Abstract. The Jinsha River, which has carved a 2–4 km deep gorge, is one of the largest SE Asian rivers. Two successive landslide-lake outburst floods (LLFs) occurred after 2018 Baige landslides along river. Using Sentinel-2 images, we examined LLF impacts on downstream river channels and adjacent hillslopes over 100 distance. increased width active channel by 54 %. Subsequently, major persiste...

in the mind, language and literature of all people, there are some significant numbers like three, thirty, six, nine, twelve, forty, one hundred and one thousand that are called numbers of perfection. sometimes one digit is added to these numbers (and the result is seven, thirteen, ten and one thousand and one) or is subtracted from them (and the result is five, ninety nine or eleven) and the o...

in this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in euler-bernoulli beams are assessed. static response of a beam is obtained using the finite element modeling. in order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...

residential mobility is an important ecological mobility which, besides physical impacts, has contributed in shaping or reshaping of urban social milieus. the analyses of results related to a sample of 17510 households inhabiting in 40 regions of mashhad indicates that 46.9 percent of them had experienced a residential relocation during a period of ten years, the maximum of which (62.8 percent)...

The ancient levees used for flood control generally exist in the rainy areas of southern China. After years operation, have lots problems, such as leakage, swelling, and cracking, which need to be reinforced. In this paper, combined with characteristics river water level fluctuations, effect upside-down hanging well curtain grouting reinforcement levee is analyzed by a numerical method, variati...

The lattice location of copper in single-crystalline zinc oxide was studied by means of the emission channeling technique. Following 60-keV room-temperature implantation at a fluence of 2.3310 cm, the angular distribution of b particles emitted by the radioactive isotope Cu was measured by a position-sensitive detector. The b emission patterns give direct evidence that in the as-implanted state...

We present the initial results of rapid fault estimations for the 2016 Kumamoto earthquake on April 16 (Mj 7.3), and coseismic displacements caused by the two large foreshocks that occurred on April 14 (Mj 6.5) and April 15 (Mj 6.4) from the GEONET real-time analysis system (REGARD), which is based on a Global Navigation Satellite System (GNSS) kinematic positioning technique. The real-time fin...

Assessment of geological hazards in urban areas must integrate geospatial and temporal data, such as complex geology, highly irregular ground surface, fluctuations in pore-water pressure, surface displacements and environmental factors. Site investigation for geological hazard studies frequently produces surface maps, geological information from borehole data, laboratory test results and monito...
