Erosion

A remote sensing approach for mapping and classifying riparian gully erosion in Tropical Australia

Recent aerial and ground reconnaissance through the Gulf of Carpentaria has identified riparian gully erosion as one of the dominant contemporary sediment sources to many of the large rivers draining into the Gulf of Carpentaria. Similar processes have also been identified in the Savannah regions of the NT and WA, particularly the Victoria and Ord Rivers. It has also been suggested that broad scale gully erosion of this type and associated local (more)...

A remote sensing approach for mapping and classifying riparian gully erosion in Tropical Australia

Alluvial gully erosion has been one of the dominant contemporary sediment sources in many of the large rivers draining into the Gulf of Carpentaria, yet, fundamental questions persist concerning the phenomenon both in terms of causal mechanisms and extent. In this project a baseline assessment of alluvial gully erosion in four tropical savannah rivers was undertaken resulting in both the development of a gully erosion conceptual model and an assessment of the spatial extent of gully erosion.

Indicator for Site-Based Erosion Assessment Using a Mixture of Field Data and Modelling

National Monitoring and Evaluation Framework

 This document reports on the Wind Erosion Assessment Model (WEAM) for field-based wind erosion risk assessment. The objective was to assess if WEAM could be used by regional Natural Resource Management (NRM) bodies to assess erosion levels of different land management practices on different (more)...

Dynamics of sediment and nutrient fluxes from burnt forest catchments

Final Report for Land and Water Australia Project DSE1, and Victorian Department of Sustainability and Environment Project

The magnitude of the impact of wildfire on water quality in SE Australia has rarely been estimated because the location and timing of wildfires is unpredictable, usually precluding the establishment of robust before and after impact experimental designs.  However the 2003 Alpine fires presented a rare opportunity to overcome this constraint when two long-term water quality research catchments were burnt by wildfire. The combination of a sound experimental design and (more)...

LANDSCAN: Managing Landscapes - matching soils, climate and enterprises

Acidity, salinity, nutrient deline, erosion have major production and environmental impacts in NSW. An estimated 16-20m hectares in the state are affected to water erosion and 200,000 hectares are affected by salinity.

Land Water and Wool Case Study: Brendan Lunney, Yass

Wool producer shores up land to shore up profits

Brendon Lunney remembers reading as a schoolboy about how water was washing away Australia’s farmland. He grew up, studied arts and seemed bound for other things when, at the age of 27, he bought a farm. Now, three decades later, the reality of his early school learning and the devastation wrought by water washing through eroding gullies have become all too apparent. Measurements logged by scientists funded by the Land, Water and Wool program on his farm “Bogolara”, near (more)...

Condamine Catchment Water Erosion Monitoring

This document reports on an assessment of those recommendations applied at catchment scale and provides information on procedures that others may follow and improve upon. Tasks involved were: Comparing methods for estimating groundcover Report on use of land management practices for water erosion control - Undertake air photograph interpretation and ground observations of gully erosion - Report on use of land management practices for gully (more)...

Daly Douglas Water Erosion Monitoring

This trial was to look at methods to determine the presence and extent of erosion and level of erosion risk in the context of monitoring. Evidence may be gathered from remote sensing and field measurements.   Temporal data from ground-based monitoring sites builds up a body of knowledge on local landscape processes. By relating time-series satellite data to temporal on-ground measurements, insight is gained into the response of systems in various conditions. Based on these (more)...

Indicator guidelines: sedimentation/erosion rates

Estuarine, coastal and marine habitat condition

This document presents the recommended monitoring guidelines for collecting, collating and reporting information on sedimentation/erosion rates for national, state/territory and regional application.

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)...
