Emergency management of flood situations in both urban and rural areas is directly concerned about the safety of people and vehicles in floods. Over the past two decades there has been increasing concern about these safety issues and there is a need to revisit and update the criteria currently used. The current approach is based on the results of some studies undertaken in the 1970s. A body of research has been undertaken since then and there is a need to collate this research and to develop guidelines for authorities. As a result, it is anticipated that most of the work involved in this project will be the collation of research in this field and the development of appropriate guideline information.
