The paper deals with the assessment of the rockfall risk for a road stretch, in southern Italy, affected by high traffic intensity. Three qualitative rockfall risk rating systems (QRSs) which use an exponential scoring with a base of 3 were employed, and then ...

<p>This report gives an overview of the issues that need to be considered in completing a risk-based approach to the management of slope instability hazards in the Port Hills. A framework and process for managing risk is described, international and New Zealand ...

<p>Despite some preliminary developments for Slope Management Systems (SMS) for the South African Road Network, no functional SMS has been implemented. Slopes along important strategic routes are generally not monitored and only maintained on a reactive basis. ...

The highway between Aswan and Cairo on the eastern bank of the Nile Valley is one of the most used highways in Egypt, connecting most of the governorates with each other. It represents the backbone of Egyptian transportation and commercial traffic. This Highway ...

The results of a series of physical model studies of the stability of jointed rock slopes carried out some years ago are described in this paper.

<p>Based on the assumption that major class of rock instabilities are created by discontinuities, a method is proposed to estimate the fracture density by means of a digital elevation model (DEM). By using the mean orientation, the mean spacing and the mean ...

<p>The need for monitoring slope movements increases with the increasing need for new areas to inhabit and new land management requirements. Rock-slope monitoring implies the use of a database, but also the use of other tools to facilitate the analysis of ...

A posteriori studies of rock slope instabilities generally show that rockfalls do not occur at random locations: the failure zone can be classified as sensitive from geomorphological evidence. Zones susceptible to failure can therefore be detected. Effects ...

In December 1963 rockfalls from Little Tahoma Peak on the east side of Mount Rainier volcano fell onto Einmons Glacier and formed avalanches of rock debris that traveled about 4 miles down the glacier and the White River valley. In this distance, the rock ...
