This report is one of a series of reports that present the methods and results from the development and calibration of surface water hydrological models for 26 Tasmanian catchments under both current and natural flow conditions. -
Hydro 4 Water Storage
TERM OF REFERENCE 3: STATE-WIDE WATER STORAGE MANAGEMENT The causes of the floods which were active in Tasmania over the period 4-7 June 2016 including cloud-seeding, State-wide water storage management and debris management. 1 CONTEXT 1.1 Cause of the Floods (a) It is clear that the flooding that affected northern Tasmania (including the Mersey, Forth, Ouse and South Esk rivers) during the relevant period was directly caused by “a persistent and very moist north-easterly airstream” which resulted in “daily [rainfall] totals [that were] unprecedented for any month across several locations in the northern half of Tasmania”, in some cases in excess of 200mm.1 (b) This paper addresses Hydro Tasmania’s water storage management prior to and during the floods. 1.2 Overview (a) In 2014, Tasmania celebrated 100 years of hydro industrialisation and the role it played in the development of Tasmania. Hydro Tasmania believes that understanding the design and purpose of the hydropower infrastructure that was developed to bring electricity and investment to the state is an important starting point to provide context for our submission. The Tasmanian hydropower system design and operation is highly complex and is generally not well understood in the community. We understand that key stakeholder groups are seeking to better understand the role that hydropower operations may have in controlling or contributing to flood events in Tasmania. (b) The hydropower infrastructure in Tasmania was designed and installed for the primary purpose of generating hydro-electricity. Flood mitigation was not a primary objective in the design of Hydro Tasmania’s dams when the schemes were developed, and any flood mitigation benefit is a by-product of their hydro- generation operation. -

Conditions Favouring Growth of Fresh Water Biofouling in Hydraulic Canals and the Impact of Biofouling on Pipe Flows
Conditions Favouring Growth of Fresh Water Biofouling in Hydraulic Canals and the Impact of Biofouling on Pipe Flows By Xiao Lin Li BEng(Hons.) Submitted in fulfilment of the requirements for the Degree of Masters University of Tasmania October 2013 Declaration of Originality This thesis contains no material which has been accepted for a degree or diploma by the University or any other institution, except by way of background information and duly acknowledged in the thesis, and to the best of candidates knowledge and belief no material previously published or written by another person except where due acknowledgement is made in the text of the thesis. …………………………………… Xiao Lin Li Date: 12/10/2013 Statement Concerning Authority to Access This thesis may be made available for loan and limited copying in accordance with the Copyright Act 1968. …………………………………... Xiao Lin Li Date: 12/10/2013 ii Abstract Abstract Biofouling increases frictional resistance and slows the water flow in fresh water canals and pipes. It results in up to 10% reduction in the flow carrying capacity in hydropower canals in Tasmania, Australia. This project investigated the effect of colour on the growth of biofouling in open channels and the impact of biofouling in pipes and penstocks. The effect of substratum colour on the growth of biofouling was studied by submerging mild steel plates painted with four different coloured epoxy coatings in fresh water. The plates were placed in a concrete lined canal for a period of time to allow biofouling to grow. Results show that black was the favoured colour for the growth of biofouling whereas the white plates developed the least amount. -
2010 Electricity Statement of Opportunities for the National Electricity Market
ELECTRICITY STATEMENT OF OPPORTUNITIES 2010 Electricity Statement of Opportunities for the National Electricity Market Published by AEMO Australian Energy Market Operator 530 Collins Street Melbourne Victoria 3000 Copyright © 2010 AEMO ISSN: 1836-7593 © AEMO 2010 ELECTRICITY STATEMENT OF OPPORTUNITIES © AEMO 2010 ELECTRICITY STATEMENT OF OPPORTUNITIES Preface I am pleased to introduce AEMO’s 2010 Electricity Statement of Opportunities (ESOO), which presents the outlook for Australia’s National Electricity Market (NEM) supply capacity for years 2013-2020 and demand for years 2010-2020. The supply-demand outlook reflects the extent of growth, and opportunities for growth, in generation and demand-side investment. This year, for the first time, AEMO has separated the 10-year supply-demand outlook into two documents. While the ESOO will cover years 3-10 and focus on investment matters, a separate document titled Power System Adequacy (PSA)–A Two Year Outlook will publish the operational issues and supply-demand outlook for summers 2010/11 and 2011/12. AEMO has released the ESOO and PSA together. The ESOO is one of a collection of AEMO planning publications that provides comprehensive information about energy supply and investment, demand, and network planning. AEMO’s other annual planning documents are the South Australian Supply and Demand Outlook, the Victorian Annual Planning Report and Update, the National Transmission Network Development Plan (NTNDP), and the Gas Statement of Opportunities. AEMO expects that climate change policies will, over time, change the way in which Australia produces and consumes electricity. This is likely to take place through a shift from the current reliance on coal as a source of generation to less carbon-intensive fuel sources. -

Googk A CATALOGUE OF THE MINERALS KNOWN TO OCCUR IN TASMANIA, WITH NOTES ON THEIR DISTRIBUTION• .Bv W. F. PETTERD. THE following Catalogue of the Minerals known to occur and reeortled from this Island is mainly prepared from specimen~ contained in my own collection, and in the majority of instances I have verified the identifications by careful qualitative analysis. It cannot claim any originality of research, 01' even accluac)" of detail, but as the material has been so rapidly accumulating during the past few )'ears I bave thoug-ht it well to place on record the result of my personal observation and collecting, wbich, with information ~Ieaned from authentic sources, may, I trust, at least pave tbe way for a more elaborate compilation by a more capable authority. I have purposely curtailed my remarks on the various species 80 Rs to make them as concise as possible, and to redulle the bulk of the matter. As an amateur I think I may fairly claim tbe indulgence of the professional or otber critics, for I feel sure tbat my task has been very inadequately performed in pro portion to the importance of the subjeot-one not only fraugbt with a deep scientific interest on account of tbe multitude of questions arisin~ from the occurrence and deposition of the minerals them selves, but also from the great economic results of our growing mining indu.try. My object has been more to give some inform ation on tbis subject to the general student of nature,-to point out tbe larg-e and varied field of observation open to him,- than to instruct the more advanced mineralo~ist. -
