Active River Management explained – what drives it and why?

Start time: 6:00pm AEST, 8th June 2021

Free webinar but pre-registration is mandatory for access to the platform

Overview

Management rules in regulated systems are in place to supply water and protect the environment through environment flow rules.

Have you ever wondered how it works? Why we have the Water Sharing Plans?

Tim Hosking will be discussing the policy and science behind active river management and Dan Berry the implementation and operation of the regulated rivers.

Active Management of rivers for the environment, community, and economy.

It takes a lot of work to put, the right amount of water, in the right place, at the right time. WaterNSW ensures rivers rise and fall with environmental water while also scheduling access to water by towns and irrigators with releases from dams and weirs.

Uses of Water for the Environment in the Macquarie catchment

Water for the Environment has been managed in the Macquarie River since 1980 – with the only thing consistent over that time being the controversy. A case study of 4.5 recent real-life uses of Water for the Environment will be presented to help illustrate why Tim struggles whenever someone asks what he does for a living.

Speakers

Dan Berry

Manager Water System Operations, WaterNSW

Dan is responsible for implementation of statewide bulk water operations for; the Greater Sydney supply, as well as rural NSW. This includes the development of annual operating plans, flood operations, and the management of numerous decision support systems.

Dan’s career theme has been as a practitioner in integrating all the aspects of water reform, particularly directing these reforms to achieve environmental and productivity outcomes. Dan has a proven record in identifying and implementing changes that increase efficiency in water delivery and increase the value of these services to both customers and the environment.

Dan has over 35 years’ experience with WaterNSW and its predecessors. He has a degree in civil engineering and has completed a substantial portion of an MBA.

Tim Hosking

Senior Wetlands and Rivers Conservation Officer. NSW Department of Planning, Industry and Environment

Tim works as part of a regionally-based team within DPIE who work to maintain and improve the health of wetlands and aquatic ecosystems across north west NSW catchments. Currently his focus is on the Macquarie-Cudgegong catchment, with the main tool for this task being to manage Water for the Environment in collaboration with the Commonwealth Environmental Water Office.

Tim has a multi-disciplinary background including environmental engineering, environmental impact assessment, ecology, strategic and statutory planning, and now as a natural resource manager – which is lucky, as environmental water management is an entirely silo-busting occupation.

Tim has a combined degree in Environmental Engineering and Natural Resources Management, with postgrad studies in Urban and Regional Planning.

Monitoring COVID in Wastewater

Our next presentation is will cover some different perspectives on the monitoring of COVID in waster water systems. We are pleased to have a balanced perspective here with:

  • Prof. Gertjan Medema, Principal Microbiologist, KWR Water Research Institute
  • Dr Kaye Power, Principal Public Health Advisor for Sydney Water

to give a combined European and Australian perspective.

6pm 8th December 2020 (Sydney time)

Scrivener Dam: Assessing Dam Safety through Physical Modelling

The next Water Panel webinar is schedule for 4:00pm on Wednesday 30 September and is free for EA members but pre-registration is required.

Scrivener Dam is a critical piece of Canberra’s infrastructure, maintaining water levels of the iconic Lake Burley Griffin. Like all dams in Australia, it requires regular maintenance and assessment to ensure ongoing safe operation.

A recent inspection identified potential for undesirable uplift forces under the stilling basin slab, triggering a more detailed assessment of dam stability. This included a 1:40 scale physical model by the UNSW Water Research Laboratory (WRL) for the National Capital Authority. The model was used to measure water dynamics for the dam at critical flood conditions, with a focus on dynamic pressures within the stilling basin.

This presentation will discuss findings and the unique advantages and limitations of physical hydraulic modelling. It will be streamed live from WRL and includes a live demonstration of model flows.

This event will be co-presented by WRL’s Dr Laura Montano and Ben Modra.

We have a PDF available with full details.

Are we still lossed about Losses?

The next Panel presentation will be delivered online via WebEx on Tuesday 14th July 2020 starting at 5pm sharp. Event is free for EA Members but pre-registration is required.

It is expected that as temperatures increase, extreme precipitation will increase resulting in more severe flooding. However, in Australia, there is significant evidence of decreasing flood maxima, despite increases in extreme rainfall.

This online webinar will explore changes in flood timing and magnitude from the AWRA-L. The result is a ‘worst of both worlds’ scenario whereby the rare flood events that are used in design of infrastructure are increasing, but smaller events, critical for water supply and dam storage are decreasing.

Call for Abstracts for HIWE2020

The first call for abstracts for the 2020 Hydraulics in Water Engineering is now live. Please check out all the details on the conference website and, to be nice to the organisers, submit an abstract early.

Video Posted From Palaeoclimate and Drought Presentation

Thanks to the presenters we have posted the video of the presentation on our YouTube Channel, or check it out right here:

Managing droughts and water security – getting maximum value from palaeoclimate records

Introduction

The next panel presentation, which is incredibly relevant to the current drought, is scheduled for:

26th November 2019
BoM Elizabeth Street Office
Register/Network from 5:30pm
Formal Start: 6:00pm

We already have a lot of interest for this so please ensure that you pre-register to ensure your place.

Abstract

Droughts cause significant problems in Australia. However, we still do not know the true chance of a drought occurring or how reliable existing infrastructure is for dealing with current and future drought impacts. This talk (i) summarises recent research that demonstrates how drought risk changes due to multidecadal climate variability and (ii) discusses the implications of this for water management, policy and infrastructure.
