Queensland Contour Banks Designing Erosion Control Contour Produced by the soil conservation service, nsw, australia around 1990. saved here for archival, historic and special interest purposes. This chapter of the soil conservation guidelines for queensland details how to design, build and maintain contour banks that remain stable and divert water effectively, without interfering with practices such as controlled traffic farming.
Queensland Contour Banks Designing Erosion Control Contour Thousands of miles of contour banks have been built in western australia, and most of this earthmoving has been done by tractor and disc plough* or by road grader. this article describes the technique recommended for bank construction with the road grader. When the starting point of the first contour bank has been determined, calculate the starting point of the next contour bank by using the formula (% s 3 2) 13 as described. Contour bunding involves constructing small barriers across slopes to reduce runoff and soil erosion. the document provides formulas to calculate the vertical interval between bunds based on land slope and rainfall zone. Contour banks help to prevent gully erosion, the most spectacular type of erosion. this document describes design and construction of graded contour banks.

Bund is an earthen embankment constructed to control runoff and minimizes soil erosion by reducing the length of slope. (i) contour bunding is most popular mechanical measure to control soil erosion and conserve moisture in arid and semi arid areas with high infiltration and permeability. Contour banks are earthen banks constructed at intervals across a slope to intercept and channel runoff into waterways or natural depressions. they have a slight gradient which is close to the natural contours of the land. Basic principals and techniques to construct broad based banks. video produced the soil conservation service, nsw around 1990. saved here for historic, archival and special interst. This chapter of the soil conservation guidelines for queensland discusses how to design diversion banks, which can be used to protect vulnerable land or infrastructure from surface water flows.
