Webinar: Too hard for Einstein! Sediment transport and mobile bed hydraulics

Where are we now? Are we proving Einstein wrong?

When Albert Einstein’s oldest son, Hans, told his father he wished to pursue sediment transport as a career – so the story goes – Albert reportedly said, “No, that’s much too difficult!” So where are we now? Have advances in software and computational power finally granted us the ability to prove Einstein wrong?

Eroding rivers and sediment-filled reservoirs pose an increasing threat to lives, environment, and infrastructure around the world. Please join us for this engaging, interactive webinar in which we’ll cover the challenges and opportunities associated with mobile-bed hydraulic modelling, which has the potential to allow the prediction and mitigation of impacts associated with sediment movement.

In this webinar we will provide an overview of sediment transport modelling software options, along with requirements for the collection of input data, selection of modelling parameters, and calibration techniques. We’ll also discuss the trade-offs between qualitative geo-morphological assessments and quantitative numerical modelling, followed by a demonstration of sediment transport capabilities using the U.S. Army Corps of Engineers’ HEC-RAS program.

The key take-home messages for this webinar are:
1. Krey: (5 min) Introduction and typical applications suited for sediment transport modelling.
2. Marty: (10 min) Sediment transport model input data requirements, overview of software options, and requirements for calibration.
3. Stanford: (15 min) HEC-RAS model conceptual background, limitations, and demonstration of capabilities.
