10 sie 2021 · Disastrous river floods directly affect, on average, 125 million people annually, by evacuation, homelessness, injury or death 103, and have a wide range of direct impacts and indirect impacts...
Definition. Riverine flooding occurs when water levels in rivers rise above their banks, causing overflow into surrounding areas. This type of flooding can result from prolonged rainfall, rapid snowmelt, or ice jams, leading to significant impacts on both natural ecosystems and human infrastructure.
These floods are called riverine floods. Heavy rain, a broken dam or levee, rapid icemelt in the mountains, or even a beaver dam in a vulnerable spot can overwhelm a river and send it spreading over nearby land. The land surrounding a river is called a flood plain.
Riverine floods occur when rivers overflow their banks due to excessive rainfall, rapid snowmelt, or obstructions in the river system. These floods can lead to significant damage to infrastructure, homes, and ecosystems, making them a major concern in flood management and disaster response.
Drivers of fluvial flood: Fluvial (riverine) flooding primarily results from an extended precipitation event that occurs at, or upstream from, the affected area. It can also occur when traditional flood-control structures, such as levees and dikes, are overtopped (NOAA, no date).
6 lip 2022 · In our analysis, we aim to provide a global view of urban populations' exposure to floods and storm surges by using the GHSL data set. We include the spatial distribution and temporal evolution of the key flood hazard types: riverine floods and tropical storm surges.
