Abstract

A network of unpaved sand roads exists on Fraser Island, to provide access to the sand dunes, rainforests and lakes of the World Heritage listed natural wonderland. During rainstorm events, overland flow can occur along sand roads causing severe rilling and gullying, and removal of sand by water erosion. Substantial effort and resources are required to maintain the roads to a useable condition. Continual degradation of the sand road network by water erosion from storm events may restrict long term access to the area. Water erosion modelling methods used for agriculture soil loss studies will be directly used to analyse the factors causing sand erosion by surface runoff. The data collected from water balance test plot studies can be used to design hydraulic structures to limit surface flow water velocities below threshold values for soil erosion, and deviate the water flow to vegetated areas having higher infiltration rates. The design and frequency of the hydraulic structures across the roads is in the form of rollover crossbanks with dimensions controlled by discharge rates of overland flow, threshold water velocities for erosion, and wheel-base dimensions of vehicles traversing the roads.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
