Autor: Říha Jaromír, Duchan David, Zachoval Zbyněk, Erpicum Sébastien, Archambeau Pierre, Pirotton Michel, Dewals Benjamin

Publikováno v: Journal of Hydrology and Hydromechanics, Vol 67, Iss 4, Pp 322-328 (2019)

Shallow-water models are standard for simulating flow in river systems during floods, including in the near-field of sudden changes in the topography, where vertical flow contraction occurs such as in case of channel overbanking, side spillways or le

Improvement of anisotropic porosity models with a merging technique

Autor: Bruwier Martin, Archambeau Pierre, Erpicum Sébastien, Pirotton Michel, Dewals Benjamin

Publikováno v: E3S Web of Conferences, Vol 40, p 06023 (2018)

Anisotropic porosity shallow-water models are used to take into account detailed topographic information through porosity parameters multiplying the various terms of the shallow-water equations. A storage porosity is assigned to each cell to reflect

Unsteady shallow meandering flows in rectangular reservoirs: A modal analysis of URANS modelling

Autor: Valero, Daniel, Bung, Daniel B., Erpicum, Sebastien, Peltier, Yann, Dewals, Benjamin

Publikováno v: Journal of Hydro-environment Research, 42, 12-20 (2022)

Shallow flows are common in natural and human-made environments. Even for simple rectangular shallow reservoirs, recent laboratory experiments show that the developing flow fields are particularly complex, involving large-scale turbulent structures.
