Based on the observation that deposits of large rock avalanches consist predominantly intensely fragmented debris, it is proposed processes fragmentation are significant causes peculiar distribution mass in these deposits, and correspondingly long runout. Rock produces high-velocity fragments moving all directions, resulting an isotropic dispersive stress within translating mass. A longitudinal force consequently acts direction reducing depth tends to cause rear part avalanche decelerate...
Laboratory experiments on granular avalanching of dry sands and gravels reveal a consistent pattern runout distance varying with fall height, slope, volume material for volumes ranging from 0.1 to 1000 L. Data the South Ashburton rock avalanche deposit show that its behaviour differs only slightly laboratory avalanches, extending range this avalanches about 100 000 m 3 . By contrast, data much larger (> 10 7 ) depart significantly trends data; some factor not present in laboratory, such...
Abstract Here we report a laboratory study of the effects debris thickness, diurnally cyclic radiation and rainfall on melt rates beneath rock-avalanche sand (representing typical highly permeable supraglacial debris). Under continuous, steady-state radiation, cover >50 mm thick delays onset ice-surface melting by >12 hours, but subsequent matches bare ice surface. Only when diurnal cycles are imposed does reduce longterm rate it. This is because never reaches heat flux, acquired...
Currently, regional coseismic landslide hazard analyses require comprehensive historical inventories as well detailed geotechnical data. Consequently, such have not been possible where these data are available. A new approach is proposed herein to assess at scale for specific earthquake scenarios in areas without inventories. The model employs fuzzy logic and geographic information systems establish relationships between causative factors slope failures regions with well-documented...
A mass-referenced continuum model for dynamic analysis of rapid mass movement (DAN) is verified by laboratory and field data. Increased earth pressure coefficients are used in this to represent the dispersive pressures caused fragmentation within a translating rock avalanche. The numerical demonstrates that increased runout large avalanches can occur with normal friction if higher than internal pressures, such as those believed be generated fragmentation, present. extent Falling Mountain...
Abstract On 6 October 1999 a very large (c. 10–15 million m3) rock avalanche from Mt Adams blocked the Poerua River 11 km upstream SH6 road bridge on West Coast of South Island. The 120 m high debris dam impounded lake with volume 5–7 m3before it overtopped 7 October. short survival time landslide dams in rivers Westland and around world suggested probability rapid failure flooding downstream. This was confirmed when breached days later 12 1999, during first significant rain after occurred....
Aggradation in the Waiho River has been subject of research for over 40 years (e.g. Mosley, 1983; Hoey, 1990; Davies, 1997; Davies et al., 2003). Where emerges from confinement at Southern Alps rangefront it formed a large alluvial fan. Development on this fan form Franz Josef / Waiau tourist township, State Highway 6 and its bridges, pastoral agriculture resulted artificial active portion fan, principally using stopbanks (flood walls levees). Unable to distribute bedload across surface,...
Landslide dams typically comprise unconsolidated and poorly sorted material are vulnerable to rapid failure breaching, resulting in significant sudden flood risk downstream. Hence they constitute a serious natural hazard, assessment of the likely peak flow rate is required enable preparation adequate mitigation strategies. To determine relative utility accuracy dambreak forecasts, field estimates outflow rates from Poerua landslide dam October 1999 were compared with physical laboratory...
