The SAFE project will ensure all of Victoria’s groundwater is included in an appropriate planning and reporting framework and that there is consistency in the way groundwater is managed across the state. This includes developing: • Boundaries: groundwater catchment boundaries that cover all groundwater in the state instead of only part of it; • Resource Share Guidance: making resource share decisions for the State of Victoria; and • Making a change: the approach to moving from the current management framework to a new framework. This report is part of the development of guidance for making resource share decisions for the State of Victoria. The Water Act (1989) provides the overarching policy for water management in Victoria. The objective of additional guidance is to describe an approach that is consistent with the requirements of the Water Act (1989), and provides further detail on how decisions could be made. This report is part of the development of an approach to move from the current management framework to the proposed management framework. The project team recognised the importance of not just recommending changes, but outlining how this could be achieved. This provides a concrete approach to implementation of the recommendations, along with supporting information that assists in making the decision to implement. Objective of this Report The objective of the report “Baseflow Separation and Analysis” was to quantify the baseflow component of streamflow across Victoria over time using a digital recursive filter. Outputs were presented in a format that enabled an understanding of the significance of groundwater baseflow to surface water flow for each station. Report Summary Baseflow analysis using a consistent method was completed for 180 stations, representing the bulk of unregulated gauging stations in Victoria. The Lyne and Hollick digital filter was applied to daily flow volume data for each station with a constant filter parameter of 0.98 adopted. The difference between the total streamflow and the baseflow was calculated as an estimate of the surface runoff (quickflow). The daily baseflow index (BFI, calculated as the baseflow volume relative to the total streamflow) was also calculated for each time step. ii Groundwater SAFE (Secure Allocations, Future Entitlements) Baseflow Separation Analysis Documentaiton of Method Key outcomes Output data for each station includes total stream flow, baseflow, quickflow and baseflow index. This allows detailed interpretation, including: • Seasonal and annual flow duration curves of streamflow, baseflow and surface runoff for each location; • Daily variability of BFI for each month; • Assessment of trends in baseflow over time (at a subset of locations); and • Control charts to help identify deviation in baseflow from reference behaviour in a predictive manner (at a subset of locations). How this report was used This information will help to improve the understanding of the volume and timing of groundwater contributions to stream flows and will form an important dataset for use in the development of groundwater entitlement volumes. It also represents the establishment of a method by which future studies may be undertaken. Figure 1 illustrates how this report fits into the overall SAFE project.

Introduction DSE is currently undertaking the SAFE project to reform Victoria’s groundwater management framework. The SAFE project will redefine groundwater management units, establish management guidelines and determine appropriate entitlement volumes (EVs). These EVs will take into account the connective nature of groundwater systems, including their importance to groundwater dependent ecosystems and interaction with surface waters. This current project contributes to the SAFE project by quantifying the baseflow component of streamflow across Victoria over time using a digital recursive filter. This information will help to improve the understanding of the volume and timing of groundwater contributions to streamflow and will form an important dataset for use in the development of groundwater EVs. For this purpose, this current study aims to: Generate a Statewide data set of baseflow indices (BFIs) to streams using a consistent method; Undertake analysis of this data set to allow more detailed interpretation, including: Seasonal and annual flow duration curves of streamflow, baseflow and surface runoff for each location; Daily variability of BFI for each month; Assessment of trends in baseflow over time (at a subset of locations); and Control charts to help identify deviation in baseflow from reference behaviour in a predictive manner (at a subset of locations). These activities were undertaken in a staged approach, with data outputs progressively provided to DSE throughout the course of the project. In total, approximately 180 streamflow gauge locations were analysed in this study. This document provides an overview of the approach used to undertake the baseflow separation and the subsequent analysis. A brief summary of the data used for the study is also included, to provide an understanding of the basis of the analysis. Data outputs generated through this analysis have been provided in a package of text files and spreadsheets. SINCLAIR KNIGHT MERZ I:\VWES\Projects\VW06627\Deliverables\r01reb_BaseflowMethod.docx

Forward Melbourne Water is pleased to present the amalgamated Annual Report for the Hoddles Creek, Little Yarra and Don Rivers, Olinda Creek, Plenty River, Steels, Pauls and Dixons Creeks, Stringybark Creek, and Woori Yallock Creek Water Supply Protection Area Stream Flow Management Plans (the Plans) for the 2020-21 water year. Melbourne Water is responsible for the implementation, administration and enforcement of the Plans which were approved by the Minister administering the Water Act 1989 (Vic). This report has been prepared and submitted to the Minister for Water in accordance with section 32C of the Water Act 1989 (Vic). This report provides an overview of the surface water management activities administered under each Plan during the 2020/21 water year.

  • Functioning and Changes in the Streamflow Generation of Catchments
    Ecohydrology in space and time: functioning and changes in the streamflow generation of catchments Ralph Trancoso Bachelor Forest Engineering Masters Tropical Forests Sciences Masters Applied Geosciences A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2016 School of Earth and Environmental Sciences Trancoso, R. (2016) PhD Thesis, The University of Queensland Abstract Surface freshwater yield is a service provided by catchments, which cycle water intake by partitioning precipitation into evapotranspiration and streamflow. Streamflow generation is experiencing changes globally due to climate- and human-induced changes currently taking place in catchments. However, the direct attribution of streamflow changes to specific catchment modification processes is challenging because catchment functioning results from multiple interactions among distinct drivers (i.e., climate, soils, topography and vegetation). These drivers have coevolved until ecohydrological equilibrium is achieved between the water and energy fluxes. Therefore, the coevolution of catchment drivers and their spatial heterogeneity makes their functioning and response to changes unique and poses a challenge to expanding our ecohydrological knowledge. Addressing these problems is crucial to enabling sustainable water resource management and water supply for society and ecosystems. This thesis explores an extensive dataset of catchments situated along a climatic gradient in eastern Australia to understand the spatial and temporal variation
