What is a large channel in the soil that carries runoff?

What is a large channel in the soil that carries runoff?

gully
A gully is a large groove, or channel, in the soil that carries runoff after a rainstorm.

What is a small channel of runoff?

Soil surface roughness causes may cause runoff to become concentrated into narrower flow paths: as these incise, the small but well-defined channels which are formed are known as rills. If runoff continue to incise and enlarge rills, they may eventually grow to become gullies.

What is the source of the runoff?

It comes from unabsorbed water from rain, snowmelt, irrigation or other sources, comprising a significant element of the water cycle as well as the water supply when it drains into a watershed. Runoff is also a major contributor to the erosion that carves out canyons, gorges and related landforms.

What are the different types of runoff?

There are three major types of runoff depending on the source: surface flow, interflow, and base flow.

What is a channel of connected grooves created by runoff?

Erosion

Question	Answer

————- may occur where a river meets an area of rock that is very hard and erodes slowly	waterfall

What is runoff in agriculture?

noun. the portion of rainfall that runs over agricultural land and then into streams as surface water rather than being absorbed into ground water or evaporating. pollution of the lagoon from pesticides contained in agricultural runoff from the surrounding area.

What is a runoff in geography?

Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Glaciers, snow, and rain all contribute to this natural runoff.

What is splash erosion in the soil?

Splash erosion is the first stage of the erosion process. It occurs when raindrops hit bare soil. The explosive impact breaks up soil aggregates so that individual soil particles are ‘splashed’ onto the soil surface.

What is rill flow?

[′ril ‚flō] (hydrology) Surface runoff flowing in small irregular channels too small to be considered rivulets.

When does runoff carry sediment into the river?

Runoff can carry a lot of sediment When storms hit and streamflows increase, the sediment moved into the river by runoff can end up being seen from hundreds of miles up by satellites. The right-side pictures shows the aftermath of Hurricane Irene in Florida in October 1999.

Why is runoff from agricultural land a problem?

Runoff from agricultural land (and even our own yards) can carry excess nutrients, such as nitrogen and phosphorus into streams, lakes, and groundwater supplies. These excess nutrients have the potential to degrade water quality. Why might stormwater runoff be a problem?

How is runoff related to the natural water cycle?

Runoff: Surface and Overland Water Runoff After a heavy rainfall you might see sheets of water running downhill…always seeking a stream it can run into, so it can continue to participate in the natural water cycle. When rain falls onto the earth, it just doesn’t sit there, it starts moving according to the laws of gravity.

What kind of streams carry water during wet times?

As surface runoff moves downslope, it concentrates in low areas and forms small stream channels. These are referred to as ephemeral channels that only carry water during rainfall runoff. Downstream from ephemeral channels are intermittent streams, which carry water during wet times of the year.
