We develop a process-based model to simulate the geomorphodynamic evolution of tidal channels, considering hydrodynamics, flow-induced bank erosion, gravity-induced bank collapse, and sediment dynamics. A stress-deformation ...

The occurrence of collapsible soils and collapse processes due to disruptions in water and sewage networks is the main urban environmental problem concerning material losses in many cities of southeastern Brazil. This work ...

Soil collapse is a major geotechnical problem that causes architectural and structural damage to buildings and engineering infrastructure. Losses due to soil collapsibility have an economical aspect and the study of these ...

The paper revisits and updates two expedite methods used to identify the occurrence of collapsible soils. The methods were proposed by Gibbs (1961) and de Mello (1973) and have in common the assumption that collapsible ...

Collapsible soils are unusual geomaterials found in several regions of the world. These soils undergo sudden and large volumetric compressive deformations upon wetting under constant loading. It is a problematic soil that ...

A typical residual clayey soil originating from basalt in southern Brazil has been analyzed in order to assess the influence of wetting-induced deformation and microstructural features on the collapse behavior. Single and ...

We introduce the theory of strong homotopy types of simplicial complexes. Similarly to classical simple homotopy theory, the strong homotopy types can be described by elementary moves. An elementary move in this setting ...

The term collapsibility of soils is not always understood, since engineering projects rarely take into account the effects caused by the phenomenon, which is responsible for several problems in earthmoving services, channels, ...
