Freight transport following an extreme rainfall event

Abstract

The Cairns region of North Queensland is subject to tropical cyclones and the associated torrential rains which may accompany such events. The result of this torrential rain is that the transport links into and out of Cairns are frequently closed preventing the movement of freight along normal routes. This report has been undertaken with two main focuses: Firstly this report has reviewed rainfall data to determine what, if any, impact the greenhouse effect will have, and secondly this report has identified and reviewed freight management plans for both emergency and general freight. The results of the investigation into the greenhouse effect have determined that there is expected to be an increase in extreme precipitation and flooding if steps are not taken to address the greenhouse effect. For the study area of Cairns, it is estimated that this increase in rainfall will equate to approximately 4mm/day in 2026 The results of the investigation into the current planning has determined that while there is adequate high level planning, particularly for counter disaster situations (i.e cyclones), there is a no planning at the low level developed by freight operators who have the responsibility to manage their own freight. As such this report has developed a list of objectives and recommendations to assist with the development of freight plans. In addition to these objectives and recommendations, this report has presented a wealth of information on transport links within the Cairns area covering the threats imposed by extreme rainfall events. It should be noted that the key to the successful development of any freight plans, is the consultation process which requires advice from many different professionals.
