Abstract. Deep-seated landslides have caused substantial damage to both human life and infrastructure in the past. Developing an early warning system for this type of disaster is crucial reduce its impact on society. This research contributes developing predictive systems deep-seated landslide displacement by employing advanced computational models environmental risk management. The novel framework evaluates machine learning, time series deep convolutional neural networks (CNNs), identifying...
Following the Chi-Chi earthquake in Taiwan, surface soil and rocks were fractured loosened, making geology more unstable. As typhoons continued to batter mountainous regions, resulting heavy rainfall—in terms of total accumulation intensity—exacerbated situation. This caused an increase size collapsed exposed upstream catchment areas, leading damage from rainwater erosion. The migration sand into reservoir, triggering landslides varying scales or other soil-related...
As global warming brings forth extreme precipitation in the typhoon-prone region Asia, e.g. Hong Kong, Taiwan and Japan, need for a scalable yet accurate landslide sensing system becomes increasingly urgent. Natural slopes are focus since their failures often large-scale disastrous; however, it is extremely expensive to monitor every single hazardous natural slope existence with current monitoring system. The MEMS (Micro-Electro-Mechanical Systems) technology which makes miniature sensors...
Water saturation in the bedrock or colluvium is highly related to most landslide hazards, and rainfall likely a crucial factor. The dynamic processes of onsite rock/soil mechanics could be revealed via monitoring using electrical resistivity tomography (ERT) technique Archie’s law. This study aims investigate water changes over time time-lapse ERT images, providing powerful method for events. A fully automatic remote system was deployed acquire hourly data nontraditional hybrid array Lantai...
Sliding Behavior Monitoring of a Deep Seated Landslide with Differential Interferometric Synthetic Aperture Radar, MEMS Tiltmeter and Unmanned Vehicle Images Kuo-Lung Wang, Yo-Ming Hsieh, Jun-Ting Lin Ming-Hsiang Hsi Pages 1045-1051 (2017 Proceedings the 34rd ISARC, Taipei, Taiwan, ISBN 978-80-263-1371-7, ISSN 2413-5844) Abstract: is common issue in Taiwan more than 70% area this island mountainous land. Typhoons earthquakes attack every year even by month. People lost their lives,...
On February 6, 2015, a local magnitude (ML) 6.6 earthquake struck southern Taiwan, devastating the Tainan area. A field investigation was conducted by survey team from National Center for Research on Earthquake Engineering immediately after earthquake. This paper summarizes observed geotechnical damage features caused earthquake, including liquefaction, slope sliding, levee failure, and dam performance. Several liquefaction sites were despite intensity of ground shaking being moderate (peak...
Abstract. In 1996 typhoon Herb struck the central Taiwan area, causing severe debris flow in many subwatersheds of Chen-You-Lan river watershed. More cases occurred following Chi-Chi earthquake, 1999. order to identify potentially affected area and its severity, ability simulate route is desirable. this research numerical simulation deposition process had been carried out using FLO-2D adopting Chui-Sue watershed as study area. Sensitivity parameters used model was conducted adjustments were...
The deep-seated landslide in the Lantai area, Taiwan, has a long history of activity and often damages sole access road to Tai-Ping Mountain National Forest Recreation Area. This study adopted high-resolution digital terrain model (DTMH) derived from UAV mounted LiDAR point cloud data for mapping geological structures verified through field investigation. A slope was proposed with mapped shear zone, numerical analysis conducted using finite difference analysis. failure mechanism found be...
Abstract. Deep-seated landslides, becoming increasingly frequent due to changing climate patterns, pose significant risks human life and infrastructure. This research contributes developing predictive early warning systems for deep-seated slope displacements, employing advanced computational models environmental risk management. Our novel framework integrates machine learning, time series deep convolutional neural networks (CNN), enhanced by the Age of Exploration-Inspired Optimizer (AEIO)...
Vehicular wireless networks (VWNs) offer multi-hop communications between vehicles and roadside units (RSUs). A network with carry-and-forward routing may suffer from longer delay in packet delivery. However, the applications demand stringent requirement VWNs. Therefore, this paper proposes an adaptive RSU re-routing strategy to alter current associated best under or throughput constraints for Performance results show that proposed is able adaptively select a suitable size trade-off satisfy...
The area of Taiwan is 70% hillsides. In addition, the topography fluctuates wildly, and it active in earthquakes young orogenic movements. Landslides are a widespread disaster Taiwan. However, landslides not until someone enters mountain for development. Therefore, landslide displacement monitoring primary task this study. Potential areas with mostly slate geological conditions were selected as candidate sites bedding approximately 30 to 75 degrees toward southeast, which means that creep...
