A network of rills, gullies, streams, and rivers in an area.
A network of rills, gullies, streams, and rivers in an area.
Rills and gullies are both landforms formed by erosion caused by flowing water. The main difference is in their size and scale: rills are smaller and shallower, while gullies are larger and deeper. Gullies tend to be more pronounced and have steeper sides compared to rills.
The network of rills, gullies, streams, and rivers in an area is often referred to as a watershed or river basin. This system of interconnected waterways ultimately drains into a common body of water, such as a lake or ocean.
Precipitation -- rain and snow cause flowing water in nature.
Over time, rills expand and join together causing gullies.
Rills are small channels formed by the erosion of soil by flowing water, typically seen on hillslopes. Gullies are larger channels formed by water flow, often resulting from the continuous erosion and enlargement of rills. Both rills and gullies are formed by the process of water cutting into and carrying away soil and sediment.
sheet erosion, rills, gullies
A rill is a much smaller channel. A gully was once a rill that got broader and deeper. There are another differences too: 1- Ratio of width to depth: In gully that ratio is approximately 1:1 but in rills width is greater than itsdepth. 2- In agricultural activities, rills can be removed but gullies can not. 3- In specific area, number of rills are higher than gullies. 4- sediment production of gullies is much higher than Rills.
floodplain
Tiny rills enlarge to form gullies, which join to form a stream.
Rills are small, narrow channels or grooves created by erosion from running water on the surface of the Earth. They are typically found on sloped terrain and can contribute to further erosion if not properly managed.
