2d river flood modelling using Hec-ras 5.0
(Universitat Politècnica de Catalunya, 2016-06-20)
Bachelor thesis
Open AccessFlooding may occur as an overflow of water from water bodies, such as a river, lake or ocean, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries. Floods also occur ... -
3D Hydrodynamical simulations of helium-ignited double-degenerate white dwarf mergers
(2022-06-01)
Article
Open AccessThe origins of Type Ia supernovae (SNe Ia) are still debated. Some of the leading scenarios involve a double detonation in double white dwarf (WD) systems. In these scenarios, helium shell detonation occurs on top of a ... -

Article
Open AccessIn this work a finite element method is proposed to solve the problem of estimating the added resistance of a ship in waves in the time domain and using unstructured meshes. Two different schemes are used to integrate the ... -
A numerical study on hydraulic fracturing problems via the proper generalized decomposition method
(2020-02-01)
Article
Open AccessThe hydraulic fracturing is a nonlinear, fluid-solid coupling and transient problem, in most cases it is always time-consuming to simulate this process numerically. In recent years, although many numerical methods were ... -
A review of flood impact assessment approaches for underground infrastructures in urban areas: a focus on transport systems
(2020-06)
Article
Open AccessFlooding events can produce significant disturbances in underground transport systems within urban areas and lead to economic and socioenvironmental well-known consequences, which can be worsened by variations in the ... -
