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.
Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type (i.e. flood control) and of the non-structural type. Structural methods hold back floodwaters physically, while non-structural methods do not.
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:
Recurrence interval = +. n number of years on record; m is the rank of observed occurrences when arranged in descending order [3]. For floods, the event may be measured in terms of m 3 /s or height; for storm surges, in terms of the height of the surge, and similarly for other events.
These curves are commonly used in hydrology for flood forecasting and civil engineering for urban drainage design. However, the IDF curves are also analysed in hydrometeorology because of the interest in the time concentration or time-structure of the rainfall , [ 2 ] [ 3 ] but it is also possible to define IDF curves for drought events.
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 ...
