“…These natural disasters have significant impacts on individual and safety. Hobbs and Lawson (1982) presented that Gold Coast suffered a series of serious tropical cyclones, damages estimating at AU$360 million in 1967. According to Bureau of Meteorology, Cyclone Larry was first tracked on 16 March 2006 which was classified as Category 5 with winds over 260 km/h on the northern coast of Queensland (BOM, 2006).…”

A number of geographical areas within Australia are subject to frequent and significant natural disasters such as cyclones and flooding. Such events impact individuals and businesses directly and indirectly through the disruption of the routine movement of goods, services and people. The importance of identifying core challenges in the management of transport networks has been highly recognized by state and local governments. In Queensland, the responses to natural disasters involve the efforts from a number of agencies, including local city councils, local disaster management group, emergency services, police services, health/ambulance, and transport authorities, under the coordination of local disaster coordination centre. In this research, we look at the coordination and communication (C&C) among multiple agencies in response to natural disasters. Two organizational C&C mechanisms are evaluated based on the functional resonance analysis method by assuming several representative hypothetical scenarios. The applicability of the two mechanisms is also discussed accordingly.

“…However, the details of their analysis are vague and are not related to the underlying forest conditions. In other studies similar to the one we present, Hobbs and Lawson () developed an average decadal incidence of storms affecting Australia based on the geographical analysis of others. McGregor () performed an analysis of vulnerability for the South China Sea, although the data used was much coarser than what we use here and the emphasis was on determining return intervals for damaging storms rather than on the potential impacts to forests.…”

Relative vulnerability of the forests along southeastern African coasts to cyclones

The forests of southeastern Africa are vulnerable to damage imposed by tropical cyclones operating in the South Indian Ocean. We undertook a geographical analysis to determine the relative vulnerability of forests given tropical cyclones recorded during the 1959–2008 storm seasons. From this analysis, eastern coastal forests of Madagascar seem to be the most vulnerable, although return intervals for severe storms vary along the eastern coast, and are shorter (about 10 years) through the central portion of the country. Therefore, the central lowland to upper montane rainforests on the eastern coast seem to be more vulnerable to damage from tropical cyclones than others in the area. While not as extensive, western coastal forests of Madagascar are also as vulnerable in part due to the recurvature of storms in the Mozambique Channel. Though the coastal forests of Mozambique are all nearly equal in terms of vulnerability, the return interval for severe storms to this area is highly variable. The inland Miombo forests of southeast Africa are less vulnerable to damage from tropical cyclones; however, portions of western Mozambique and Zimbabwe have experienced strong tropical storms in the last 50 years. A number of caveats and limitations associated with the data and analyses are noted. Given the broad scale of the study, the relative vulnerability and the return intervals for severe storms should be considered general representations of these phenomena for the southeastern African coast and the island of Madagascar.

Erosion of the southern Gold Coast beaches (SE Queensland, Australia) was exacerbated after the extension of the Tweed River training walls in the early 1960s. To achieve the objective of restoring and maintaining beach amenity, significant nourishment works have been undertaken in Coolangatta Bay over the past 30 years. Particularly, under the Tweed River Entrance Sand Bypassing Project (TRESBP) since 1995, a number of nourishment campaigns and the implementation of a permanent sand bypass system in 2001 have resulted in significant changes of Coolangatta Bay morphology. The present case study investigates the influence of both wave climate and nourishment works on the area extending from the updrift Snapper Rocks area to downdrift Kirra Beach. SWAN spectral wave model is implemented at Coolangatta Bay area and forced by the global wave model WW3 to estimate wave forcing and the potential natural longshore drift entering in Coolangatta. Specific transects extracted from accurate bathymetric surveys are used to investigate and quantify Coolangatta Bay sedimentation for the period 1987-2005. A network of Argus video stations provides high sample rate information on the shoreline evolution. Results show that, over the past 10 years, Coolangatta Bay has infilled rapidly. Sedimentation reached up to 6 m in some areas between 1995 and 2005, with beach width increasing by 200 m at Kirra Beach. Rapid seaward shoreline migration is consistent with the intense over-pumping of sand relative to the natural potential to move sand alongshore. The nourishment strategy used during this project has successfully delivered large amounts of sand to the southern Gold Coast embayment, although it has been up to now controversial from many community perspectives. The artificial sand bypassing process proved to be much more efficient than depositing the dredged sand in the nearshore area which requires a significant period of low energy condition in order for the deposited sediment to migrate shoreward and weld to the shore. This case study confirms that, when carefully undertaken, sand bypassing is a sustainable and flexible soft engineering approach which can work in concert with natural processes.
