The ANUGA finite volume numerical model

  • ANUGA is open-source software for the

simulation of the shallow water equation.

  • Open source development is led by the Australian

National University and Geoscience Australia.

  • Used to analyse flood, tsunami, dam-break,

bridge design, river restoration, erosion management…

  • Written in Python (most) and C (computational

components) https://github.com/GeoscienceAustralia/anuga_core

vs

Traditional Flood Study

  • Stored on a specialist’s hard-drive.
  • Hard to update.
  • Hard to manage change.
  • Expensive licensing can restrict

stakeholder access for scenario testing Online Flood Study

  • Stored in Geonode.
  • Update online.
  • Can track change.
  • Open source model licensing

allows for accessible scenario testing and collaboration.

Some lessons learned

  • Commit to a cloud vendor, but no too much (for example, use IaaS, not Paas)
  • Always script the server build process (for example: vagrant, shell scripts and ansible)
  • The most effective way to namespace data in this case is to prepend identifiers onto any

data filenames when they are uploaded or created: merewether_dem_myfreeformLayerNameHere.shp These datasets can then be filtered/classified/secured by the UI or APIs as required, anywhere in the app.
