A rockfall protection embankment is an earthwork built in elevation with respect to the ground to intercept falling rock fragments before elements at risk such as roads and buildings are reached. This term is widely used in the rockfall community but the terms bunds and walls are sometimes used as alternatives.
Rockfall in Utah, USA. Favourable geology and climate are the principal causal mechanisms of rockfall, factors that include intact condition of the rock mass, discontinuities within the rockmass, weathering susceptibility, ground and surface water, freeze-thaw, root-wedging, and external stresses. A tree may be blown by the wind, and this ...
A rockfall barrier is a structure built to intercept rockfall, most often made from metallic components and consisting of an interception structure hanged on post-supported cables. [ 1 ] Barriers are passive rockfall mitigation structures adapted for rock block kinetic energies up to 8 megajoules.
The Watershed and Flood Prevention Operations Program, a program of the Natural Resources Conservation Service (NRCS), includes Watershed Operations (under the Flood Control Act of 1944, P.L. 78- watershed projects to distinguish them from larger downstream projects built by the U.S. Army Corps of Engineers and by the Bureau of Reclamation.
The output of the analysis is a factor of safety, defined as the ratio of the shear strength (or, alternatively, an equivalent measure of shear resistance or capacity) to the shear stress (or other equivalent measure) required for equilibrium. If the value of factor of safety is less than 1.0, the slope is unstable.
Many fire departments have fire prevention divisions, which consist of groups of firefighters who conduct building inspections to make sure they are compliant with fire codes; they also visit schools and daycare centers to make presentations about arson, malicious false alarms, and fire safety. Fire Prevention Officers may also conduct tours of ...
Fire prevention programs; Fire dynamics and fire modeling; Human behavior during fire events; Risk analysis, including economic factors; Wildfire management [1] Fire protection engineers identify risks and design safeguards that aid in preventing, controlling, and mitigating the effects of fires.
Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires. [1] [2] It involves the study of the behaviour, compartmentalisation, suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems.
