Subjects: Agriculture, Civil and Environmental Engineering, Environmental Engineering

Crop yield and phenological stages are remarkably sensitive to not only environmental factors like atmospheric conditions and physical properties of soils but also agricultural activities. Accurate crop yield prediction plays a crucial role in food security and agricultural sustainability. There are several approaches that a wide range of researchers have tried to predict crop yield at different [...]

Stochastic properties of coastal flooding events -- Part 2: Probabilistic analysis

Byungho Kang, Rusty Feagin, Thomas Huff, et al.

Published: 2023-03-23
Subjects: Civil and Environmental Engineering, Earth Sciences, Engineering

Low-intensity but high-frequency coastal flooding, also known as nuisance flooding, can negatively affect low-lying coastal communities with potentially large socioeconomic effects. This flooding also can greatly affect post-storm coastal dune recovery and reduce the long-term resilience of the back-barrier ecosystem. Recent analytical work has hypothesized that these frequent flooding events are [...]

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

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 [...]

Evidence of Early Supershear Transition in the Feb 6th 2023 Mw 7.8 Kahramanmaraş Turkey Earthquake From Near-Field Records

The Mw7.8 Kahramanmaraş Earthquake was larger and more destructive than what had been expected for the tectonic setting in Southeastern Turkey. By using near-field records we provide evidence for early supershear transition on the splay fault that hosted the nucleation and early propagation of the first rupture that eventually transitioned into the East Anatolian fault. We also find, for the [...]

A two-way coupling 2D-3D hybrid finite element numerical model using overlapping method for tsunami simulation

Guoming Ling, Junichi Matsumoto, Kazuo Kashiyama

Published: 2023-01-13
Subjects: Civil and Environmental Engineering, Engineering

This paper describes a 2D-3D hybrid model for tsunami simulations that uses an overlapping method based on an arbitrary grid. A 2D model is used to simulate wave propagation from the source area to the offshore area, and a 3D model is then used to simulate the free surface flow around structures in coastal areas. An overlapping method that satisfies the conservation and compatibility conditions [...]

MA-SARNet: A One-Shot Forecasting Framework for SAR Image Prediction with Physical Driving Forces

Zhouyayan Li, Zhongrun Xiang, Bekir Zahit Demiray, et al.

Subjects: Civil and Environmental Engineering, Engineering

Remote sensing imagery is one of the most widely used data sources for large-scale earth observations with consistent spatial and temporal quality. However, the current usage scenarios of remote sensing images are largely limited to retrospective tasks as they can only capture existing phenomena. This study proposes MA-SARNet, a one-shot forecasting framework built with a modified MA-Net [...]

Linking thermal and rate behavior with fabric and mineralogy of clayey shear zones: Experimental investigation on the El Forn landslide (Andorra)

Carolina Segui, Esperança Tauler, Tomasz Hueckel, et al.

Subjects: Civil and Environmental Engineering, Engineering, Geotechnical Engineering

Thermal triaxial tests were carried out on remolded material of core samples of the shear zone of a deep-seated landslide, the El Forn landslide (Andorra). With the thermal triaxial tests, we have obtained thermal and rate sensitivi- ties of the material outside and inside the shear band. Moreover, micro-scale tests were carried out, such as XRPD, SEM-EDS, MicroCT, and plasticity index. The [...]

A Web-based Analytical Urban Flood Damage and Loss Estimation Framework

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

Information and communication technology serves a crucial role in communicating flood risk and consequences to a broad range of stakeholders and facilitating mitigation decisions. While studies extensively utilize flood inundation maps for communicating flood risks, there is a need to integrate a broad spectrum of physical vulnerability parameters into risk estimates at various spatial scales. [...]

Laboratory validation of a new hydro-mechanical energy-based brittleness index model for hydraulic fracturing

Brittleness Index (BI) is a critical parameter characterising the deformation regime of geo-materials, covering the range from purely brittle (fractures) to ductile (plastic flow). A variety of BI models have been developed based on rock properties such as mineralogy, elastic parameters, or stress-strain data. However, very few of them are based on the deformation induced by hydro-mechanical [...]

Subjects: Civil and Environmental Engineering, Hydraulic Engineering

Studies of rainfall are usually based on the total amount precipitating throughout a certain period. Compared to rain rates associated with extreme events, the rain rates associated with periods when most of the rainfall occur are not studied extensively. In this study, the characteristics of daily precipitation in India are explored using two metrics - rain frequency peak (the most frequent [...]

The temporal and spatial resolution of rainfall data is crucial for environmental modeling studies in which its variability in space and time is considered as a primary factor. Rainfall products from different remote sensing instruments (e.g., radar, satellite) have different space-time resolutions because of the differences in their sensing capabilities and post-processing methods. In this [...]

During the past few years, Distributing Acoustic Sensing (DAS) has become an invaluable tool for recording high-fidelity seismic wavefields with great spatiotemporal resolutions. However, the considerable amount of data generated during DAS experiments limits their distribution with the broader scientific community. Such a bottleneck inherently slows down the pursuit of new scientific discoveries [...]
