New hope on gully erosion

(1978) New hope on gully erosion. Farmer and Grazier, 1 June 1978. [Publication] [Special Collections]


Article discusses a Narrogin Agriculture Department trial has come up with a new design for blocking gully erosion with materials found in the immediate area.
Department officers devised a silt trap which was aimed as a temporary 'first-aid' measure in gullies facing problems.
Sediment causes damage once a gully starts to fall away by silting dams and fences and dumping sand on creek crossings and roads.
The Narrogin team was facing the problem of how to keep the land intact until a more permanent arrangement could be installed, although the trial trap is still intact after six years.
Department officer, T. Negus said that silt dams had been used in many countries to deposit soil in the gully with the hope to stabilise this with vegetation coverage.
The team came up with a completely successful system using brushwood, or dryandra scrub laying this lengthwise in the gully for about 15 metres with the gully filled to ground level.
Mr. Negus explains that the brushwood seemed to reduce the water velocity sufficiently to cause the sand to settle among the branches.
