Central to this was the\ndevelopment of a two-dimensional hydraulic model of the floodplain.\nIn completing the flood study, the following activities were undertaken:\n\u2022 Collation of database of historical flood information for the Clarence Town catchment;\n\u2022 Acquisition of topographical data for the catchment including cross section and hydraulic\nstructure survey;\n\u2022 Consultation with the community to acquire historical flood information and liaison in regard to\nflooding concerns/perceptions and future floodplain management activities;\n\u2022 Development of a hydraulic model (using TUFLOW software) to simulate flood behaviour in the\ncatchment;\n\u2022 Calibration of the developed models using the June 2007, February 2009 and February 2011\nflood events;\n\u2022 Prediction of design flood conditions in the catchment using the calibrated models; and\n\u2022 Production of design flood mapping series.\nA good model calibration and validation was achieved with the available data, confirming the\nappropriateness of the model for design flood simulation.\nThe local catchment flooding is typically characterised by a series of well-defined overland flow paths\nthat feed the main Town Creek channel prior to discharge to the Williams River. Given the relatively\nsmall size of the contributing catchments, extensive flood inundation of property is somewhat limited.\nOnly three existing properties (all commercial premises) have been identified as at potential risk of\nabove floor flooding for events up to the 1% AEP flood magnitude.\nThe majority of the natural flood flow paths are through private land. In most part, development on\nthese lots has been located a sufficient distance from the natural drainage lines to limit potential for\nbuilding inundation.\nThe lower reaches of the Town Creek catchment are dominated by Williams River flooding. Typically\ndownstream of approximately the IGA culvert, the Williams River 1% AEP design flood results in\nhigher flood conditions than corresponding 1% AEP local catchment event. Accordingly, the Williams\nRiver design flood conditions established by BMT WBM (2009) should be applied for future flood\nplanning and development control in these lower reaches.", "num_resources": 1, "num_tags": 1, "organization": {"id": "14c0b013-1eb5-4c3f-8624-f46bce1aaae6", "name": "dungog-shire-council-datansw", "title": "Dungog Shire Council", "type": "organization", "description": "__The Shire of Dungog__ is part of the Hunter Region and the Lower Hunter Sub-Region and is bound by Great Lakes Shire to the East, Singleton Shire to the West, Scone Shire to the North-west, Gloucester Shire to the North and by Port Stephens Shire and the City of Maitland to the South.\r\n\r\n__Geography__\r\n\r\nDungog Shire covers an area of 2248 sq Kilometres. The Council is situated in the Barrington tops region and has a population of 8,500. The Shire consists predominantly of very rugged to hilly country which becomes less rugged from north to south. The major population centres within the Shire include:\r\n\u2022Dungog\r\n\u2022Gresford\r\n\u2022Paterson\r\n\u2022Vacy\r\n\u2022Martins Creek\r\n\u2022Clarence Town\r\n\r\n__Rivers__\r\n\r\nThe Shire has two principal rivers, the Williams in the east of the Shire and the Paterson in the west. Both are tributaries of the Hunter, and both traverse the Shire in a general north-west to south-east direction. The Williams and Paterson Rivers drain from the Barrington Plateau and contribute over 40% of the flow of the Hunter. Lostock Dam was constructed on the Paterson River in the 1970's to regulate flow and prevent lack of water in drought.\r\n\r\nhttp://www.dungog.nsw.gov.au/about-shire", "image_url": "", "created": "2025-06-24T03:40:09.302246", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://data.nsw.gov.au/data/", "href": "https://data.nsw.gov.au/data/dataset/nsw-fdp-clarence-town-flood-study-inc-appendix-and-figures", "title": "DataNSW"}, "original_name": "nsw-fdp-clarence-town-flood-study-inc-appendix-and-figures", "owner_org": "14c0b013-1eb5-4c3f-8624-f46bce1aaae6", "private": false, "promotion_level": "0", "remote_last_updated": "2026-01-13 03:41:45.375748", "spatial": "{\"type\": \"Point\",\"coordinates\": [147.0179,-32.1618]}", "spatial_coverage": "New South Wales (NSW81093)", "state": "active", "temporal_coverage_from": "2025-12-17 05:36:48.896671", "temporal_coverage_to": "2012-03-01 00:00:00", "title": "Clarence Town - Flood Study Inc Appendix and Figures", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "f34e121e-732f-4828-86d4-cc1b8bad973a"}, {"key": "harvest_source_id", "value": "9ebac586-8e51-4904-9f6c-d9b79726659a"}, {"key": "harvest_source_title", "value": "DataNSW"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2026-01-13T03:41:45.402153", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "format": "HTML", "hash": "", "id": "35cafd3f-0a0f-4419-922b-0c9aa011ca23", "last_modified": null, "metadata_modified": "2026-01-21T18:06:16.427980", "mimetype": null, "mimetype_inner": null, "name": "Clarence Town Flood Study", "package_id": "796515ac-5ac1-407e-8022-481824a3dec9", "position": 0, "resource_type": null, "size": null, "state": "active", "url": "https://flooddata.ses.nsw.gov.au/dataset/07a15995-04a6-47fa-9486-79be7af3441c/resource/d061ec14-5e69-4476-9541-5f466246785e", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "Clarence Town", "id": "0d32853d-eff3-4434-85d1-ddace4398f93", "name": "Clarence Town", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
