The construction of a cut-off wall is common reinforcement method for earth rock dams. At present, compared with the in-depth study on homogeneous dams, more and attention being paid to stability deformation dams strengthened by concrete wall. In this study, aiming at Wujing project dam wall, influence water level rise fall slope, body, crack width crest were analyzed numerical calculation in s...

Abstract Reliable assessment of earthen dams’ stability and tailing storage facilities widely used in the mining industry is challenging, particularly under seismic load conditions. In this paper, we propose to take into account effect dominant frequency on tailing/earthen dams. The calculations are performed by finite element modelling (FEM) with Mohr–Coulomb failure criteria. To separate cont...

The objective of this study was to investigate the possibility of a generic rating curve with a small number of adjustable parameters for the restricted class of bedrock step-pool rivers. The motivation for this study arose from Utah Valley University’s long-term program of groundwater development in the Trans-Mexican Volcanic Belt, which requires hydrographs for bedrock step-pool rivers near r...

a new polyvinyl choloride (pvc) membrane sensor for cerium (iii) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22dd) as an ionophore. the sensor exhibites a linear concentration range of 1.0×10-6to 1.0×10-1m, with a nernstian slope of 18.0±1.0 mv/decade, and a detection limit of 9.7×10-7m. it has a fast response time (5 s) and can be used for two mont...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Preferential flow features have been found to be important for runoff generation, solute transport, and slope stability in many areas around the world. Although many studies have identified the particular characteristics of individual feat...

Many slope failures have been observed in deep-cutting gorges Southwest China due to rainfall events. This study conducted model-based tests of the failure a gently dipping accumulation caused by intermittent rainfall. The physical model was established configuring soil samples based on similarity theory and direct shear test data. Intermittent simulated supplying surface runoff bottom pressure...

The effects of lagomorph grazing on the Orthoptera a small hill in Mistley (southeast England) were studied during summer 2020. Transect counts revealed low sward height with abundant bare earth due to high wild rabbit Oryctolagus cuniculus slopes. This intensive led only field grasshopper Chorthippus brunneus (Thunberg, 1815) adults being found any number slopes, perhaps utilizing short swards...

In this paper, model tests on a plain soil slope and bamboo-rooted under top loading were carried out to analyze the surface displacement, change in earth pressure, failure mode of slope. Furthermore, influence rainfall deformation mechanical properties sliding was studied. The results show that: (1) block failure, while progressive backward failure. (2) Under load, displacement shows rule that...

Abstract In the paper numerical modelling of ensuring slope stability and their analysing with using different methods are presented. We have designed cutting walls earth nails anchors securing for ensuring. The calculate mechanism failure process reinforced slopes were studied stability. nailing significantly increased level Spencer method. Increasing nail or length improved slopes. exhibited ...
