Shuang Gao, one of TUFLOW's leading developers and researchers, published and presented two papers at the (virtual) IAHR ADP Conference hosted from Japan.
The industry leading research and development built into the 2020 TUFLOW release, which has seen the team shortlisted as one of Australia and New Zealand’s most innovative products, was put through its paces as at the IAHR ADP Conference hosted virtually out of Japan where Shuang has had two papers peer reviewed, published and presented during September 2020.
The first paper on high resolution modelling of the Japanese tsunami demonstrates how the new quadtree and Sub-Grid Sampling (SGS) features now make it feasible to use a fixed grid quadtree mesh to model a tsunami from off-shore coarse resolution down to high resolution through the inundated urban areas. SGS plays an important role in removing any grid orientation effects allowing propagation of the wave down narrow streets at any grid orientation.
The second paper presents and extends the significant benchmarking carried out as part of our research and development into the higher order terrain and bathymetry representation produced by SGS with theoretical, flume and real-world benchmark cases presented.
With the Covid-19 situation, the IAHR ADP conference was hosted digitally (Shuang was very disappointed not to make it to Japan :( ). The two papers and pdfs of the presentations are available via our Library Publications and Presentations sections or via the links below:
High Resolution Numerical Modelling of Tsunami Inundation Using Quadtree Method - Paper
Application of Higher Order Bathymetry Representation in Fixed Grid Shallow Water Solvers - Paper
High Resolution Numerical Modelling of Tsunami Inundation Using Quadtree Method - Presentation
Both papers demonstrate the significant amount of innovative research and development, testing and benchmarking that the TUFLOW team have undertaken to provide industry leading hydraulic modelling software.

Off the back of significant research and development as part of the hotly-anticipated 2020 TUFLOW release the TUFLOW team submitted two papers to IAHR's RiverFlow 2020 that were peer-reviewed and accepted for publication.

The Pix Brook Flood Study is a multi-stakeholder options and feasibility investigation needing an integrated catchment wide model. TUFLOW was chosen due to its ability to represent surface water, fluvial and pipe networks within the one modelling software.

The 2020 release of TUFLOW saw a host of exciting and ground-breaking functionality released. Sub-Grid Sampling, and specifically its applications and its benefits, is the focus of this article.

This benchmarking study assesses the performance of TUFLOW 2020 against a dam break test case using data from the Malpasset dam failure in France in 1959. The results show TUFLOW produces an excellent comparison with observed timings and water levels.
