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.
Floods often cause damage to homes and businesses if these buildings are in the natural flood plains of rivers. People could avoid riverine flood damage by moving away from rivers. However, people in many countries have traditionally lived and worked by rivers because the land is usually flat and fertile. Also, the rivers provide easy travel ...
Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. 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 ...
From the ecological perspective, the most distinctive aspect of floodplains is the flood pulse associated with annual floods, and so the floodplain ecosystem is defined as the part of the river valley that is regularly flooded and dried. [19] Floods bring in detrital material rich in nutrients and release nutrients from dry soil as it is flooded.
Climate change is already making extreme flooding more frequent and intense and by 2050 100-year flood events are projected to occur at least twice as frequently as today across 40% of the planet.
It typically causes economic damage. How bad the damage is depends on how well people are prepared for disasters and how strong the buildings, roads, and other structures are. [2] Scholars have been saying that the term natural disaster is unsuitable and should be abandoned. [3] Instead, the simpler term disaster could be used. At the same time ...
People kayaking down a street in Mid-City New Orleans following flooding in 2019. There are several types of urban flooding, each with a different cause: Pluvial (flooding caused by heavy rain), Fluvial (caused by a nearby river overflowing its banks), and; Coastal flooding (often caused by storm surges).
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.
