Information

Success of soil conservation works in reducing soil erosion rates and sediment yields in central eastern Australia.

Level 1 General description

Purpose:

The purpose of this paper is to determine, from a review of the available information, whether soil conservation works reduce both on-site erosion rates and off-site sediment yields in central eastern Australia.

Methods (brief)

The published work on the effects of soil conservation works on reducing soil erosion rates and sediment yields in Australia was reviewed.

Three spatial scales were analysed:

(a) soil erosion rates on plots;

(b) sediment yields from small drainage basins (up to 100 ha in area); and

(c) sediment yields from large drainage basins.

Key findings (brief)

Soil conservation works undertaken on small drainage basins greatly reduced sediment yields by decreasing upland soil erosion rates. However, large decreases in upland soil erosion rates often led to reworking of downstream temporary sediment storages which often maintained high sediment loads on the main streams.

Soil conservation works are capable of greatly reducing runoff, soil-loss rates and sediment yields from small basins which are highly impacted by agriculture and/or erosion. However, the highly variable Australian rainfall and runoff means that large, infrequent storms dominate soil erosion and sediment transport.

Location

Headwaters of the southern tributaries of the Murray-Darling River in New South Wales.
