The general intent of these studies is to assess whether or not a slope is considered to be stable and, if not, to provide a “safe” set-back distance from the slope crest behind which structures and other facilities can be constructed. Unstable slopes and the land located between the unstable slope and the set-back line are called “Hazard Lands.” In a broad sense, Hazard Lands are those at risk...

BACKGROUND Duration and speed of propagation of the pulse are essential factors for stability of excitation waves. We explore the propagation of excitation waves resulting from periodic stimulation of an excitable cable to determine the minimal stable pulse duration in a rate-dependent modification of a Chernyak-Starobin-Cohen reaction-diffusion model. RESULTS Various pacing rate dependent fe...

Let rm and rM be the least and greatest finite boundary slopes of a hyperbolic knot K in S . We show that any cyclic surgery slopes of K must lie in the interval (rm − 1/2, rM + 1/2). AMS Classification 57M25; 57M27

Background: Stabilization of unstable slopes with relatively large reinforced concrete piles has been widely adopted over the past several decades. Small diameter steel have advantages as a slope reinforcement technique for an transmission tower where space and access restrictions that typically occur render alternate approaches unfeasible. Methods: In this study, numerical performance assessme...

[1] Mechanistic models for sediment transport on hillslopes are needed for applications ranging from landscape evolution to debris-flow hazards. Progress has been made for soil-mantled landscapes; however, little is known about sediment production and transport in bedrock landscapes that often maintain a patchy soil mantle, even though slopes exceed the angle of repose. Herein we investigate th...

In this paper are treated briefly the geotechnical analysis of hills slopes areas in the heritage town of Berati, Albania. From engineering geological mapping on scale 1:10 000 and geotechnical investigations carried out in urban area of Berati town was found that two zones are threated from landslides phenomenon. The first one is located in center part, whereas the second in northeast part of ...

the soil bioengineering is an applied science that it is the composition of structural, biological and environment concepts for soil erosion, sediment and flood control. biotechnical engineering techniques rely on biological knowledge to build geotechnical and hydraulic structures and to secure unstable slopes and banks. the largest enhancement in development of new soil bioengineering methods ...

Landslides are considered as natural disasters that lead to many deaths and severe property damages worldwide. Therefore, it is necessary to investigate the effective factors in order to make urgent planning and to present management solutions for the sensitive regions. Massive movement of materials, such as a landslide, is one of the problematic hillslope processes in Javanrood located in the ...
