A Review of Rockfall Mechanics and Modelling Approaches Luuk K.A
Progress in Physical Geography 27,1 (2003) pp. 69–87 A review of rockfall mechanics and modelling approaches Luuk K.A. Dorren Institute for Biodiversity and Ecosystem Dynamics, Universiteit van Amsterdam, Nieuwe Achtergracht 166, NL-1018 WV Amsterdam, the Netherlands Abstract: Models can be useful tools to assess the risk posed by rockfall throughout relatively large mountainous areas (>500km 2), in order to improve protection of endangered residential areas and infrastructure. Therefore the purpose of this study was to summarize existing rockfall models and to propose modifications to make them suitable for predicting rockfall at a regional scale. First, the basic mechanics of rockfall are summarized, including knowledge of the main modes of motion: falling, bouncing and rolling. Secondly, existing models are divided in three groups: (1) empirical models, (2) process-based models and (3) Geophysical Information System (GIS)-based models. For each model type its basic principles and ability to predict rockfall runout zones are summarized. The final part is a discussion of how a model for predicting rockfall runout zones at a regional scale should be developed. AGIS-based distribution model is suggested that combines a detailed process-based model and a GIS. Potential rockfall source areas and falltracks are calculated by the GIS component of the model and the rockfall runout zones are calculated by the process-based component. In addition to this model, methods for the estimation of model parameters values at a regional scale have to be developed. Key words: distributed model, GIS, modelling, natural hazard, rockfall. IIntroduction In mountainous areas rockfall is a daily occurrence. -

Slope Stability and Rock Fall Hazard Assessment of Volcanic Tuffs Using
Slope stability and rock fall hazard assessment of volcanic tuffs using RPAS with 2D FEM slope modelling Ákos Török1, Árpád Barsi2, Gyula Bögöly1, Tamás Lovas2, Árpád Somogyi2, and Péter Görög1 1Department of Engineering Geology and Geotechnics, Budapest University of Technology and Economics, Budapest, H- 5 1111, Hungary 2Department of Photogrammetry and Geoinformatics, Budapest University of Technology and Economics, Budapest, H- 1111, Hungary Correspondence to: Ákos Török ([email protected]) Abstract. Low strength rhyolite tuff forms steep, hardly accessible cliffs in NE Hungary. The slope is affected by rock falls. 10 RPAS (Remotely Piloted Aircraft System) was used to generate a digital terrain model (DTM) for slope stability analysis and rock fall hazard assessment. Cross sections and joint system data was obtained from DTM. Joint and discontinuity system was also verified by field measurements. On site and laboratory tests provided additional engineering geological data for modelling. Stability of cliffs and rock fall hazard were assessed by 2D FEM (Finite Element Method). Global analyses of cross-sections show that weak intercalating tuff layers may serve as potential slip surfaces, however at present the highest 15 hazard is related to planar failure along ENE-WSW joints and to wedge failure. The paper demonstrates that without RPAS no reliable terrain model could be made and it also emphasizes the efficiency of RPAS in rock fall hazard assessment in comparison with other remote sensing techniques such as terrestrial laser scanning (TLS) and tachymetry. 1 Introduction In the past years, technological development of RPAS revolutionized the data gathering of landslide affected areas (Rau et 20 al. -
AND SR 167 - SR 512(PUYALLUP) to I-405 (RENTON) CHARACTERISTICS Segment Description: the SR 167 and SR 512 Highways Function As the Eastern Bypass to I-5
SR 167/SR 512, SR 512- I-5 (LAKEWOOD) TO SR 167 (PUYALLUP) AND SR 167 - SR 512(PUYALLUP) TO I-405 (RENTON) CHARACTERISTICS Segment Description: The SR 167 and SR 512 highways function as the eastern bypass to I-5. These two highways work together in tandem and need to be recognized and evaluated as one corridor. Traveling from south to north, SR 512 begins at I-5, in Lakewood, connecting with SR 167, in Puyallup, continuing north on SR 167 intersecting with I-405 at the north end in Renton. County/Counties: Pierce and King Cities/Towns Included: There are number of cities located along the routes: Lakewood, Puyallup, Sumner, Algona, Pacific, Auburn, Kent and Renton. Number of lanes in the corridor: 1 to 4 Lane width: 12 to 24 feet. Speed limit: 30 to 60 mph. Median width: 0 to 200 feet. Shoulder width: 1 to 22 feet. Highway Characteristics: SR 167 and SR 512 have been designated as both HSS and NHS. SR 167 and SR 512 have been assigned the functional class Urban Principal Arterial. Also, the SR 167 and SR 512 corridor is designated T-1 with annual tonnage up to 43,000,000. Special Use Lane Information (HOV, Bicycle, Climbing): SR 512 has two speed change/weaving lanes. One of the speed change lanes is on the left in the vicinity of ARM 0.27 - 0.63 and the other is on the right in the vicinity of ARM 0.32 - 0.64. There is one climbing lane on SR 512 on the left in the vicinity of 8.85 - 9.79. -

Constructing a spontaneous shrine allows a mourner to create a meaningful narrative ofthe deceased's life, giving structure and significance to a loss that may seem chaotic or meaningless in the immediate aftermath. These vernacular memorials also function as focal points for continued IV communication with the departed and interaction with a community ofmourners that blurs distinctions between public and private spheres.
