Flooding is a tactic used in the sport of Australian rules football. It involves the coach releasing players in the forward line from their set positions and directing them to the opposition forward area, congesting the area and making it more difficult for the opposition to score. It is commonly deployed to protect a lead, to stop a rout or as a counterattack tactic based on rebounding the ball to an open forward line. This is possible due to the lack of an offside rule or similar restrictions on players field movements.

The extreme defensive tactic is often bemoaned by spectators and generally regarded as "ugly" football.

Flooding is a form of behavior therapy based on the principles of respondent conditioning. It is sometimes referred to as exposure therapy or prolonged exposure therapy. As a psychotherapeutic technique, it is used to treat phobia and anxiety disorders including post-traumatic stress disorder. It works by exposing the patient to their painful memories, with the goal of reintegrating their repressed emotions with their current awareness. Flooding was invented by psychologist Thomas Stampfl in 1967. It is still used in behavior therapy today.

Flooding is a psychotherapeutic method for overcoming phobias. This is a faster (yet less efficient and more traumatic) method of ridding fears when compared with systematic desensitization. In order to demonstrate the irrationality of the fear, a psychologist would put a person in a situation where they would face their phobia at its worst. Under controlled conditions and using psychologically-proven relaxation techniques, the subject attempts to replace their fear with relaxation. The experience can often be traumatic for a person, but may be necessary if the phobia is causing them significant life disturbances. The advantage to flooding is that it is quick and usually effective. There is, however, a possibility that a fear may spontaneously recur. This can be made less likely with systematic desensitization, another form of a classical condition procedure for the elimination of phobias.

Flooding is a simple computer network routing algorithm in which every incoming packet is sent through every outgoing link except the one it arrived on.

Flooding is used in bridging and in systems such as Usenet and peer-to-peer file sharing and as part of some routing protocols, including OSPF, DVMRP, and those used in ad-hoc wireless networks.

(A) Counter-current annular flow

(B) Point of flow reversal

(C) Concurrent slug flow (or other flow)]]

Flooding refers to a fluid flow phenomenon whereby counter-current two-phase flow is reversed and runs concurrent in the direction of the initial gas/vapor phase flow when filling, or "flooding", a nuclear reactor core with coolant. This phenomenon is generally discussed with respect to a loss-of-coolant accident (LOCA). As this phenomenon proceeds, annular flow running counter-current begins as liquid water is inserted into the system. Then if conditions are correct, the frictional force at the gas-liquid interface begins to reverse the flow of the liquid. Finally, the flow of the liquid reverses, running concurrently in a slug (or other) flow regime. The significance of this phenomenon is that, if not properly designed for, it can present issues when trying to fill the core with liquid (the phenomenon works against gravity, forcing liquid out of the core).
