It is an urban catchment\nthat drains through a stormwater pipe network and Freshwater Creek in a north-easterly direction to\nthe Cooks River. The catchment is bounded by the Hume Highway to the south and east, and the\nrailway line to the north. The Rookwood Road catchment is wholly within the Bankstown City local\ngovernment area (LGA).\n\nOutcomes from the Study\n\nThe main outcomes from this study include:\n<ul>\n<li>A database of all Council drainage assets within the study area;</li>\n<li>Establishment of a computer model capable of assessing flood behaviour;</li>\n<li>Information on flood behaviour under existing catchment conditions;</li>\n<li>Predicted change in flood levels due to the potential impacts of climate change; and</li>\n<li>A model that can be used to assess flood mitigation options and future development proposals.</li>\n</ul>\n\nDatabase of Drainage Assets\n\nAll drainage asset data collected by Council for the study has been incorporated into a GIS database.\n\nThis allows the data to be spatially represented across the study area and easily retrieved as\nrequired. Information in the database includes data for some 550 stormwater pits and 680 stormwater\ndrainage pipes.\n\nOther catchment data, including aerial photography, property cadastre, building footprints and the\nterrain surface (based on ALS survey) is also incorporated into a GIS database.\n\nComputer Modelling\n\nA numerical computer model was developed for the catchment to simulate flood behaviour, using the\nsoftware TUFLOW. Surface flows are represented in the model through a two-dimensional grid\ncovering the entire study area. The stormwater pit and pipe network is included as one-dimensional\nelements within this grid. Full details of the modelling approach, modelling parameters and other\nassumptions are outlined in the Rookwood Road Catchment Flood Modelling Report, which is\nincluded as Appendix C.\n\nExisting Flood Behaviour\n\nDesign flood behaviour has been computed for a range of floods, ranging from relatively frequent\nevents to more extreme floods.\n\nThe model produces a grid of results over the study area providing data on flood levels, flood depths\nand flood velocities. Flood level contours have also been prepared showing contours of flood heights\nthroughout the study area. This data is provided digitally and can be overlaid on base mapping such\nas aerial photos and cadastral plans showing property boundaries.\n\nAll flood model results have been provided to Council for incorporation into their GIS database. Much\nof this information is also included as A4 sized plans included in Appendix C.\nIt is understood that once the Flood Study has been adopted by Council, the GIS information\nresulting from this Flood Study will be used for floodplain management purposes, including\nassessment of flood-related development constraints on properties. Potential flood mitigation options\nwill be assessed in the subsequent Floodplain Risk Management Study phase of the floodplain risk\nmanagement process.", "num_resources": 1, "num_tags": 4, "organization": {"id": "87dd8c0c-af2f-40df-b356-9efc8ea0f5f4", "name": "canterbury-bankstown-council-datansw", "title": "Canterbury-Bankstown Council", "type": "organization", "description": "A\u202fnew City of Canterbury Bankstown\u202fwas announced by the NSW Government on\u202f12 May 2016.\u202f The City of Canterbury Bankstown replaces the Bankstown and Canterbury Councils, and becomes the largest Council in NSW with 350,000 residents, and is in Sydney's south west.\r\n\r\nhttps://www.cbcity.nsw.gov.au/\r\n\r\nCouncil has a chapter in the Development Control Plan (DCP) - Part B12 - which deals specifically with Flood Risk Management in the Local Government Area.
