on the floodplain, these projects are intended to deliver environmental outcomes to provide a greater extent of watering than the benchmark conditions, watering up to 350 ha for the Vinifera floodplain (55% of the total area, Figure 12), 500 ha for the Nyah floodplain (53% of the total area, Figure 13), and 407 ha for the Burra floodplain (33% of the total area, Figure 14). Proponent Victoria Resource units affected by the measure All surface water resource units in the southern Basin Representation of the project in the MDBA modelling framework In preparing the business cases for these projects, Victoria has developed various supporting materials including hydrodynamic models to assist designs of the proposed structures and their operating regimes. Based on the information provided by Victoria, MDBA has updated the Murray model and incorporated hydrologic characteristics of the project sites including intended operations of the works. Key model data that is agreed and endorsed is presented below. Figure : Overview of proposed works and inundation extent of the Vinifera Creek project Figure : Overview of proposed works and inundation extent of the Nyah Creek project Figure : Overview of proposed works and inundation extent of the Burra Creek project The Murray model represents the three works sites with one wetland and a branch flow per site to describe hydrological characteristics and operations of the proposed works (Figure 15). Figure : Representation of the Vinifera, Nyah and Burra Floodplains in the Murray model Key information used to model the sites is presented at Table 14 and Table 15. There are three modes of operations for each project as described at Table 14.
