the Dutch engineer Johan van Veen from around 1940 De Ingenieur, 7 maart 1941, URL
