Expressions of Interest Sought in a Workshop on Design Flood Flow Estimation for Floodplain Management in Brisbane
June 19, 2001
The Water Panel, Institution of Engineers Australia, Qld Division, the CRC for Catchment Hydrology and the Department of Civil Engineering, Monash University are seeking expressions of interest to attend a Workshop on Design Flood Flow Estimation for Floodplain Management in Brisbane during 24-25 September 2001
WORKSHOP AIMS AND SCOPE
***********************
This workshop is aimed at flood designers and flood management practitioners with basic to intermediate experience in design flood estimation, giving them an opportunity to update their design flood estimation skills and become familiar with new approaches.
It will deal with currently applied design flood flow estimation methods, new developments and practical issues in their application. In a 'hands-on' session, participants will be able to apply selected flood frequency analysis methods to practical example situations, and during the other sessions, there will be opportunities to discuss specific issues with a group of experts. An outline of the proposed workshop sessions is given below.
It is intended that this workshop will be followed next year by workshops on hydraulic modelling (flood level estimation) for floodplain management and risk management in design of flood mitigation measures.
THE PRESENTERS
**************
Professor Russell Mein is the Director of the Cooperative Research Centre for Catchment Hydrology (CRCCH). Russell has extensive experience in all aspects of catchment hydrology and was the leader of the CRC's Flood Hydrology Program (completed in 1999). He is a co-author of the runoff routing package RORB, and was Chair of the Advisory Committee which oversaw the production of the 1987 edition of 'Australian Rainfall and Runoff'.
Dr Ian Rutherfurd is a Senior Lecturer at the Department of Geography and Environmental Studies, The University of Melbourne. Ian is a geomorphology expert who is actively involved in many river and catchment management activities. He is the leader of the CRC's River Restoration Program and was the project leader responsible for the production of the Stream Restoration Manual.
Mr Erwin Weinmann is a Senior Lecturer at the Department of Civil Engineering, Monash University. Previously, he was the Rural Water Commission's Principal Hydrologist and was responsible for many flood studies. Erwin has wide-ranging experience in design flood estimation and is the co-author of the revised Book VI of 'Australian Rainfall and Runoff' - Estimation of large to extreme floods.
A number of Queensland flood estimation experts and practitioners will also be involved in the workshop presentations to ensure that relevant local issues can be addressed. A more detailed program giving details of these speakers will be made available closer to the workshop date.
COST AND REGISTRATION OF INTEREST
*********************************
The proposed registration fee for the workshop (2 days) is $660 (incl. GST) and will include a set of the Course Notes for the workshop sessions plus lunch, morning and afternoon teas.
At this stage, the workshop organisers need an expression of interest from potential workshop participants to allow workshop preparations to proceed. If a substantial interest in the workshop is confirmed, a flyer with workshop registration details will be issued in July.
Please contact the Institution of Engineers with your expression of interest by 6th July 2001:

OUTLINE OF WORKSHOP SESSIONS
***************************
Session 1 The geomorphological setting for the catchment-stream-floodplain system [Ian Rutherfurd]
This introductory session will look at the role of geomorphological factors in the development of catchment features and in the evolution of the stream-floodplain system, focusing on the specific characteristics of Australian streams. It will show that a good understanding of the dynamic nature of catchment-stream-floodplain systems, the impacts of human interventions and the ecological role of floodplains is important to floodplain management.
Session 2 What factors determine the size of floods and how do different flood estimation methods allow for them? [Russell Mein]
This session will look at the hydrologic factors that cause floods, and the natural and anthropogenic factors that may modify them. It will also give an overview of the most commonly used flood estimation methods in Australia, and the situations they are typically applied in.
Session 3 Flood frequency analysis - Australian practice [Erwin Weinmann]
The emphasis of this session will be on the issues involved in applying the currently recommended flood frequency analysis methods in practical situations. New developments towards the revision of the flood frequency analysis chapter in Australian Rainfall and Runoff will also be discussed.
Session 4 Practice session on flood frequency analysis [E Weinmann, R Mein]
During this practice session in a computer lab, participants will have an opportunity to work through several instructive examples of flood frequency analysis to develop an understanding of how flood information can best be used to derive reliable flood frequency estimates.
Session 5 Rainfall-based design flood estimation - effective application of conceptual runoff routing models [Russell Mein]
The emphasis of this session will be on developing a better understanding of the strengths and limitations of models like RORB and URBS, and helping practitioners to overcome any model limitations for the application in specific situations. Possible approaches will be illustrated by examples, and there will be opportunity for discussion of specific issues.
Session 6 Runoff routing parameters for design flood applications [R Mein, E Weinmann and Qld expert]
The purpose of this session is to assist practitioners in selecting appropriate parameter values for a particular runoff routing model application. Issues like the conceptual/physical basis of model parameters, interpretation of calibration results, extrapolation to different conditions or extreme events, and parameter estimates for ungauged catchments in Qld will be discussed.
Session 7 New developments in design rainfall and loss data for Qld
[E Weinmann, R Mein and 2-3 Queensland experts]
This session is intended to bring participants up-to-date with what is being done to provide practitioners with improved design data and with easier access to existing data, specifically for Queensland catchments. A number of people directly involved in developing new design data (e.g. design rainfall data for Rare to Extreme events) will be introducing the new developments.
Session 8 Design flood estimation - local case study examples [3 Qld practitioners] This session will demonstrate how some of the issues raised in the previous sessions have been addressed in practical project situations, with an opportunity to discuss particular issues after each presentation. It is intended to have 3 local case studies representing significantly different situations, presented by representatives of different Queensland organisations.
