1D, 2D and 3D hydraulic modelling of bridges
Modelling bridge crossings in 1D, 2D and 3D: challenges and uncertainties
Flow through and over bridge crossings is a complex affair. Water is forced to: contract and expand due to approach embankments, flow around piers and headstocks, and overtop decks and railings. Emulating this flow, whether in a simple 1D solver or via a complex CFD 3D solution, is challenging with varying degrees of associated uncertainty.
This webinar examines how, as a modeller, bridge crossings are best modelled in 1D, 2D, 3D layered and 3D CFD approaches. The uncertainties associated with each level of modelling and comparisons with measured data and industry guidelines are presented.
