The Without Development Model is a hydrological model of a river system without any representation of water infrastructure (e.g. storages, weirs), water extraction, water management and operating rules in the system. It includes runoff for headwater catchments, local runoff of residual catchments, flow routing along river reaches, and transmissions losses. The Without development model is derived from the full model of the system, which is calibrated using observed data. Note: Source software (available from ewater.org.au) is required to view and run the model(s) within.

A without development model scenario is created by starting with a current conditions model scenario and switching off as much development in the model as possible. Typically this means removing all water users such as irrigation and towns along with infrastructure such as dams and weirs. A without development scenario is useful in understanding the extent to which human uses of the river have altered flows. This type of model scenario is sometimes known and a “natural case” but this terminology has fallen out of favour over time as a true natural condition scenario would attempt to reflect catchment conditions such as land use, vegetation cover and so on that existed prior to human interventions.

The Macquarie Without Development model covers the headwater catchments and river reaches of the Macquarie River basin. This includes the Macquarie River and explicit representation of its major tributaries such as the Fish River, Cudgegong River, Bell River, and Talbragar River, amongst others. It also covers the headwater catchments and river reaches of the Bogan River, and various floodplain distributaries and anabranches in the lower reaches of the Macquarie River basin. The model extends downstream to locations upstream of the Barwon River. The model extent does not include the Castlereagh River. Note: Source software (available from ewater.org.au) is required to view and run the model(s) within.

To construct a high-level evaluation scenario for the Water Sharing Plan (the Plan) for the Macquarie and Cudgegong Regulated River Water Source all account-based Plan Environmental Water (PEW) rules and Held Environmental Water (HEW) licences have been removed from the Current Conditions model. Specifically, it included the following PEW rules stipulated in Section 14 of the Plan: Environmental Water Allowance for Cudgegong The Macquarie Translucent sub-allowance Macquarie Active sub allowance The flow at the following key sites within the river system has been considered in the evaluation analysis (with data provided for an extended range of sites): 1) 421019_Cudgegong@YambleBridge 2) 421001_Macquarie@Dubbo 3) 421004_Macquarie@WarrenWeir 4) 421012_Macquarie@Carinda 5) Combination of 421088_MareboneBreak and 421090_Macquarie@DSMareboneWeir 6) 421146_Gum Cowal @ B/Cation 7) 421022_Macquarie@OxleyStation 8) 421090_Macquarie@DSMareboneWeir Note: If you would like to ask a question, make any suggestions, or tell us how you are using this dataset, please visit the NSW Water Hub which has an online forum you can join.
