I've offered to run a brief session on What's New in Python. This is a feature the Melbourne Python group is planning to start adding to its monthly meetings. Ideally the session would be very interactive - a chance for you to share any exciting recent developments you are aware of and learn from everyone else. I look forward to seeing you there if you can make it! :) Cheers, Ed -- Ed Schofield Phone: +61 405 676 229 From padarn at gmail.com Thu Apr 3 05:06:49 2014 From: padarn at gmail.com (Padarn Wilson) Date: Thu, 3 Apr 2014 14:06:49 +1100 Subject: [Canberra-PUG] Meeting Tonight Message-ID: Hi all, Sorry for the very late notice - someone kindly brought to my attention that there hadn't been a message sent out. There is a meeting on tonight at 6pm, G35 John Dedman (usual location). We have a few things lined up: Paul Leopardi is going to talk about PyClical/GluCat and Brenda Moon is going to tell us about Pyladies, PyConAU and some interesting things going on at MakeHackVoid. Details are mostly on the G+ event: https://plus.google.com/u/0/events/cs0jamp4s9n53h0co433tt1mur8?authkey=CLPz6f_Zy9TsogE Hope you can make it.

Please find the details of the May CPUG meeting below - Steve Roberts will be talking about a very interesting Open Source project performing scientific modelling of great importance (a joint initiative between Geoscience Australia and the ANU). We are always after more speakers for future CPUG meetings - if you would like to speak, please drop me an email gavin.jackson at gmail.com. A big shout out goes to Padarn Wilson for his contribution to organising CPUG events in the past, we wish him all the best in his endeavours in Germany. Also (if you haven't done so already), don't forget to join our Google+ community (https://plus.google.com/u/0/communities/103339628935802168974). The events feature is used to advertise and RSVP to upcoming CPUG events. *Topic* Using ANUGA to Model Tsunamis and Riverine Flooding *Time/Date* 6pm Thursday 1 May 2014 *Location* Australian National University John Dedman Building G35 (the Neumann Room) *Speaker*Stephen Roberts, Department of Mathematics, Australian National University *Abstract*The Australian National University (ANU) and Geoscience Australia (GA) have collaboratively developed an open source python software program called ANUGA, to model water flow and in particular inundation events. Using this software we can model the effects of natural hazards, such as riverine flooding, storm surges and tsunami, so as to obtain an understanding of the economic and social impact of these hazards on our urban communities. With these models we can help draft evacuation plans, design protective levees and design cities safely - reducing casualties and damage to property in communities affected by such disasters. A major capability of the ANUGA software is its ability to model the process of wetting and drying as water enters and leaves an area. This means it is suitable for simulating water flow onto a beach or dry land and around structures such as buildings. ANUGA is also capable of modelling difficult flows involving hydraulic jumps and rapidly changing flow speeds - the type of flows seen in extreme flooding and tsunamis. The core of ANUGA is the fluid dynamics module which is based on a finite-volume method for solving the shallow water wave equation. The study area is represented by a mesh of triangular cells. By solving the governing equation within each cell, water depth and horizontal momentum are tracked over time and the resulting flow is resolved. A very important and original attribute of ANUGA is the fact that it is open source and therefore available online free of charge for anyone with the knowledge to use it. Open Source is a very important phenomenon that really allows anyone to leverage off tools already developed to create better software tools in the future. In this talk I will give an overview of the way tsunamis are generated, and how the resulting flow propagates. It is critically important to understand the geometry and hydraulics of a particular problem - the sea bed and coastline can contribute in complicated ways to amplify a tsunami. For instance, why did some regions sustain catastrophic loss during the 2004 Boxing Day Tsunami, whereas neighbouring regions survived relatively unscathed? I will also discuss how we go about modelling these complicated flows on the computer. A user of our ANUGA software must specify the geometry (bathymetry and topography), the initial water level, boundary conditions such as tide, and any forcing terms that may drive the system such as wind stress or atmospheric pressure gradients. Often the biggest hurdle to obtaining a detailed impact model is the non-availability of reliable, high-resolution bathymetry and elevation data. Sometimes getting access to this data can be an interesting political as well as a scientific problem. Finally I will describe our experience in providing ANUGA as open source, and the very productive engagement we have had with users in developing and extending the software into flood modelling. *Additional References/Resources * http://anuga.anu.edu.au http://en.wikipedia.org/wiki/ANUGA_Hydro Cheers, Gav {e} gavin.jackson at gmail.com {mb} 0422 443 980 {skype} gavin6252 {twitter} @gavz {blog} www.gavinj.net {g+} profiles.google.com/gavin.jackson -------------- next part -------------- An HTML attachment was scrubbed...
