Flood

A flood is an overflow of water that submerges land which is usually dry. The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water. In the sense of "flowing water", the word may also be applied to the inflow of the tide.

Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rainwater on saturated ground in an areal flood. While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, these changes in size are unlikely to be considered significant unless they flood property or drown domestic animals.

Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. While riverine flood damage can be eliminated by moving away from rivers and other bodies of water, people have traditionally lived and worked by rivers because the land is usually flat and fertile and because rivers provide easy travel and access to commerce and industry.

Flooding (Australian football)

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.

History

When Australian Football took to the parks around the colony of Victoria in 1858, there were no rules regarding player positions. Even today the rules only declare that a maximum of four per side is allowed in the centre square at the ball-up (ruck, rover, ruck-rover and centre), with all other players free to position themselves as they see fit. In early years this resulted in a pack of players moving with the ball up and down the field trying to get a clearing kick into space that the pack would then run into and repeat the process. Such a process is still evident in some junior leagues (the under 8 years old children) and is known as "beehive football". It was not until 1898 that player positions became regular thanks to Essendon's now famous positions of players around the field. The positioning provided many lopsided contests against teams trying to play pack football, such as beating St Kilda 10.11 (71) to 1.9 (15) on July 23 and Melbourne 11.9 (75) to 2.8 (20) on August 1 in 1898. Other teams mimicked the idea and the "lines of three" quickly became, and still is, the norm.

Flooding (psychology)

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.
