3D mats are environmentally friendly and ecological materials for protecting river waterway banks. The anti-scour properties of the erosion resistance soil under them can be studied to provide decision support selection slope protection their applicable areas. In this paper, an indoor prototypical scouring experiment with a flume is carried out study three types mat (vegetation grass mats, Enka...

To date, a plethora of electrocatalysts for the Oxygen Evolution Reaction (OER) have been proposed. For evaluating their electrocatalytic behavior determination onset potential in each studied electrolyte is key parameter. Nevertheless, this evaluation becomes particularly problematic first-transition metal catalysts as well by use electroactive collectors (e.g. Ni foams) whose redox peaks over...

The design of dams requires comprehensive studies to ensure the safety and feasibility these important engineering projects, as any possible failure case may lead considerable losses in human life properties. Specifically, analyses should be performed evaluate seepage, slope stability, soil liquefaction large earth dams. In this study, numerical modeling, based on finite element methods, was us...

the behavior of earth dams has particular complexities against dynamic forces and its assessment requiresdetailed and scientific analysis. the farrokhi earth dam is a heterogeneous type with vertical clay core, built 150 km away from birjand and 41 km away from qaen on the farrokhi river. there are concernsregarding the stability of this dam in the event of a future severe earthquake especially...

inclined retaining walls with slopes less than perpendicular are appropriate candidates in several engineering problems. yet, to the knowledge of authors, only a few analytical solution for calculation of active earth pressure on such walls, which will be usually smaller than the same pressure on vertical ones, has been presented neither in research papers nor in design codes. considering limit...
