Abstract: This paper presents the application of a nonoscillatory second order relaxation scheme to simulation of flow in open channel networks. The approach is based on the Saint Venant equations written in conservative form. ...

Abstract: Carbon nanotubes (CNTs) can be used as atomic force microscope (AFM) probes due to their robust mechanical properties, high aspect ratio and small diameter. In this study, a model of CNTs clamped in an elastic medium is ...

Abstract: Anaerobic–aerobic hybrid bioreactor landfills, operated in a specific way that combines the benefits afforded by both anaerobic and aerobic processes, can significantly enhance the degradation of municipal solid waste (MSW) ...

Abstract: Leachate recirculation in municipal solid waste (MSW) landfills operated as bioreactors offers significant economic and environmental benefits. However, vertical well (VW) recirculation may not be an effective method because ...

Abstract: Horizontal drains can effectively accelerate the consolidation of soils. In this study, an analytical model for the consolidation of a multilayered soil system with horizontal drainage pipes is developed first. A virtual ...

Abstract: The moving water table would vary soil layering and may significantly affect the isolation efficiency of wave barriers. A two-dimensional finite-element model is then developed using COMSOL to study the influence of the ...

Abstract: Flowslides are rapid gravity-driven flows of sediment-water mixture that typically occur following slope failures in soils, tailings, and municipal solid wastes, but the progressive state transition during the evolution ...

Abstract: The dynamic compaction (DC) method is a versatile ground treatment technique with growing popularity. It is applicable to a wide variety of soil types and conditions, particularly sandy materials and granular fills. This ...
