The current Flood Study considers land use changes subsequent to previous modelling investigations, the influence of the Narrabeen Lagoon entrance on flood behaviour and the influence of potential climate change. \r\n\r\nThe primary objective of this Flood Study is to define the flood behaviour under historical, existing and future conditions (incorporating potential impacts of climate change) in the Narrabeen Lagoon catchment for a full range of design flood events. The study provides information on flood levels and depths, velocities, flows, hydraulic categories and provisional hazard categories. The Flood Study has also identified the impact on flood behaviour as a result of future climate change and potential changes in the catchment and lagoon entrance. Specifically, the study incorporates: \r\n\r\n* Compilation and review of existing information pertinent to the study and acquisition of additional data including survey as required; \r\n* Undertaking of a community consultation and participation program to identify local flooding concerns, collect information on historical flood behaviour and engage the community in the on-going floodplain management process; \r\n* Development and calibration of appropriate hydrological and hydraulic models; \r\n* Determination of design flood conditions for a range of design events including the Probable Maximum Flood (PMF), 0.1%, 0.2%, 0.5%, 1%, 2%, 5%, 10%, 20% and 50% AEP events for catchment derived flooding and the 0.5%, 1%, 2%, 5%, 10% and 20% AEP events for ocean derived flooding; and \r\n* Assessment of potential impact of climate change using the latest guidelines. \r\n", "num_resources": 1, "num_tags": 4, "organization": {"id": "bc8b9274-7fc7-4576-8211-9fd11d7f42e5", "name": "northern-beaches-council", "title": "Northern Beaches Council", "type": "organization", "description": "The Northern Beaches Council is a recent LGA on Sydney's northern beaches formed from the merger of Manly, Pittwater and Warringah councils. \r\n\r\nhttp://www.northernbeaches.nsw.gov.au/\r\n\r\nFlood Studies, Plans and Maps available:\r\nhttp://www.pittwater.nsw.gov.au/property/natural_hazards/flooding/where_does_it_flood/flood_studies_and_plans\r\n\r\nCareel Creek\r\nAvalon to Palm Beach Flood Risk Management Study and Plan - current project.\r\nCareel Creek Catchment Flood Study - July 2013\r\nCareel Creek Floodplain Risk Management Plan November 2002 \r\nCareel Creek Floodplain Management Study Sept 2000 \r\nCareel Creek Drainage Catchment Flood Study June 1999 - superseded\r\n\r\nGreat Mackerel Beach\r\nGreat Mackerel Beach Floodplain Risk Management Study and Plan - November 2010\r\nGreat Mackerel Beach Flood Study September 2005\r\n\r\nMona Vale/Bayview\r\nMcCarrs Creek, Mona Vale and Bayview Flood Study - current project\r\nMona Vale - Bayview Flood Study May 2002\r\n\r\nNarrabeen Lagoon\r\nNarrabeen Lagoon Flood Study - September 2013\r\nNarrabeen Lagoon Floodplain Risk Management Plan Vol 1 Pittwater December 2002\r\nNarrabeen Lagoon Floodplain Management Study 1992\r\n\r\nNareen Creek (subcatchment of Narrabeen Lagoon)\r\nNareen Creek Flood Study September 2005 - superseded\r\n\r\nWarriewood Valley (subcatchment of Narrabeen Lagoon)\r\nWarriewood Valley Flood Study April 2005 - superseded\r\nWarriewood Valley Flood Study Addendum 1 July 2005 - superseded\r\nWarriewood Valley Urban Land Release Water Management  Specification - February 2001\r\n\r\nNewport\r\nNewport Beach Floodplain Risk Management Study & Plan February 2004\r\nNewport Beach Flood Study March 2002\r\n\r\nOther Areas\r\nPittwater Overland Flow Mapping and Flood Study - October 2013\r\nMcCarrs Creek, Mona Vale and Bayview Flood Study - current project\r\nAvalon to Palm Beach Flood Risk Management Study and Plan - current project\r\n", "image_url": "2021-03-23-012619.270871northern-beaches.png", "created": "2021-02-17T08:04:20.227446", "is_organization": true, "approval_status": "approved", "state": "active"}, "owner_org": "bc8b9274-7fc7-4576-8211-9fd11d7f42e5", "private": false, "spatial": "{\r\n \"type\": \"Polygon\",\r\n \"coordinates\": [\r\n  [\r\n   [\r\n    151.17324829101562,\r\n    -33.768302760939015\r\n   ],\r\n   [\r\n    151.17324829101562,\r\n    -33.648350342817636\r\n   ],\r\n   [\r\n    151.34559631347656,\r\n    -33.648350342817636\r\n   ],\r\n   [\r\n    151.34559631347656,\r\n    -33.768302760939015\r\n   ],\r\n   [\r\n    151.17324829101562,\r\n    -33.768302760939015\r\n   ]\r\n  ]\r\n ]\r\n}", "spatial_coverage": "New South Wales (NSW81093)", "state": "active", "temporal_coverage_to": "2013-09-25", "title": "Narrabeen Lagoon Flood Study Report", "type": "dataset", "unpublished": "false", "update_freq": "as_required", "url": null, "version": null, "extras": [{"key": "fdp_type", "value": "related-dataset"}, {"key": "harvest_portal", "value": "Flood Data Portal"}, {"key": "harvest_url", "value": "https://flooddata.ses.nsw.gov.au/related-dataset/narrabeen-lagoon-flood-study-report-2013"}], "groups": [{"description": "The function of [land and resource management](http://search.records.nsw.gov.au/functions/10) includes the administration of crown land and the process of alienation, including surveying, mapping, and the preparation of leases and titles.
