The information and results obtained from the study will provide a firm basis for the development of targeted stormwater management studies, and a subsequent Floodplain Risk Management Study and Plan.\n\nThe study was developed in order to meet the primary objective of defining the flood behaviour (2, 5, 10, 20, 100 and 200 year ARI design storms and the Probable Maximum Flood) in the Cooks River and Coxs Creek catchment and to: define flood behavior in terms of flood levels, depths, velocities, flows and flood extents within the Cooks River and Coxs Creek catchment study area, prepare flood hazard and flood extent mapping, prepare suitable models of the catchment and floodplain for use in a subsequent Floodplain Risk Management Study. to assess the adequacy and capacity of Council's existing pipe network and quantify\noverland flows, to consider the potential effects of a climate change induced increase in design rainfall intensities.\n\nThis report details the results and findings of the Flood Study investigations. The key elements include: \n<ul>\n<li>description of study area, </li>\n<li>results of distribution of questionnaires (Figure 5), </li>\n<li>a summary of available historical flood related data, </li>\n<li>calibration of the hydrologic and hydraulic models, </li>\n<li>definition of the design flood behaviour for existing conditions through the analysis and interpretation of model results sensitivity analysis and the assessment of the effects of a climate change induced increase in design rainfall intensities.</li>\n</ul>\n\nA glossary of flood related terms is provided in Appendix A.\n\nThe Study Area\n\nThe Cooks River and Coxs Creek have a combined\ncatchment area of approximately 22km2 contributing\nup to Punchbowl road. The contributing catchment\nincludes some areas from the suburbs of Strathfield\nSouth, Enfield, Enfield South, Rookwood, Belfield,\nChullora, Potts Hill, Bankstown North, Greenacre,\nPunchbowl, Mt Lewis, Wiley Park, Roselands, and\nBelmore.\n\n<strong>Outcomes:</strong> The main outcomes of this study are: \n* full documentation of the methodology and results, \n* preparation of flood contour, depth, velocity, hazard and extent maps for the study area, \n* a modelling platform that will form the basis for a subsequent Floodplain Risk Management Study and Plan.\n\n<strong>Recommendations:</strong> This Flood Study should be adopted by Council before proceeding with the subsequent floodplain risk management Study and Plan. As part of these subsequent studies a risk analysis of the implications of climate change on flooding should be undertaken.\n\nThe key recommendation from this study is to highlight the importance of collecting and maintaining a database of historical rainfall and flood height data. It is vital that information from future flood events is collected within 24 hours and the magnitude and direction of flow paths through private property recorded. This information will significantly improve the accuracy of the design flood levels and extents and ensure that known flood areas are identified and assessed. Data collection can be undertaken by Council Officers digitally photographing flood marks etc. (they can be levelled later based on the photograph) and possibly mailing out a resident questionnaire requesting information and photographs. Unfortunately if this process is not done quickly, information is lost forever.\n\nStormwater within this section is carried within the\nunderground piped network and open channel\nsystem, or when this is exceeded, along roads or\nthrough private property.", "num_resources": 1, "num_tags": 5, "organization": {"id": "f4c253cb-6ba8-4405-b2ae-f3167ee4ad4a", "name": "strathfield-municipal-council-datansw", "title": "Strathfield Municipal Council", "type": "organization", "description": "The Local Government Area of Strathfield has a total area of approximately 14.1 square kilometres and home to over 40,000 people.
