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.
Otherwise known as the DANA weather system, it has occurred for many years on Spain’s Mediterranean coast but scientists believe it is being made increasingly worse by climate change.
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 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.
In the 12 hours it took for the regional government's shelter-in-place order to come through, waters running through the usually dry Poyo ravine - the epicentre of the flooding - had surged to ...
Follow our live coverage of Spain floods. Rescue workers are facing challenges as they sift through the wreckage in search of survivors. Authorities have reported 202 fatalities so far, most of ...
Disastrous floods have been reported throughout the history of Valencia, from the 14th century up to the contemporary period. [5] The 1957 Valencia flood was caused by a three-day cold drop (Spanish: gota fría) (which usually leads to heavy autumn rains in Spain and France); it overflowed the banks of the Túria river and devastated the city of Valencia.
The full horror of the flash flooding in Spain began to emerge on Friday, just as new rainfall lashed southern parts of the country. The storm has killed at least 205 people, with 202 of those in ...
