June 27. Gully traps; ; silt and sludge boxes.- The middle section W is formed in one with a trap P and also with the base Q, or it may be in a separate piece. It is formed with a shoulder g to support a silt box E having the middle portion e of the bottom made as a ...
15.8 years; Fig.6) with no less than the present litter input. By extending the surface SOC residence time up to 24.4 years, the surface SOC content would have the potential
The soil bunds thus created trap not only soil, but also water. During heavy rain storms this can lead to sudden accumulations that create breakages in the bund. When one bund breaks, this often creates a domino effect in which water flows further concentrate, and multiple bunds are broken...
19,108. Leach, J. E. Sept. 5. Traps.-To prevent the escape of sewer gas during the removal of the silt box and cap C of the traps described in Specification No. 17,593, A.D. 1900, and similar traps, a "teapot" trap B is fitted to the gully. It may be integral with the ...
Fine sediment yields (silt and clay) were reduced by 7 and 19% from the two treated gullies, respectively. The porous check dam deposits contained a lower percentage of the fine fraction than the parent soil. Significant regeneration of gully floor vegetation occurred, associated with trapping of...
Traps; silt boxes.-A gully trap in which the upper and lower parts are relatively adjustable and therefore adaptable to various street gradients comprises a cover C<1> having a wall d and a basin C having a partition a. The sides of both parts are cylindrical. The plates a, dare bolted...

Finally, according to the control targets, the comprehensive prevention and control idea of integrated blocking, retaining with draining was put forward, and the prevention and control engineering including check dam, silt-trap dam, unilateral protection embankment and V-type drainage groove were ...
Depending on the gully site conditions, the artificial forestation by reasonable assembly of arbor trees or mixed with shrub can rehabilitate the ecological environment while managing gully erosion. Although vegetation has an excellent potential to trap sediments, it cannot stop the upslope migration of...
