sheet flow

[′shēt‚flō]
(hydrology)
An overland flow or downslope movement of water taking the form of a thin, continuous film over relatively smooth soil or rock surfaces and not concentrated into channels larger than rills.

When I began working on this project three years ago, there was a single map of ice sheet flow that was made using data collected over 10 years, and it was revolutionary when it was published back in 2011.
Note where sheet flow is the most forceful during storms on your property, Slovensky recommends.
The study proposes that due to this mechanism, rising global temperatures could increase the volume of surface meltwater flowing into the subglacial lakes, which may "act to release the pressure at the ice sheet base, meaning that if they drain more frequently in the future, they may actually result in slower ice sheet flow overall," says Palmer.
Our discovery will help us predict more accurately how supraglacial lakes will affect ice sheet flow and sea level rise as the region warms in the future," lead author Laura Stevens wrote in a Woods Hole press release.
Before this rain, vineyard ponds that are filled by only sheet flow were nearly dry.
Panel heaters are mounted both perpendicular and parallel to sheet flow direction, allowing precision zone profiling from front to back and side to side.
When it rains hard on the Jornada, the water runs across the soil surface as sheet flow, but the accumulating biomass dams the flow.
From the pump discharge hose, flow moved as sheet flow via gravity through the prefabricated channel across a series of baffles consisting of stacked, weighted sediment tubes placed perpendicular to flow across the entire width of the channel.

In small depressions and upslope of rocks and plants, the soil moisture would linger longer than in areas where sheet flow went unchecked.
In sheet flow, [OMEGA] = [rho]gSq, where [rho] is the density of water, g is the acceleration due to gravity, S is the slope of land element (the sine of the angle of slope), and q is the water flux.
Zone 3 is managed to provide spreading of concentrated flow into sheet flow and to remove sediment and sediment-associated pollutants.
