This supports the master planning by providing engineering input to assist in the development of an Indicative Layout Plan (ILP). The strategy has been developed using an integrated approach to flood risk management and water sensitive urban design and streambank management principals, meeting relevant standards. The objective of the Water Cycle Management Strategy (WCMS) is to: . Identify the stormwater and flood management issues to be taken into account in the future development of the Precinct; . Identify flood impacts and an appropriate flood evacuation strategy for the Precinct; . Assess the existing streambank conditions, likely development impacts on streambank condition and appropriate management techniques; and . Identify appropriate options and locations for the control of the quantity and quality of stormwater leaving the site. This document outlines the methodology adopted in assessing flooding, water quality and streambank erosion; the Water Cycle Management Strategy ensures the proposed development meets requirements with regards to the management of impacts on waterways, the receiving environment and public safety relating to flooding. Flood modelling has been completed to assess the effectiveness of the Precinct’s water quantity management strategies. The flood assessment shows that post-development 1% Annual Exceedance Probability (AEP) flows are controlled and contained within the proposed detention basins and riparian corridors of the Precinct. The strategy provides a balance between maintaining riparian corridor functions, providing floodplain management and meeting development outcomes. The water quality strategy developed for the Precinct will also ensure that the quality of stormwater discharging from the Precinct meets the requirements of Camden Council and will ensure potential stormwater pollutant impacts are mitigated. A comprehensive assessment of streambank stability has been undertaken so that Lowes Creek has low to moderate bank erosion under existing flow and channel conditions. Under post-development conditions, erosion would increase if no mitigation measures were adopted. An analysis of the modelling results showed that increased erosion during post-development conditions was not a result of increasing peaks but of increasing flow durations where excess shear stresses occur. These modelling results emphasise the notion that just looking at peak flows is not sufficient, as erosion is the product of the magnitude of the excess stress, times the duration of that excess stress. Proposed bank erosion mitigation measures include small drop structures along Lowes Creek and a portion of the Western Tributary. These measures would ensure that erosion is not increased as a result of the proposed Precinct development, while also minimising the disturbance to the existing riparian corridor vegetation. This document will be placed on public exhibition for review and comment by interested stakeholders. Comments and input received as an outcome of this process will be considered and addressed, as appropriate. 80215038 | 26 September 2018 Cardno iii Lowes Creek Maryland Precinct Water Cycle Management Study Table of Contents 1 Introduction 1 1.1 Objective of the Report 1 1.2 Scope of Work 1 1.3 Lowes Creek Maryland Precinct 2 1.3.1 Location 2 1.3.2 Precinct Planning Context 2 1.4 Water Cycle Management Strategy 5 1.5 Draft Indicative Layout Plan 6 2 Available Data 7 2.1 Development Guidelines 7 2.1.1 Growth Centres Development Code 7 2.1.2 Camden Growth Centre Precincts Development Control Plan 7 2.1.3 Guidelines for Controlled Activities on Waterfront Land 9 2.1.4 Camden Councils Engineering Design Specification 10 2.2 Upper South Creek Floodplain Risk Management Study and Plan 10 2.2.1 FRMS&P Review and Update 10 2.3 Survey Data 10 3 Consultation 12 3.1 Riparian Corridors 12 3.2 Hydrologic, Hydraulic and Water Quality Modelling 12 3.3 Australian Rainfall and Runoff 2016 14 3.4 Online Basins 15 4 Flood Assessment 16 4.1 Study Area 16 4.2 Data Review 18 4.2.1 Digital Elevation Model 18 4.2.2 Existing Farm Dams 19 4.3 Hydrologic Model Setup 20 4.3.1 IFD Data 20 4.3.2 Temporal Patterns 21 4.3.3 Perviousness, Storm Losses & Surface Roughness 22 4.3.4 Pre-Burst Rainfall and Burst Losses 22 4.3.5 Pre-Development Catchment Delineation 23 4.3.6 Post-Development Catchment Delineation 25 4.3.7 Flow Routing 26 4.3.8 Critical Duration & Median Temporal Patterns 26 4.4 Pre-Development Hydraulic Model Setup 26 4.4.1 Terrain 26 4.4.2 Inflow Hydrographs 26 4.4.3 Downstream Boundary Conditions 27 4.4.4 Surface Material Types 27 4.4.5 Existing Hydraulic Structures 27 4.5 Model Validation 29 4.6 Pre-Development Hydraulic Modelling Results 29 4.6.1 Lowes Creek 29 4.6.2 Culvert Crossing at The Northern Road 29 80215038 | 26 September 2018 Cardno iv Lowes Creek Maryland Precinct Water Cycle Management Study 4.6.3 Western Tributary 29 4.6.4 Central Tributary 29 4.6.5 Northern Western Tributary 30 4.7 Post-Development Hydraulic Model Setup 30 4.7.1 Terrain 30 4.7.2 The Northern Road Upgrade 33 4.7.3 Riparian Corridor Works 33 4.7.4 Proposed Hydraulic Structures 34 4.8 Post-Development Hydraulic Modelling Results 36 4.8.1 Lowes Creek 36 4.8.2 Culvert Crossing at The Northern Road 36 4.8.3 Western Tributary 36 4.8.4 Central Tributary 36 4.8.5 Northern Western Tributary 36 5 Flood Emergency Response Strategy 37 6 Stormwater Quantity Management Strategy 39 6.1 Modelling Approach 39 6.1.1 Post-Development Scenario Model Set-Up 39 6.1.2 Modelling of Detention Basins 39 6.2 Basin Strategy 39 6.2.2 Basin Design Principles 40 6.3 Proposed Online Detention Basins 41 6.3.1 Western Online Basin 42 6.3.2 Central Online Basin 42 6.4 Proposed Offline Detention Basins 43 6.4.2 Offline Basin Performance 43 6.5 Comparison of Peak Discharge Flows 44 7 Water Quality Management 45 7.1 Background 45 7.1.1 Pollutant Reduction Targets 45 7.1.2 Water Quality Treatment Approach 45 7.2 Water Quality Modelling 47 7.2.1 Rainfall Data 48 7.2.2 Evapo-Transpiration Data 48 7.2.3 Rainfall Runoff Parameters 48 7.2.4 Pollutant Generation 49 7.2.5 Model Layout 50 7.2.6 Catchment Details 50 7.2.7 Modelling of Gross Pollutants Traps 51 7.2.8 Modelling of Bio-retention Basins 51 7.2.9 Overall Precinct Treatment Performance 52 7.3 Summary 53 8 Streambank Condition Management 54 8.1 Approach to Streambank Condition Assessment 54 8.2 Field Investigations 55 8.2.1 Rapid Geomorphic Assessments 55 8.2.2 Detailed Site Data Collection 56 8.3 Bank-Erosion Modelling 60 80215038 | 26 September 2018 Cardno v Lowes Creek Maryland Precinct Water Cycle Management Study 8.3.1 Flow Data for BSTEM Simulations 60 8.3.2 Existing Conditions 61 8.3.3 Proposed Conditions 61 8.3.4 Erosion Mitigation Measures 62 8.4 Summary of Results 65 9 Operations and Maintenance 70 10 Conclusions 72 11 Glossary 73 12 References 74 Appendices Appendix A Draft Indicative Layout Plan Appendix B XP-RAFTS Catchment Details Appendix C Flood Behaviour Figures Appendix D ARR2016 Data Tables Table 2-1 Stormwater Detention Upper (PSD) and Lower (SSR) Limits 9 Table 2-2 Water Quality and Environmental Flow Targets 9 Table 3-1 Feedback

GWP was created to foster Integrated Water Resources Management (IWRM), which aims to ensure the co-ordinated development and management of water, land, and related resources by maximising economic and social welfare without compromising the sustainability of vital environmental systems. GWP promotes IWRM by creating fora at global, regional, and national levels, designed to support stakeholders in the practical implementation of IWRM. The Partnership’s governance includes the Technical Committee (TEC), a group of internationally recognised professionals and scientists skilled in the different aspects of water management. This committee, whose members come from different regions of the world, provides technical support and advice to the other governance arms and to the Partnership as a whole. The Technical Committee has been charged with developing an analytical framework of the water sector and proposing actions that will promote sustainable water resources management. The Technical Committee maintains an open channel with the GWP Regional Water Partnerships (RWPs) around the world to facilitate application of IWRM regionally and nationally. Worldwide adoption and application of IWRM requires changing the way business is conducted by the international water resources community, particularly the way investments are made.

  • Managing the Urban Water Cycle in a Changing Environment
    Water Utility Journal 9: 3-12, 2015. © 2015 E.W. Publications Managing the urban water cycle in a changing environment R. Proença de Oliveira, J. Saldanha Matos and A. J. Monteiro CERIS - CEHIDRO, Civil Engineering Research and Innovation for Sustainability, Department of Civil Engineering, Architecture and Georesources, Instituto Superior Técnico, Technical University of Lisbon, Portugal e-mails: [email protected], [email protected], [email protected] Abstract: Climate change will likely lead to higher climate variability which must be addressed by increasing the robustness, flexibility and resilience of urban water cycle systems. Other anthropogenic pressures such as urbanisation, population growth and other landscapes and watershed changes add to climate related stresses. The urban hydrological cycle is becoming more complex to manage and actions have to be planned and implemented in a context of increasing uncertainty. Urban water systems managers need to plan the transition of their current system into a more sustainable future, assuming a fundamental and widespread paradigm shift on how urban water cycles are managed. Sustainability and resilience have become the keywords. In Portugal, the Sectoral Strategy on the Adaptation to the Impacts of Climate Change on Water Resources addresses the climate related issues facing water service managers. It includes six specific programs for urban water cycle management, namely the promotion of water use efficiency, the diversification and reinforcement of water supply sources, the improvement of quality control and water treatment capacity for human consumption supply, the review and upgrade of wastewater drainage and treatment systems, flood risk management, and research and knowledge enhancement.

  • A Modelling Tool to Inform City Scale Integrated Water Cycle Management Plans
    A modelling tool to inform city scale integrated water cycle management plans Shiroma Maheepala1, Ashis Dey2 and Fareed Mirza1 1CSIRO, 37 Graham Road, Highett, Victoria 3190, Australia; [email protected]; [email protected] 2eWater, Innovation Centre, University Drive, Bruce, ACT 2617, Australia; [email protected] Abstract Integrated Water Cycle Management (IWCM) is an alternative approach for the traditional management of urban water systems. In recent times, there has been an increased interest for incorporating IWCM principles into urban water systems planning. This is to maximise the productivity, liveability and resilience of urban areas. The first step of adopting IWCM principles is development of an IWCM Plan. However, development of an IWCM plan for a town or a city is a complex task. It requires identifying urban water management options that have the potential to contribute towards achieving IWCM principles, understanding their hydrological, water quality, economic, social and environmental implications, and evaluating them to identify the most effective options that have the potential to maximise IWCM objectives. There are multiple objectives to satisfy. Therefore, there can be many different ways to provide water services, but not all solutions can best meet the objectives. Identifying the most efficient options that can best meet a given set of objectives cannot be done manually. A modelling tool is essential to evaluate the options and identify trade-offs between them. The focus of this paper is to demonstrate the applicability of Source, a modelling tool specifically developed to address Integrated Water Resource Management in river basins, to inform the development of IWCM Plans in cities.

  • Guidance on Water Supply and Sanitation in Extreme Weather Events
    UNITED NATIONS ECONOMIC COMMISSION FOR EUROPE Guidance on Water Supply and Sanitation In Extreme Weather Events Edited by L Sinisi and R Aertgeerts Guidance on Water Supply and Sanitation In Extreme Weather Events Extreme weather events, including floods and droughts, are increasing in frequency and intensity. They affect the operation of water-supply, drainage and sewerage infrastructure, and the functioning of wastewater treatment plants, thereby affecting the protection of public health. Parties to the Protocol on Water and Health reviewed experience and good practice in Europe through a broad consultative process, to devise the present guidance. This publication describes how adaptation policies should consider the new risks from extreme weather events, how vulnerabilities can be identified and which management procedures can be applied to ensure sustained protection of health. It takes an integrated environment-and-health approach and addresses cross-cutting issues, such as the role of the health and environment sectors in extreme weather, the need for policy dialogue and multisectoral partnership to assess and control risks, and the challenges of different settings (such as urban and rural, small and centralized large- scale supplies). The publication is aimed at a broad audience, including policy-makers; environment, health and water-resources professionals; and water service managers. The following partners contributed to the preparation of the guidance. drinking water inspectorate World Health Organization Regional Office for Europe Scherfigsvej 8, DK-2100 Copenhagen Ø, Denmark Tel.: +45 39 17 17 17.

  • Integrated Water Cycle Management: “An Australian Perspective”
    European Water 15/16: 23-32, 2006. © 2006 E.W. Publications Integrated Water Cycle Management: “An Australian Perspective” G. Khouri Business Development Environment & Water Resources, Worley Parsons (Incorporating JWP) [email protected] Abstract: Integrated Management of Water Resources including stormwater and waterways is potentially one of the most influential factors in shaping our urban centres and our standards of liveability, now and in the future. Australia has a high water usage coupled with low and uncertain rainfall (Yencken and Wilkinson, 2000). Local governments in Australia are under enormous pressure to manage the significant future population growth in a sustainable manner. In order to be a sustainable and liveable region, local governments and the development industry need to work cooperatively to manage water resources and to protect natural assets. The traditional approach to managing water, at a government level, involves a number of departments looking after different water components. For example, at a Queensland State level, the Environmental Protection Authority (EPA) regulates water quality, while the Department of Natural Resources & Mines (DNRM) regulates water quantity. At a local government level the water authority provides supply and sewerage, while stormwater is managed by a different department and water sensitive urban design by another. Emerging ideology in the management of water supply is towards demand management. Demand management involves looking at efficient use of water through reducing losses, improving water usage efficiencies and source substitution. A holistic approach to demand management is through Integrated Water Cycle Management (IWCM). IWCM requires an integrated institutional approach to implement effectively. Water supply, sewerage and stormwater are the three key elements of IWCM, but are traditionally designed independently.
