Gullies are commonly related to intermittent or ephemeral water flow, usually associated with localised intense or protracted rainfall events or snowmelt.

Apr 26, 2017 · Gullies are landforms created by surface runoff which erodes deep into the soil, especially on the hillside. Gullies are like wide ditches or developing valleys but are a few feet deep and wide.

Gullies can erode hillslopes and fill stream channels with sediment. Unchecked, they erode and deliver sediment through a variety of processes that cause loss in soil productivity, channel entrenchment, and headward expansion into the landscape.

This study instrumented eight gullies ranging in size from 36-90 m long, 2.4 to 9.5 m wide, and 0.9 to 3.0 m deep with weirs, stage recorders, and stormwater samplers to assess gully response to prescribed burning.

In the United States, however, gully manage­ ment has been successfully practiced on agricul­ tural lowlands at least since the 1930's, when conservation farming was introduced on a large scale. Farmers converted gullies into grassed waterways to serve the dual purpose of safe con­ veyance of surplus irrigation water and forage production.

5 days ago · The Ohio River is one of the most historically significant rivers in the United States, running 981 miles from Pennsylvania to its confluence with the Mississippi River in Illinois.

Sep 1, 2007 · The LiDAR maps of gullies are most distinct for wide, deep gully systems with steep headwalls. These tend to be older gullies that have deepened then widened. Gullies that have not penetrated to saprolite are often relatively narrow, shallow, and V-shaped and can be more difficult to detect, especially in their upper reaches.

gully, trench cut into land by the erosion of an accelerated stream of water. Various conditions make such erosion possible: the natural vegetation securing the soil may have been destroyed by human action, by fire, or by a climatic change; or an exceptional storm may send in torrents of water down the streambed.
