Subjects: Civil Engineering, Environmental Engineering, Environmental Sciences, Risk Analysis

Natural hazards impact the interdependent infrastructure networks that keep modern society functional. While a variety of critical infrastructure network (CIN) modelling approaches are available to represent CI networks on different scales and analyse the impacts of natural hazards, a recurring challenge for all modelling approaches is the availability and accessibility of sufficiently [...]

Yield strength determination based on dissipative energetic transition

Published: 2023-08-30
Subjects: Applied Mechanics, Civil Engineering, Earth Sciences

Mechanical yield strength is one of the most crucial mechanical properties to consider to remain operating in safe elastic regimes. Despite its importance, it remains ambiguous to measure as different disciplines acknowledge different definitions. Most common examples include the deviation from linear elasticity or the peak stress. This difference has significant consequences for the modelling of [...]

Subjects: Civil and Environmental Engineering, Civil Engineering, Hydraulic Engineering

Remote sensing (RS) imagery is becoming increasingly popular in surface water extent extraction thanks to the increasing availability of RS data and advancements in image processing algorithms, software, and hardware. Many studies proved that RS imagery can work independently or along with other approaches to identify flood extent. However, due to the insufficiency in the number of images from [...]

Better Localized Predictions with Out-of-Scope Information and Explainable AI: One-Shot SAR Backscatter Nowcast Framework with Data from Neighboring Region

Synthetic Aperture Radar (SAR) provides 10-m weather-independent global Earth surface observations for various tasks such as land cover land use mapping, water body delineation, and vegetation change monitoring. However, the application of SAR imagery has been limited to retrospective tasks by a “first event then observation” rule. Recent studies have proven the feasibility of a one-shot forecast [...]

Non-structural Flood Mitigation Optimization at Community Scale: Middle Cedar Case Study

Subjects: Civil and Environmental Engineering, Civil Engineering, Engineering, Environmental Engineering, Risk Analysis

Flooding is the leading natural hazard in Iowa and has resulted in billions of dollars of damage to properties and critical infrastructure over the past couple of decades. Land alterations, urbanization, and changing precipitation regimes increase the magnitude and frequency of flood events. Considering the increasing risk, flood mitigation efforts are significant to reduce future losses. In this [...]

Geo-Spatial Analysis of Built-Environment Exposure to Flooding: Iowa Case Study

Yazeed Alabbad, Ibrahim Demir

Published: 2023-03-15
Subjects: Civil and Environmental Engineering, Civil Engineering, Engineering, Risk Analysis

Flooding is the most frequent type of natural disaster, inducing devastating damages at large and small spatial scales. Flood exposure analysis is a critical part of flood risk assessment. While most studies analyze the exposure elements separately, it is crucial to perform a multi-parameter exposure analysis and consider different types of flood zones to gain a comprehensive understanding of the [...]

Time Series Analysis of terrain and climatic parameters data retrieved from Terraclimate dataset: A case study in Ranchi and Khunti district, Jharkhand, India

Subjects: Civil Engineering, Engineering, Other Civil and Environmental Engineering

Climatic and Terrain parameters which include the soil moisture, precipitation, evapotranspiration, maximum and minimum temperature are the most crucial factors which drives the future of earth. Soil Moisture regulates the movement of water and heat energy between the land surface and the atmosphere through evaporationn and plant transpiration. Precipitation controls the entire operation of the [...]

Rapid seaward expansion of seaport footprints worldwide

Subjects: Civil Engineering, Geographic Information Sciences, Geomorphology, Other Environmental Sciences, Physical and Environmental Geography, Remote Sensing, Sustainability

As global maritime traffic increases, seaports grow to accommodate and compete for higher volumes of trade throughput. However, growth trajectories of seaport footprints around the world have gone unmeasured, likely because of a lack of readily available spatio-temporal data. Here, we use geospatial analysis of global satellite imagery from 1990–2020 to show that 65 seaports among the world's top [...]

The 2015 Mw 7.8 Gorkha, Nepal earthquake is the largest event to have struck the capital city of Kathmandu in recent times. One of its surprising features was the frequency content of the recorded ground motion, exhibiting a notable amplification at low frequencies (< 2 Hz) and a contrasting depletion at higher frequencies. The latter has been partially attributed to the damper behaviour of the [...]
