Alice Springs Flood Investigation and Floodplain Mapping Study

The aim of the study is to develop a 2 dimensional flood model, which allows flood flow in a complex flood plain to be modelled, to determine the extent and severity of riverine flooding in the town of Alice Springs and the Alice Springs rural area south of Heavitree Gap. The purpose of the study is to produce floodplain maps of the Alice Springs and its rural area for land use planning and counter disaster purposes. This study is an extension of the Alice Springs Farms Area Floodplain Mapping Study (WRM, 2006), undertaken by WRM on behalf of the Department of Planning & Infrastructure in 2006 in order to develop detailed Todd River floodplain maps for the rural area south of Alice Springs. The 1:10,000 scale datasets details the extent and severity of flooding in the modeled area for the Q100, Q50, Q20 and PMF flood event, mapping the peak flood surface contours, flood and floodway extent derived from hydrological modelling using topographical mapping and hydrological flood/flow datasets. The mapping dataset is displayed over a topographic/cadastral base and provides a basis for identifying the extent and distribution of peak floodwater levels for the Alice Springs town and rural area.
