Following spatially expansive landslide events, rapid remote sensing data acquisition is perhaps the most efficient means of capturing nature and extent landsliding. This particularly true in Appalachian Mountains eastern North America, where high annual rainfall, humidity, vegetation can obscure features within a single growing season. In July 2022, convective rainfall event with an exceedance probability 0.1–0.2% caused record-breaking flooding widespread landslides throughout...
Rockfall is a frequent hazard in mountainous areas, but risks can be mitigated by the construction of protection structures and slope modification. In this study, two rock slopes along highway western Colorado were monitored monthly using Terrestrial Laser Scanning (TLS) before, during, after mitigation activities performed to observe influence weather variables on rockfall activity. Between September 2020 February 2021, mechanically scaled reinforced bolts, wire mesh, polyurethane resin...
Building historical geographic information system (HGIS) datasets is time consuming and very expensive, especially when built at the scales that permit analysis of lived experiences individuals or morphology buildings streets. Further, these are often exclusively in academy, with little input from contemporary communities they represent. In this paper, we review use public crowdsourcing data creation, using Keweenaw Time Traveler set Michigan's Copper Country as a case study, call for new...
Rockfall processes are now commonly studied through monitoring campaigns using repeat lidar scanning. Accordingly, several recent studies have evaluated how the temporal resolution of data collection and various data-processing decisions can influence apparent rockfall volumes estimated typical database creation workflows. However, there is a lack that consider quality associated volume estimation. In this work, we perform series tests based on an existing reference from Front Range...
The occurrence or reactivation and acceleration of landslides can occur unannounced result in significant impacts to life, property, the environment. processes slope deformation progressive failure are more active than many realize; rapid failures often preceded by years erosion, deformation, smaller failures. In last 10 years, use lidar-derived elevation models has supported identification across large regions is increasing ability geoprofessionals identify precursory signs During same time...
Automatically identifying mine and tunnel infrastructure elements, such as rock bolts, from point cloud data improves deformation quality control analyses could ultimately contribute to improved safety on engineering projects. However, we hypothesize that existing methods are sensitive small changes in object characteristics across datasets if trained insufficiently, previous studies have only investigated single datasets. In this study, present a cross-site training (generalization)...
ABSTRACT: Hydraulic plucking of rock blocks bounded by discontinuities is one the primary modes scour in unlined spillways. The methods used current state-of-practice either model a single block considerable detail or introduce many simplifications to reduce runtime and complexity. We present method for simulating at spillway scale using an open-source discrete fracture network slicing program coupled with FLOW-3D. built custom implementation limit equilibrium theory this task which enables...
Topographic change detection is increasingly being used to identify and monitor landslides other geohazards in support of risk-informed decision-making. Expanding from site specific regional scales enables proactive asset management contributes improving the resilience infrastructure extreme events. It widely known that precision can be improved by applying three-dimensional algorithms, such as iterative closest point (ICP) M3C2, directly raw clouds. However, this also increases...
Managing geotechnical hazards requires geo-professionals to understand how the earth may behave into future. Understanding morphological change involves a deep understanding of geology, geological processes, climate change, and knowledge physical changes that have happened in past or occur One most capable techniques for mapping changing terrain across spatially extensive regions is lidar detection using airborne scanning (ALS) data. Change commonly performed DEM differencing (DoD), but this...
