Sometimes, it also refers to the fluvial action of rainwater flowing in a stream channel, including a flood, known as a pluvial flood, that is the direct result of excessive precipitation. [ 1 ] [ 2 ]
In geography and geology, fluvial sediment processes or fluvial sediment transport are associated with rivers and streams and the deposits and landforms created by sediments. It can result in the formation of ripples and dunes , in fractal -shaped patterns of erosion, in complex patterns of natural river systems, and in the development of ...
There is a delicate equilibrium that controls a river system, which, when disturbed, causes flooding and incising events to occur and produce terracing. [3] [4] Dating of these abandoned terrace surfaces (treads) is possible using a variety of geochronologic techniques. The type of technique used, however, is dependent on the composition and ...
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 .
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 ...
Fluvial terraces can be used to measure the rate at which either a stream or river is downcutting its valley. Using various dating methods, an age can be determined for the deposition of the terrace. Using the resulting date and the elevation above its current level, an approximate average rate of downcutting can be determined.
Fluvial processes form several channel patterns, including: Straight, which are found in the most tectonically incised/active areas. This is more of a hypothetical end-member, and are not often found in nature. Straight-type channels can be found at alluvial fans.
