It ~as strong suppor~ from the project team. 3rochures are ~ot usually 2een as effective vehicles for public information, but the cecall level of over 50% is probably slightly better than 3verage for this type of program. The useful map of Alice Springs probably helped e~sure that people retained the brochure for longer tha~ would otherwise have been the case. Warning and emergency management 'I'~ose flooded did not receive official warnings. ~owever, it ~s impo~~a~t that apparent de:iciencies in the Al:ce Springs flood warning and emergency response system are placed within a ~atio~al context. Floodwarnings are not well developed within Australia. One major factor has been IJncertainty as to which level of gove=~menc has lead resp0:1sibl:'ity, federal, state or local (Smith and Handmer, 1986). Fo:: example, the serious flooding in Sydney during August 1986, highlighted many deficiencies. Warnings for flooding from the Georges River were based on information from five manually read rain gauges, only two of which managed to reporc to the Bureau of Meceorology, the responsible authori~y. Warning ~essage disseminatio~ was 3150 poor. Many thousa~ds are a~ ~isk and an extreme flood would be devastating as it would be many metres higher than ~he 1986 event. In addition, no formal ~lood warning system whatsoever exists :or ~ost u~banised catch8ents. Thus, Alice springs with a flood detection syste~, .a data base of property at risk, and a brochure detailing the flood proble~, was considerably more prepared than many ?ustralian comrnunities. :-io',.;ever, as always improveme~ts can be made to this basic framework. Recommendations Tangible damages ~ Tanaible losses to motels/hotels were particularly large. This group Dight bene=it substantially f~om individual advice on flood damaae reduction and from advance warnlng: these ~nclude the Outback Motor ~odge, Lasseters Casino, the Pacific Resort Hotel and Oasis Resort Hotel. Measures to flood proof t~e hospital should be given ~igh priori~y. - Small i:1creases in flood level above that of 1988 would inundate a very large numbe:: of additicnal properties and result in substanti~llv i~creased tangible damages. :his ~as serio~s implicat~o;s for safety and should be considered in emergency planning and in the development of floodplai~ management.
