Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and potential impact while improving resilience against flood events. As climate change has led to increased flood risk an intensity, flood management is an important part of climate change adaptation and climate resilience .
This type of flood may be a lahar and has happened at Hekla. From a glacier surge into a proglacial lake or at the end of the surge when the subglacial drainage system re-establishes itself. The 1999 surge of Langjökull at its outlet glacier of Eystri-Hagafellsjökull was into a lake which then flooded downstream.
In geomorphology, an outburst flood—a type of megaflood—is a high-magnitude, low-frequency catastrophic flood involving the sudden release of a large quantity of water. [ 1 ] [ 2 ] During the last deglaciation , numerous glacial lake outburst floods were caused by the collapse of either ice sheets or glaciers that formed the dams of ...
River flooding can last days and sometimes weeks, unlike flash flooding. Just 6 inches of moving water can sweep people off their feet, 12 inches can carry away most cars, and 2 feet of moving ...
A cloudburst is an enormous amount of precipitation in a short period of time, [1] sometimes accompanied by hail and thunder, which is capable of creating flood conditions. Cloudbursts can quickly dump large amounts of water, e.g. 25 mm of the precipitation corresponds to 25,000 metric tons per square kilometre (1 inch corresponds to 72,300 ...
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
The Channeled Scablands are a relatively barren and soil-free region of interconnected relict and dry flood channels, coulees and cataracts eroded into Palouse loess and the typically flat-lying basalt flows that remain after cataclysmic floods within the southeastern part of Washington state.
A flood caused by a glacial lake outburst flood on 13 December 1941 killed an estimated 1,800 people along its path in Peru, including many in the town of Huaraz. The cause was a block of ice that fell from a glacier in the Cordillera Blanca mountains into Lake Palcacocha. This event has been described as a historic inspiration for research ...
