Additional Physical Format: Online version: Low-cost gully erosion control. [Washington, D.C.]: Soil Conservation Service, U.S. Dept. of Agriculture, . Considered the worst stage of water erosion, 29 million ha in Africa is said to be affected by gully erosion and with a total of t ha -1 yr -1 in Ethiopia which is considered to experience.
As seminal reviews of gully erosion processes have already been published elsewhere (Poesen et al., ; Valentin et al., ), this paper seeks to provide additional context of selected gully erosion topics that emerged during and after this symposium.
These topics include technology transfer, disciplinary fragmentation, erosion prediction Cited by: 7. TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis Cost-Effective and Sustainable Road Slope Stabilization and Erosion Control presents information on cost-effective and sustainable road slope stabilization techniques, with a focus on shallow or near-surface slope stabilization and related erosion control methods used on low-volume roads.

It was estimated that gully erosion supplied between 29 and 44% of catchment sediment yield from % of catchment area, of which 85% was derived from gully wall erosion.

Wirth, Herbert Hoover, and United States. Agricultural Research Service (page images at HathiTrust).
Once the gully gradient is stabilized, vegetation can establish and gully banks can stabilize. Because of sediment accumulation in the gully above the structures, the storage capacity of the channels increase, channel gradients decrease, and thus peak flows decrease. In practice, the control of gully erosion is difficult and expensive.
It is a common conception that gully control means building check dams, planting trees, plugging gullies with brush, or directly applying to a gully some other individual control measure.
This way of thinking focuses attention on devices that stop gullies rather than on ways of farming that prevent gully erosion. A broad, coordinated attack is in general necessary to keep gully. Collapsed gully erosion constantly plagues the sustainability of rural areas in China. To control collapsed gully erosion, an ecological and economic approach, which uses tree plantation to gain economic benefits and control soil erosion, has been widely applied by local governments in Southern China.

However, little is known about the economic feasibility of this new by: 5. Vegetation is not a panacea for controlling erosion and must be considered in light of site-specific characteristics.
When vegetation is combined with low-cost building materials or engineered structures, numerous techniques can be created for streambank erosion control. This documentFile Size: 2MB. This chapter discusses gully erosion monitoring. Gullies are permanent erosional forms that develop in many parts of the world, particularly in arid and semi-arid environments.
Gullies function as sediment sources, stores, and conveyors that link hillslopes to downstream channels. NORTH EAST DOWNS EROSION DAY 19 TH NOVEMBER North East Downs in conjunction with SQ Landscapes held a workshop and field day to demonstrate to landholders the method used for a low cost gully repair at Ballon Pastoral Co that can easily be replicated on other properties with very little outlays.
Introduction. Soil erosion is a significant environmental issue of common concern in the world today, serious water and soil loss resulting from what has become one of the main factors restraining local economic development [1–3].As a common type of soil erosion, though not of as wide range as surface erosion, however, because of its large amount and fast speed, gully Cited by: SHORELAND PROJECTS Erosion Control Ordinances and Community Education Community-Wide Stormwater Management Gully and Streambank Erosion Control Shoreland Landscaping Living with Shoreland Wildlife Shoreland Environment: Putting the Pieces Together Shoreland References ALGAE CONTROL Nutrient Reduction Strategies Biological Controls in the Lake.
Gully erosion constitutes the most severe form of soil erosion in arid and semiarid landscapes. Illustrated by selected examples, this chapter gives an overview of gully-erosion studies employing SFAP at > 30 sites during the last 25 years.
2D and 3D change quantification based on the detailed maps and DEMs provides information on the. To combat this disaster, erosion control is necessary and must be technically suitable, cost-effective, people-oriented, sustainable and environmentally safe.

Vetiver System for Soil Erosion Control in Ethiopia.A slide show put together by Alemu Mekonnen in gives quite a good idea of the soil erosion and soil loss that Ethiopian farmers are faced with, and how the Vetiver System can help mitigate the problems.

Kwaad, physical geographer Home Contact Other websites by the author: Images of soil erosion - Ephemeral gully erosion - Soil erosion control in Europe Introduction The website is a means of rapidly locating information on the economic costs of soil erosion.
Gully erosion can be severe in semi-arid climates and the benefit/cost of gully control needs to be considered. Successful but expensive gully conservation like the Australian example shown in Plate might not be suitable for third world countries.
This fully revised edition of a handbook on soil conservation gives information on recent advances, including the greater emphasis on sound land use and farming methods; the importance of involving the farmer at all stages; and the need for low-cost, low-labour methods.
It is shown how research, theory and practice can be applied in developing countries. Soil bioengineering for erosion control is not a method that imposes manmade structures on the site at the expense of existing native plant materials.
Control of bank erosion can be accomplished in several ways, such as the use of rock-fill, which, though efficient, is quite expensive, precluding its use extensively along river by: 3.

We focus on the use of restoration and management techniquesFile Size: 3MB. EXAMPLE: If a road culvert is to last 25 years with a 40% chance of failure during the design life, it should be designed for a year peak flow event (i.e., year recurrence interval).
When streamflow records are not available, peak discharge can be estimated by the "rational" method or formula and is recommended for use on channels draining less than 80 hectares ( acres).
Gully erosion is erosion resulting in a relatively deep incision of the soil surface caused by concentrated overland runoff. Erosion control mats, nets or blankets are simply coverings that.
These resources explain simple and cost-efficient methods to help slow flow and start rebuilding gully floors through building Porous Check Dams (PCDs). PCDs are a low-cost and low-risk erosion control method recommended by CSIRO in their 'Gully Toolbox' kit.
GTZ collaborates with the Erosion Control Bureau of Tibet Autonomous Region and other partners implementing erosion control activities in two catchments of Eastern Tibet.
As shown in Figure 1 there are a number of causes and effects to land degradation in the selected catchments.
