water APRIL 2015 68 Feature article for intermediate and high emissions scenarios were considered as well as near- and long-term future periods. These results indicate that the future may hold stronger thermal stratification, resulting in conditions more suitable for cyanobacterial growth. Increases in both the median and 95th-percentiles of cyanobacterial biomass were found, concurrent with a decrease in abundance of competitor groups such as green algae and diatoms. Furthermore, a change in seasonality was implied, with greater cyanobacterial growth into autumn. This analysis considered the direct effect of climate change, while further impacts may occur via impacts on catchment processes, such as nutrient cycling and transport. These impacts will be tested using integrated modelling schemes, consisting of coupled catchment and reservoir models to evaluate the direct versus indirect impacts to water quality resulting from climate change. The data will also be used to evaluate the best operating practice to mitigate these impacts by testing the ability of artificial destralification, multi-level offtakes and catchment remediation to prevent negative impacts. This data will help to inform future investment decisions about the type and scale of water treatment infrastructure required in South Australia. wj suMMaRy The downscaled climate projections for the eight NRM regions of SA from the Goyder Institute Climate Change project have allowed one of the most detailed modelling efforts to be conducted into water security of an Australian city. The modelling for the AMLR NRM region indicates that it is expected to be drier and hotter with projected decreases in rainfall for all seasons. Average temperatures (maximum and minimum) are projected to increase for all seasons. Slightly larger increases in maximum temperature occur for the spring season, corresponding to its increased drying. These findings have major implications for the quantity and quality of water that is collected in the reservoirs in the AMLR NRM, and will enable water resource and catchment mangers to assess the security of future water supplies and protect water supplies for all water users. aCKnowledgeMents This work was financially supported by the Goyder Institute for Water Research, a partnership between the South Australian Government through the Department for Environment, Water and Natural Resources, CSIRO, Flinders University, the University of Adelaide and the University of South Australia.

Discounts apply for early registrations, dual seminar bookings and multiple registrations from the one organisation. We can also run these seminars at your own workplace or customise them to suit your needs. In addition to our standard public seminar range, we also have other customised seminars that are run regularly at treatment plants and in offices around the country. These seminars include: Pump Basics This one day seminar is run for the benefit of operations and maintenance staff so that they will be better equipped to understand how the common types of pumps should be operated and maintained. A particular emphasis is placed on understanding performance curves and piping system characteristics (e.g. static head, back pressure and head losses versus flow rate) so that trouble-shooting skills can be improved. Water/Wastewater Pumping & Piping Fundamentals Based on a combination of our standard “Pump Fundamentals” and “Liquid Piping Systems Fundamentals”, this seminar is run over two days. The material presented is specifically related to the pumping equipment, piping, valves, instruments, ancillaries and pipeline setups found in municipal treatment plants and pump stations. Many worked example problems are presented which demonstrate the steps involved in designing pumping and piping systems. Troubleshooting tips and potential remedial measures for under-performing systems are also discussed in detail. Mechanical Plant & Equipment This three day seminar is best suited to those who are involved in either the design, operations or maintenance of plant and equipment specifically used for fluid centric processes. Such equipment can be found on larger treatment plants which also incorporate biogas plants. The topics covered include: liquid and gas piping systems, valves, instruments, fuel gas systems, compressed air systems, steam systems, blowers, compressors, pumps, fans, rotary feeders, motors and engines and much more. Safety-in-Design Fundamentals For Australian Designers (e-Learning Course) Our first online (e-learning) course has been up-and-running since March of last year. The purpose of this three hour course is to provide basic instruction and guidance on the WHS obligations of designers in Australia as well as provide recommendations on how best to fulfil these obligations thereby providing safer designs. This course and the training materials are accessed through the KASA Redberg learning management system. Login details are provided to registrants via email after their online payment (i.e. credit card or PayPal) has been processed. The process of registra- tion, payment and receipt of login details only takes a few minutes.
