Protection of Communities
When more homes, shops and infrastructure are threatened by the effects of flooding, then the benefits of greater protection is worth the additional cost. Temporary Flood Defenses can be constructed relatively quickly in certain locations and provide protection from rising flood waters.
Rivers running through large urban developments will often have been controlled and channeled. These channels or canals will have a fixed capacity and if flood water flows exceed this capacity then the city will flood. Over time defenses will have been constructed to minimize the effects, and this will generally be through raising the sides of the river channel with embankments, walls or levees. The large number of people and huge value of infrastructure at risk in cities, means that protection works of high cost can be justified.
