Urban flooding is the inundation of land or property in cities or other built environment, caused by rainfall or coastal storm surges overwhelming the capacity of drainage systems, such as storm sewers. Urban flooding can occur regardless of whether or not affected communities are located within designated floodplains or near any body of water. [1]
The same report predicted that global warming of 2 °C would expose roughly 1-4 billion people to water stress. This would depend on regional patterns of climate change and the socio-economic scenarios. [8]: 558 On water scarcity which is one factor in water insecurity the report finds 1.5-2.5 billion people live water scarce areas.

If there is a flood warning or heavy rainfall in your area, do not get your car, Sorensen warns, adding: “That’s the No. 1 thing.” Cars can easily be swept away by flash flooding.
The mathematical model is the 2D shallow water wave equation. As such it cannot resolve vertical convection and consequently not breaking waves or 3D turbulence (e.g. vorticity). All spatial coordinates are assumed to be UTM (meters). As such, ANUGA is unsuitable for modelling flows in areas larger than one and half UTM zones (9 degrees wide).
Multiple countries and organizations have declared a water crisis. Water is a finite resource that is shared between nations, within nations, multiple interest groups and private organizations. Roughly 50% of all water available is located between two or more nation states. [87]
