Flood stage is the water level, as read by a stream gauge or tide gauge, for a body of water at a particular location, measured from the level at which a body of water threatens lives, property, commerce, or travel. [1] The term "at flood stage" is commonly used to describe the point at which this occurs.
Applied to various potential channel configurations and flow rates, a reach model can contribute to selecting an optimum design for a modified channel. Various reach models are available as of 2015, either 1D models (flood levels measured in the channel) or 2D models (variable flood depths measured across the extent of a floodplain).
Flood management is a broad term that includes measures to control or mitigate flood waters, such as actions to prevent floods from occurring or to minimize their impacts when they do occur. [4] [5] Flood management methods can be structural or non-structural:
The first routine measurements of river flow in England began on the Thames and Lea in the 1880s, [2] and in Scotland on the River Garry in 1913. [3] The national gauging station network was established in its current form by the early 1970s and consists of approximately 1500 flow measurement stations supplemented by a variable number of temporary monitoring sites.

Flooding can strike in seconds or days in various forms, each with its own life-threatening potential. However, all types of flooding should be taken seriously. "Sometimes people are not taking ...
A flood risk assessment (FRA) is an assessment of the risk of flooding from all flooding mechanisms, the identification of flood mitigation measures and should provide advice on actions to be taken before and during a flood.
The flow of water through the planet’s nearly 3 million rivers is changing rapidly, with potentially drastic implications for everything from drinking water supplies to flood risks, according to ...
As more of the world's population settles on flood plains, climate events become more extreme and Europe warms faster than the global average, what happened in Valencia underscores the need for ...
