Description of practice

Gully rehabilitation serves to mitigate gully development or rehabilitate degraded lands. Frequently the aim is to reduce surface water flow velocity and/or protect gully banks and heads through construction of checkdams. While interventions do have on-site effects, they are often undertaken with off-site interests in mind.

Examples of how to use gully rehabilitation Further information
(see Note below)

AMP06 01

Check dams from stem cuttings

Stem cuttings from trees that have the ability to strike root are used to rehabilitate gullies. These living barriers retard concentrated runoff and fill the gullies gradually with sediment.

AMP06 02

Gully control by plantation of Atriple

Gullied slopes are rehabilitated  by a plantation of Atriplex halimus fodder shrubs. The treated area is fenced off to facilitate plant growth and diversity.

AMP06 03

Filling gullies with vegetative structures

Barriers of willow branches and live mulberry cuttings are used to trap loess soil eroded by runoff to reclaim and infill eroded gullies.

AMP06 04

Gully rehabilitation using gabions and vegetative cover

Gabions with plantations of spanish drok (Spartium junceum L) are used to stabilize a gully.

AMP06 05

Gully control through silt fences, erosion blankets and brush packing

Gullies with active erosion are rehabilitated by re-sloping the banks of the gully to manage the energy of the water entering the system. Bare soil is protected from erosion by covering it with erosion blankets and brush packing.

AMP06 06

Permeable rock dams

Permeable rock dams are built in gullies serve to restore seriously degraded farmland and forest/rangeland. They slow the flow of floodwaters and spread the water over adjacent land.
