Instrumental record of debris flow initiation during natural rainfall: Implications for modeling slope stability
[1] The middle of a hillslope hollow in the Oregon Coast Range failed and mobilized as a debris flow during heavy rainfall in November 1996. Automated pressure transducers recorded high spatial variability of pore water pressure within the area that mobilized as a debris flow, which initiated where local upward flow from bedrock developed into overlying colluvium. Postfailure observations of th...
متن کاملInstrumental Desires , Instrumental Rationality
The requirements of instrumental rationality are often thought to be normative conditions on choice or intention, but this is a mistake. Instrumental rationality is best understood as a requirement of coherence on an agent's non-instrumental desires and means-end beliefs. Since only a subset of an agent's means-end beliefs concern possible actions, the connection with intention is thus more obl...
متن کاملConcrete Debris Recycling, Environmental and Economic Effects
In this paper, first we identify the destruction ways of concrete constructions and the benefits of waste management and the plans to recycle the concrete debris were investigated and it was concluded that the existence of plans to recycle the concrete debris could lead to big economic save ups and by recycling these debris we can create affordable ways for concrete making centers. By the way, ...
متن کاملWoody debris
1. Maximum rate of cut that would provide a hillslope landslide rate of <20% over background, assuming no areas are protected by no-cut buffers .. Summary Downstream impacts to aquatic environments and property generally occur as cumulative watershed impacts, which are usually caused by changes in the transport of woody debris, water, and sediment through a watershed. The downstream cumulative ...
متن کاملMultiple Space Debris Collecting Mission - Debris selection and Trajectory optimization
A possible mean to stabilize the LEO debris population is to remove each year 5 heavy debris like spent satellites or launchers stages from that space region. This paper investigates the ΔV requirement for such a Space Debris Collecting mission. The optimization problem is intrinsically hard since it mixes combinatorial optimization to select the debris among a list of candidates and functional...
