ARR2016: Uncertain about uncertainty?

UNSW short course in statistics and probability to support ARR2016

The release of Australian Rainfall and Runoff 2016 has focused interest on a range of sophisticated approaches for flood hydrology based on different statistical methods. This course provides an introduction and refresher of aspects of probability and statistical theory used throughout ARR2016. Attending this course will give you with the skills to best understand the theory behind the new ARR2016 methods and datasets available.

Australian Rainfall and Runoff Climate Change Guidelines Launch

Speaker: Bryson Bates
Wednesday 26 November 2014, 4-5.30pm
Australian Rainfall and Runoff will be launching its Interim Climate Change Guidelines at the Engineers Australia National Convention 2014. These guidelines were lead by Dr Bryson Bates from CSIRO. This draft discussion paper draws on the most recent climate science, particularly the release of the IPCC Fifth Assessment Report on the Physical Science Basis in September 2013 (IPCC, 2013) as well as the new climate change projections for Australia (CSIRO and BoM, 2014), and outlines an approach to address the risks from climate change in projects and decisions that involve estimation of design flood characteristics. For consistency with the revised IFD design estimates for Australia, the Interim Guideline is intended to be applied to current-day rainfall intensities with a probability of one exceedance per year or annual exceedance probabilities (AEPs) from 50% to 1%.

Australian Rainfall and Runoff Revision Project 18 – Interaction of Coastal Processes and Severe Weather Events

Speaker: Seth Westra, Michael Leonard
Thursday 27 November 2014, 3.30-5 pm
Australian Rainfall and Runoff Revision Project 18 focused on the Interaction of Coastal Processes and Severe Weather Events. This session  will include an overview of the methodology and a demonstration of the software developed by the University of Adelaide. This project will address the current short coming in estimating flood behaviour in the estuarine zone for current and future climate conditions.

To register please go to the Convention Website. Follow the normal registration process for the Convention. The system asks you to choose what you want to attend to calculate the fee to be charged. While the Convention has a number of workshops running the registration page is only showing them as ‘Wednesday Workshop’ and ‘Thursday Workshop.’ So depending upon the day you want to attend, you can register for one or both. Registration costs $195 per workshop.

ARR Update for August 2012

Project Updates

Project 4 (Continuous Rainfall Sequences at a point)

The Stage 2 report on Continuous simulation of rainfall sequences has been released for industry comment. Continuous simulation of rainfall sequences are becoming increasingly important in design flood estimation as they represent, arguably, the most rigorous technique available to represent the joint behaviour of flood-producing extreme rainfall events, the preceding antecedent rainfall conditions, and the influence of non-stationary catchment conditions. This report describes the outcomes from the second stage of ARR research project 4. The objectives of this stage are to:

  1. finalise the development of the regionalised state-based method of fragments approach as well as the development of a regionalised daily rainfall generation model; and
  2. assess the performance of the method of fragments model using the same statistics and locations that were used in Frost et al [2004].

Arising from this project, methods were developed to allow for the generation of sequences of point-rainfall at the resolution of the pluviograph data (in this study taken to be in increments of 6-minutes) at any location in Australia. The testing conducted in this phase of work focused on statistics relevant for using continuous simulation in flood frequency estimation. Specifically, the method was tested in the context of the capacity to reproduce both extreme rainfall and the antecedent rainfall leading up to the annual maxima event, with the suite of methods generally performing well against these metrics.

ARR Update July 2012

Project Updates

Project  5 (Regional Flood Methods)

In Australia, there are many streams where there is little/no recorded streamflow data. In these ungauged and poorly gauged catchments, there is insufficient information/data to obtain design flood estimates which are needed to size hydraulic structures, plan and design other water infrastructure and undertake various environmental and ecological studies. Regional flood frequency analysis (RFFA) is the most commonly adopted technique to derive design flood estimates on the ungauged catchments. A RFFA method attempts to transfer flood characteristics information from a group of gauged catchments to an ungauged catchment of interest. The RFFA methods recommended in the Australian Rainfall and Runoff (ARR) in 1987 need updating to reflect the advancements in RFFA methods and new additional streamflow data. find out more here

Project  10 and 15 (People Safety and Flow around buildings)

The final seminar on Flow around buildings and People Safety will be held at the 19th Queensland Water Symposium on 27-28 Sep in Brisbane. A large number of the profession have attended seminars held in Hobart, Perth, Melbourne, Newcastle, Darwin, and Sydney earlier this year.

Project 18  (Interaction of Coastal and Riverine flooding)

Flooding in the lower reaches of many coastal catchments can result from runoff generated by an extreme precipitation event occurring over the catchment, and/or elevated tail water levels attributable to a combination of high astronomical tide and storm surge. In many cases these flood-producing processes are the result of common meteorological conditions, with elevated storm surges being more likely to occur on days with extreme inland precipitation than on other days. This issue, referred to as joint dependence, can result in higher flood levels compared to the case where these processes are independent. The stage 2 report for Project 18 (Interaction of Coastal and Riverine Flooding) has been released for industry comment and is now available on the ARR webpage. http://www.arr.org.au/Website_links/ARR_Project18_Stage2_Report_Final.pdf

This report presents the outcomes of a pilot study into the application of statistical joint probability methods on extreme rainfall and storm surge in the coastal zone, with a view to providing guidance on the degree of interaction between these two physical process, as well as describing how this information should be applied for the estimation of flood risk along the Australian coastline. As part of this study, three separate areas of work were conducted: (1) the compilation of a large dataset of historical storm tide records at a number of locations along the Australian coastline, which when combined with the existing records of daily and sub-daily rainfall, can form the basis of an empirical study on the joint dependence between these variables; (2) a review of the statistical extreme value modelling literature with the objective of developing a model that can identify the strength of dependence between these variables; and (3) the identification of a methodology by which information on dependence between extreme rainfall and storm surge can be translated to a flood variable (such as a flood level or flow rate) at any location along the Australian coastline.
