 "description": "The Department of Water and Environmental Regulation produces floodplain mapping of rivers and major watercourses and provides floodplain development advice to ensure that proposed floodplain development has adequate flood protection and does not impact on the existing flood regime of the area.\n\nThis advice is related to major river flooding only. Other issues, such as stormwater drainage and envirionmental and ecological considerations are not addressed. \n\nThis dataset contains the location of cross sections lines, indicating modelled / surveyed cross sections of the river channel and floodplain. \n\nThe cross sections are labelled using chainage, which is generally defined as the distance from the DWERnstream start of a flood study traversing up the river. The cross sections are defined perpindicular to the flow direction and illustrate how the relevant flood levels are to be applied across the floodplain. \n\nEach cross section has an associated flood level listed in the attribute fields as follows:\n\nFLDLVL_10 (1 in 10 (10%) AEP flood event)\n\nFLDLVL_20 (1 in 20 (5%) AEP flood event)\n\nFLDLVL_25 (1 in 25 (4%) AEP flood event)\n\nFLDLVL_50 (1 in 50 (2%) AEP flood event)\n\nFLDLVL_100 (1 in 100 (1%) AEP flood event)\n\nFLDLVL_DFE (Designated flood event)\n\nFLDLVL_200 (1 in 200 (0.5%) AEP flood event)\n\nFLDLVL_500 (1 in 500 (0.2%) AEP flood event) \n\nFLDLVL_MCC (Maximum channel capacity)\n\nFLDLVL_PMF (Probable maximum flood event)\n\nNote: To see the full scope of the floodplain mapping, 12 dataset layers are required to be loaded in the following order:\n\nFLOODPLAIN DATASET LAYERS: \n\nFPM Flood Level Points (m AHD)\n\nFPM Flood Level Contours (m AHD)\n\nFPM 1 in 100 (1%) AEP Floodway and Flood Fringe Line\n\nFPM Extent of Flooding\n\nFPM Levee Banks\n\nFPM Location of Cross Sections\n\nFPM 1 in 100 (1%) AEP Floodplain Development Control Area\n\nFPM Map Index\n\nFPM Bridges\n\nFPM Special Development Condition Area\n\nFPM 1 in 100 (1%) AEP Floodway and Flood Fringe Area\n\nFPM Floodplain Area\n\nLicense: Creative Commons Non-Commmercial (Any)\n\nTags: DWER, Flood, Hazards, Water\n\nContact: gerard.paul@dwer.wa.gov.au",
