sediment transport in rivers and torrents efficiently. <strong>Physical hydraulic models<\/strong> are used to test a very wide range of technical solutions and explore extreme scenarios without risk. They are also highly efficient communication and consultation tools\u00a0for assisting decision-makers when making technical-economic choices.<\/p>\n<p>Despite the increase in the technical capacities of mathematical modelling, <strong>physical hydraulic models <\/strong>remain indispensable tools when designing a hydraulic development in which complex flows occur or which may have an impact on hydrodynamics and sediments difficult to foresee in the long-term.<\/p>\n<p>Far from being antagonistic, <strong>physical hydraulic<\/strong> and numerical models are now used in complete synergy and are well-adapted for joint use when simulating the most difficult hydro-sedimentary problems.
