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.

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 [...]

A recent trend in hydroinformatics has been the growing number of data, models, and cyber tools which are web accessible, each aiming to improve common research tasks in hydrology through web technologies. Coupling web-based models and tools holds great promise for an integrated environment that can facilitate community participation, collaboration, and scientific replication. There are many [...]

The Asymmetric Distribution of Rainfall Frequency and Amounts in India

Yash Gupta, Manabendra Saharia, Bhupendranath Goswami

Published: 2022-09-29
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 [...]

A Systematic Review of Deep Learning Applications in Streamflow Data Augmentation and Forecasting

The volume and variety of Earth data have increased as a result of growing attention to climate change and, subsequently, the availability of large-scale sensor networks and remote sensing instruments. This data has been an important resource for data-driven studies to generate practical knowledge and services, support environmental modeling and forecasting needs, and transform climate and earth [...]

TempNet – Temporal Super Resolution of Radar Rainfall Products with Residual CNNs

Muhammed Sit, Bong-Chul Seo, Ibrahim Demir

Published: 2022-09-22
Subjects: Civil and Environmental Engineering, Engineering

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 [...]

python-ags4: A Python library to read, write, and validate AGS4 geodata files

Asitha Senanayake, Roger Chandler, Tony Daly, et al.

Subjects: Civil and Environmental Engineering, Earth Sciences, Engineering, Environmental Engineering, Geochemistry, Geology, Geophysics and Seismology, Geotechnical Engineering

Data gathered from geotechnical, geoenvironmental, and geophysical investigations can be broadly described as "geodata". The AGS4 data format is one of the most widely used data transmittal formats for geodata and is used across the world. It is a plain text format consisting of multiple tables of comma-separated values, tied together with a robust data schema and a comprehensive suite of [...]

PubDAS: a PUBlic Distributed Acoustic Sensing datasets repository for geosciences

Zack J. Spica, Jonathan Ajo-Franklin, Greg Beroza, et al.

Published: 2022-09-07
Subjects: Civil and Environmental Engineering, Earth Sciences, Environmental Sciences, Oceanography and Atmospheric Sciences and Meteorology

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 [...]

HydroLang Markup Language: Community-Driven Web Components for Hydrological Analyses

Carlos Valentin Erazo, Muhammed Yusuf Sermet, Ibrahim Demir

Published: 2022-08-25
Subjects: Civil and Environmental Engineering, Computational Engineering, Environmental Engineering, Science and Mathematics Education

We introduce HydroLang Markup Language (HL-ML), a programming interface that uses markup language to perform environmental analyses using the hydrological and environmental framework HydroLang. The software acts as a self-contained interface that uses HTML tags powered by the web components specification to generate simple hydrological computations that enable data analysis, visualization and [...]

Floods affect over 2.2 billion people worldwide, and their frequency is increasing at an alarming rate compared to other natural disasters. Presidential disaster declarations have issued increasingly almost every year in Iowa for the past 30 years, indicating that the state is on the rise of flood risk. While significant scientific and technological advancement is becoming available for many [...]

A Generalized Natural Hazard Risk Modelling Framework for Infrastructure Failure Cascades

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

Critical infrastructures are more exposed than ever to natural hazards in a changing climate. To understand and manage risk, failure cascades across large, real-world infrastructure networks, and their impact on people, must be captured. Bridging established methods in both infrastructure and risk modelling communities, we develop an open-source modelling framework which integrates a [...]

Defining renewable groundwater use to improve groundwater management

Subjects: Civil and Environmental Engineering, Earth Sciences, Engineering, Environmental Sciences, Physical Sciences and Mathematics

Groundwater systems are commonly but variously defined as renewable or non-renewable based on natural fluxes of recharge or on estimates of aquifer storage and groundwater residence time. However, the principle of capture challenges simple definitions: groundwater pumping can alter the rates of groundwater recharge and/or discharge over a characteristic groundwater response time related to the [...]
