Soil erosion by wind - Dust Storm Index (DSI)

National Monitoring and Evaluation Framework

In 2005 the National Land & Water Resources Audit (NLWRA), through the National Committee for Soil and Terrain (NCST), convened four expert panels to advise on the monitoring of: soil acidification, soil carbon changes, water erosion and wind erosion (McKenzie & Dixon 2006). Later in 2006 the NLWRA commissioned a series of trials of the recommended approaches to (more)...

Monitoring Wind Erosion in Australia

Monitoring wind erosion risk by roadside survey in the wheatbelt of Western Australia

This document reports on the testing of roadside survey as a means of monitoring wind erosion, or more accurately, the risk of wind erosion. In testing the approach this document provides a prototype that others may follow and improve upon. The survey approach follows that of Andy McCord (Appendix 1 and McCord 2005) which has been operating for some time in South Australia and this report is a trial of that system. Appendix 1 product number: (more)...

Controlling evaporation losses from farm dams

National Program for Sustainable Irrigation Fact sheet 2005/4

As much as 40% of water stored in a farm dam can be lost through evaporation, depending on the depth of the dam and its surface area. Dam design can significantly decrease evaporation by reducing the surface area to volume ratio (deeper, narrower dams) and planting windbreaks to provide shade and reduce wind turbulence. Over the years, a number of commercial products have also been developed to minimise water losses, including floating plastic covers and chemical products that change the (more)...
