The current study is designed to analyze theslope stability of Haditha damwhich an earth-fill dam constructed on the Euphrates River in middle-west Iraq. Finite element modeling was used present combined seepage and post-earthquake slope earth dam. maximum water level a steady case considered evaluate seepage. - Three different levels (maximum, normal, minimum) were applied, nine equilibrium li...

During the in situ leaching process of ion-adsorption rare earths, solution needs to be constantly injected mine slopes. As a consequence, landslides are highly likely occur due increasing water level soil mass. To solve this problem, we conducted mechanical analysis on rising after injection, which shed light principle slope instability brought about by level. With variation as major factor, e...

The Qinghai–Tibet Plateau (QTP), also known as the Third Pole of Earth, is sensitive to climate change, and it has become a hotspot area for research. As typical natural ecosystem on QTP, alpine wetlands are particularly change. identification different types wetland analysis changes in their distributions areas most direct indicators characterizing impact change wetlands. To understand dynamic...

This paper presents the results of experimental studies on deformation and strength anisotropy gravel-pebble soils used in soil dams. During stabilometric tests, varying shear angles were obtained for stone at different orientations particles working chamber, whether horizontal or vertical. As hydrostatic pressure chamber increased to 0.8 MPa, a reduction by 8-12 degrees depending direction lay...

We survey the progress (or lack thereof!) that has been made on some questions about the p-adic slopes of modular forms that were raised by the first author in [Buz05], discuss strategies for making further progress, and examine other related questions.

16 When increasing the rates of subcritical flow on gentle slopes, the bed successively produces 17 ripples, dunes and flat beds. Antidunes (defined here as all bed undulations for which the 18 surface gravity waves are in phase with the bed profile) appear only in high flow rates and 19 may be found in some extreme natural flow events. Inversely, on steep slopes flume 20 experiment (S≥1% appro...

We study here slopes of periodicity of tilings. A tiling is of slope θ if it is periodic along direction θ but has no other direction of periodicity. We characterize in this paper the set of slopes we can achieve with tilings, and prove they coincide with recursively enumerable sets of rationals.

The Hindu Kush Himalayas (HKH) is a mountain system of extremes with great influence over the Asian continent. The system stretches 3,500 km over eight countries, from Afghanistan in the west to Myanmar in the east. It is the world’s largest and highest mountain system, with more than 30 peaks measuring over 7,600 m. It is also the youngest mountain system on Earth and still tectonically active...

Three-dimensional (3D) limit analysis of stability of slopes is presented. Such analyses are not common because of the difficulties in constructing three-dimensional mechanisms of failure in frictional soils. While examples of 3D translational failure patterns are known, no admissible rotational mechanisms for frictional soils have been described in the literature. A class of admissible rotatio...
