This course describes the formation, control, and mitigation of gullies.
This course describes the formation, control, and mitigation of gullies. The severity of gully development depends on a number of factors including soil type, vegetation, rainfall, concentrated flow, and human disturbances. Gullies can erode hill slopes 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. To best select a design alternative, the desired results of the landowner must be understood along with the character of the gully and its potential impacts.
Topics: Classical gullies and ephemeral gullies Gullying processes in streams Issues contributing to gully formation or enlargement Gully erosion control Treatment Options for Gullies Gully Plugs, Debris Dams, Rock Check Dams Grade Control Structures Rock Treatments, Water Diversions, Grassed Waterways Fertilization and Land Reshaping
Intended Audience: This course is intended for Civil, Environmental, Land Development, Water Resources, Hydraulic, and other engineering professionals whose job description requires a general knowledge of controlling and mitigating gullies.
