Flow stoppage, also known as STASIS, is a term used to describe a situation in which the flow of a liquid or gas is stopped or blocked. It can be caused by a variety of factors, such as a blockage in a pipe, a malfunctioning valve, or a lack of pressure. In some cases, it can even be caused by a natural disaster, such as an earthquake or flood. STASIS can have serious consequences, including damage to infrastructure and disruption of services.
