There are numerous factors that influence hydraulic modelling result accuracy, including: Input data quality, parameter values (e.g. manning’s n), model schematisation, representation of structures and suitability of the computational solver.
Consideration of the each of these factors is essential to building an understanding of the uncertainty associated with hydraulic modelling results. This webinar steps through the fundamental principles that all modellers should be familiar with when developing fit for purpose hydraulic models. A broad range of subjects is covered, from intuitive data related issues through to often misunderstood, or worse yet not considered, consequences of simplifying the computational solution. The webinar finishes with recommendations to maximise the hydraulic model’s accuracy that will meaningfully increase the confidence in models unable to be validated to measured data.
The webinar is strongly recommended for all stakeholders from inexperienced to experienced modellers, from reviewers to end-users of hydraulic modelling outcomes.
Learn about the various aspects of hydraulic model calibration. Verification data types, reliability and quality control, useful model update practices to achieve accurate simulation results and also common result reporting considerations and approaches.
The use of smart particles that dynamically respond to environmental forcing and modify water quality is now possible. Learn how this capability can be exploited to better understand and manage aquaculture operations, and how GPU based computation can accelerate water quality simulation projects.
We discuss the accuracy of direct rainfall modelling based on benchmarking and calibration to historic data sets, and how new features in TUFLOW’s 2020 release have substantially overcome previous shortcomings of 2D hydraulic solvers for rain-on-grid modelling.
One size does not fit all. Hydraulic models need to be designed to suit the site-specific topography, hydrology and also study purpose. Chris Huxley leads this webinar stepping through a best practice workflow to guide your 2D hydraulic model design and build.
Greg Collecutt discusses how new generations of computer hardware favour certain hydraulic solution schemes and offer lower solution costs. Learn how and why current GPU technology can offer significantly lower costs per solution than CPU hardware.
Hear from Bill Syme, the original author of TUFLOW with over 30 years practical experience, as he discusses how new computational methods are increasing simulation speeds and analysis accuracy. Learn of the latest and greatest advancements, and the research that has underpinned TUFLOW’s 2020 release.
All models are wrong to some degree. If so, how wrong is the model and how do we as an industry quantify wrong? Where is the evidence base that a model is right? Watch as Bill Syme draws upon his 30 years experience in applying and developing hydraulic models.
