THE IMPACT OF FLOODING ON THE DESIGN OF THE VICTORIA HIGHWAY

This paper outlines the methodology adopted for assessing the impact of flooding problems on a highway design in a remote area of the Northern Territory. Primarily it is noted that the impact is substantial. Two different techniques have been adopted in the hydrologic assessment. Peak river flows have been determined by statistical analysis of stream gauge recordings while design discharge hydrographs for local streams have been derived through rainfall- runoff modelling. Each technique is suited to the conditions and data availability of the respective problem. The derived rainfall-runoff parameters may be useful for similar catchments in the region. The use of these flow estimates in hydraulic assessments to determine road design parameters has also required two different approaches. River levels have been determined using a mathematical backwater model along a 40 km reach of the Victoria River. Levels at stream crossings have been determined by similar techniques but the interrelationship between local and river flooding has been included. Finally, the adopted highway grade line as derived from the flooding analyses will depend on the trafficability criteria selected. In this case, design standards have been specified. Alternative standards have been noted and comparisons can be made of the various impacts of the design criteria. This information should be useful for others assessing flood immunity standards for highway design in remote areas of northern Australia. (Author/TRRL)
