His results demonstrate that the salient factor in aqueous soil erosion is the minimum length of overland flow necessary to produce enough runoff to effect erosion.
22.
A channel head forms as overland flow and / or subsurface flow accumulate to a point where shear stress can overcome erosion resistance of the ground surface.
23.
For example, when the soil is saturated, rainfall will stay on the surface _ " overland flow, " it's called _ and rush quickly into the main river.
24.
MIKE FLOOD can be expanded with a range of modules and methods including a flexible mesh overland flow solver, MIKE URBAN, Rainfall-runoff modeling and dynamic operation of structures.
25.
Overland flow is a stormwater runoff that begins as thin layer of water that moves very slowly ( typically less than 0.25 feet per second ) over the ground.
26.
Other processes that contribute to the formation, but that are of lesser importance, include overland flow of water caused by rain and the combined action of snow and wind.
27.
The quickest response times between rainfall and streamflow occur in urbanized areas where yard drains, street gutters, and storm sewers collect overland flow and route it to streams straightaway.
28.
Myers said he hopes the government of Uzbekistan in the next few days would open a key bridge to enable a greater overland flow of humanitarian relief into northern Afghanistan.
29.
Stubble cover in contact with the soil minimizes erosion from water by reducing overland flow velocity, stream power, and thus the ability of the water to detach and transport sediment.
30.
"' Surface runoff "'( also known as "'overland flow "') is the flow of water that occurs when excess stormwater, meltwater, or other sources flows over the soil erosion by water.
