<p>Development of floodplains in the western rural areas of NSW is managed through Part 8 of the Water Act 1912. Part 8 was gazetted in 1984 and makes provisions concerning 'flood control works' that affect, or are likely to affect, flooding or floodplain functions. Part 8 was amended in 1999 to allow for more strategic control of flood control works through the preparation of rural Floodplain Management Plans (FMPs) and a more streamlined and resource efficient approval process. The amendments also required that rural FMPs be developed in accordance with the provisions and policies of the operative NSW Manual (currently, Floodplain Development Manual, NSW Government, 2005). <p>The manual supports the primary objective of the New South Wales Government's Flood Prone Land Policy to reduce the impact of flooding and flood liability on individual owners and occupiers of flood prone property, and to reduce private and public losses resulting from floods, utilising ecologically positive methods wherever possible. The formulation and implementation of FMPs is the cornerstone of the policy and the process for their preparation is described in the manual. <p>Administrative orders published in April 2007, inter alia, divided the responsibilities under Part 8 of the Water Act 1912 between the Department of Environment and Climate Change (preparing rural FMPs) and the Department of Water and Energy (implementing the plans through licensing and compliance functions). <p>On 1 July 2009, following a Reorganisation of Government Agencies, the licensing and compliance functions regarding Part 8 were transferred to the newly established Office of Water within the renamed Department of Environment, Climate Change and Water (DECCW). Please note that any reference in this document to the Department of Environment and Climate Change, and Department of Water and Energy, is to be construed as a reference to DECCW. <p>The development of a rural FMP progresses through three (3) key stages: Data Collection & Flood Study (FS) - in general, includes data collection for hydrology, hydraulic and environmental aspects; defines the nature and extent of flooding, including development of a computer-based hydraulic model of flood behaviour; Floodplain Risk Management Study (FRMS)- in general evaluates management options based on hydraulic modelling, analysis of the floodplain environment and social and economic considerations, to address existing and future floodplain risk management issues; and Floodplain Management Plan (FMP) - presents the recommended management measures for the floodplain, as determined in the Floodplain Risk Management Study, and includes an implementation program with priorities. <p>This current project, overseen by the Darling River Floodplain (Bogan River confluence to Louth) Floodplain Management Committee (the Committee) and prepared for DECCW, includes only the first of the above three elements of the Floodplain Management Plan process, and is structured as follows: <p>Stage 1: Data Compendium and Digital Terrain Model <p>All information and knowledge of the flood regime in the study area are included in a Compendium of Data (COD), as a permanent record, and for later use in Stage 2 of the FS. <p>A Digital Terrain Model was prepared for hydraulic modelling use in Stage 2 of the FS and the results presented on an appropriate Geographic Information System (GIS). <p>Stage 2: Calibrated Hydraulic Model and Final Flood Study Report <p>A calibrated computer based hydraulic model was developed to quantify the distribution of floodwaters during historical flood events and for later use in designing a floodway network (as part of the FRMS) in order to evaluate management options. <p>The Compendium of Data was completed in July 2008. This Report covers Stage 2: Calibrated Hydraulic Model and Final Flood Study Report. <p>The Commonwealth Government's Natural Disaster Mitigation Program (NDMP) and the New South Wales State Government through the NSW State Emergency Management Committee (SEMC) have jointly provided funding for the project.

Background This report describes a project which involved the capture and processing of LiDAR and coincident imagery and resultant derived products for the lower reaches of the Darling River. The data joins two existing LiDAR datasets, one to the north covering the Menindee Lakes and the other in the south along the Murray River corridor. It is intended to provide the Murray-Darling Basin Authority with a very accurate, quality assured measurement of topography in order to accurately model the flow and volume of water in the floodplains within the project area. The LiDAR was captured in April and May 2013 at a point density of two 1st return points per square metre within swath, (equivalent to two outgoing laser pulses per square metre at ground level). The specified accuracies; 30cm vertical and 80cm horizontal, were achieved and verified through a rigorous network of ground check points and base stations. A set of seamless products were produced including hydro-flattened bare earth DEMs, DSMs and cartographic contours. The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF.

AAM Pty Ltd was commissioned by NSW Government's Office of Environment & Heritage to conducted an airborne LiDAR and Imagery survey over sections of the Gwydir Valley Floodplain west of Moree in north west NSW to assist with the development of Valley Wide Floodplain Management Plains under the Healthy Floodplain program. There has already been some LiDAR acquisition and this data will supplement this information. Collection of both LiDAR and simultaneous imagery utilizing the Optech ALTM Pegasus LiDAR sensor and DiMAC Ultralight medium format digital camera occurred from 31 May 2013 until 19 June 2013 (total of 7 separate flights). The primary use of the LIDAR data will be to provide topographical information necessary to define flood behaviour and undertake hydraulic modeling of floods in the area. Data is to be provided to LPI Classification 3 This project report provides specific information on: Project Details; Project Plan; Pre-Survey Quality Assurance Plan; Post-Survey Spatial Accuracy Report; Unforeseen/Extra-ordinary circumstances faced; Project Deliverable details; Statement of compliance; Control Reporting; Metadata documentation; Further project requirements.

The data covers an area of approximately 4600 sq km in the Namoi Valley, located around Narrabri, NSW. The LiDAR was captured in September and October 2013 with a point density of two points per square metre. The specified accuracies; 30cm vertical and 80cm horizontal, were achieved and verified through a rigorous network of check points and base stations. A set of seamless products were produced including hydro-flattened bare earth DEMs, DSMs, Canopy Height Models (CHM) and Foliage Cover Models (FCM). The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF. The survey was conducted over two areas along the Namoi River: one from Boggabri to Narrabri, and the other between Wee Waa and Walgett including a newer extension to this original area to the north east of Wee Waa.

The Edward River LiDAR survey provides elevation and photographic data over a 1200 km² along the Edward River, north of Swan Hill. The LiDAR was captured in November and December 2013, at a nominal density of two outgoing laser pulses per square metre. Photography was captured simultaneously and provided as an ortho-rectified mosaic with a resolution of 20cm. The LiDAR was delivered in a full waveform format that retains a higher level of precision and significantly more above ground information than traditional LiDAR. A set of seamless products, including hydro-flattened bare earth terrain surfaces (DEMs), were produced to the ICSM specification. Other derived surfaces include a Digital Surface Model (DSM), Canopy Height Model (CHM) and Foliage Canopy Model (FCM). The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF.
