Continental scale hydrostratigraphy: comparing geologically informed data products to analytical solutions

Jackson Swilley, Danielle Tijerina-Kreuzer, Hoang Tran, et al.

Published: 2023-09-12
Subjects: Civil and Environmental Engineering, Geology, Hydrology

This study synthesizes two different methods for estimating hydraulic conductivity (K) at large scales. We derive analytical approaches that estimate K and apply them to the contiguous US. We then compare these analytical approaches to three-dimensional, national gridded K data products and three transmissivity (T) data products developed from publicly available sources. We evaluate these data [...]

Floods and droughts significantly affect agricultural activities and pose a threat to food security by subsequently reducing agricultural production. The impact of flood events is distributed disproportionately among agricultural communities based on their socio-economic fabric. Understanding climate-related hazards is critical for planning mitigation measures to secure vulnerable communities. [...]

Satellite remote sensing is becoming a widely used monitoring technique in coastal sciences. Yet, no benchmarking studies exist that compare the performance of popular satellite-derived shoreline (SDS) mapping algorithms against standardized sets of inputs and validation data. Here we present a new benchmarking framework to evaluate the accuracy of shoreline change observations extracted from [...]

Assessing Precipitation Trends that may inform Aging Dam Overtopping across the USA

Jeongwoo Hwang, Upmanu Lall

Published: 2023-07-07
Subjects: Civil and Environmental Engineering, Climate, Earth Sciences, Hydrology, Risk Analysis

In many cases, persistent or recurrent synoptic circulation patterns lead to multiple wet days that precede an extreme rainfall event. The joint occurrence of high antecedent rainfall and extreme rainfall defines a compound event that may pose a high risk for overtopping of aging dams. Our novel analysis assesses whether there are significant trends across the conterminous United States (CONUS) [...]

Can crop production intensification through irrigation be sustainable? An ex-ante impact study of the coastal zone of Bangladesh

Zahirul Haque Khan, Md Saiful Islam, Shume Akhter, et al.

Subjects: Civil and Environmental Engineering

In Bangladesh’s south-central coastal zone, there is considerable potential to intensify crop production by growing dry winter season ‘Boro’ rice, maize, wheat, pulses and oilseeds using irrigation from southward flowing and predominantly freshwater rivers. However, the impacts of surface water withdrawal for irrigation and its safe operating space remain unclear. We used field measurements and [...]

Development and validation of an Alaskan coupled storm surge, tide, wind wave, and sea ice forecasting system

Guoming Ling, Damrongsak Wirasaet, Joannes Westerink, et al.

Published: 2023-06-16
Subjects: Civil and Environmental Engineering

Western Alaska regularly experiences storm surge events induced by extra-tropical storms, most active during fall, winter, and spring. Among others, the presence of sea ice in Western Alaska seawater poses a challenge in modeling storm surge in this area. Existing storm surge models rarely consider sea ice effects together with wind-induced wave effects. In this paper, we present an ALaska [...]

Flood Sequence Mapping with Multimodal Remote Sensing Under the Influence of Dense Vegetation: Mississippi River Case Study

Zhouyayan Li, Ibrahim Demir

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

Remote sensing (RS) imagery has become more and more popular in surface water extent extraction applications with the help of increasing availability of RS data and advancements in image processing algorithms, software, and hardware. Many studies have demonstrated that RS imagery has the potential to work independently or along with other well-documented approaches in identifying flood extent. [...]

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 [...]

Ensemble modeling of the two-dimensional stochastic confined groundwater flow through the evolution of the hydraulic head's probability density function

Joaquin Meza, M Levent Kavvas

Published: 2023-06-05
Subjects: Civil and Environmental Engineering

Groundwater storage in aquifers has become a vital water source due to water scarcity in recent years. However, aquifer systems are full of uncertainties, which inevitably propagate throughout the modeling computations, mainly reducing the reliability of the model output. This study develops a novel two-dimensional stochastic confined groundwater flow model. The proposed model is developed by [...]

Road traffic is a major contributor to greenhouse gases in our cities. This study has been designed to test whether low-cost citizen science seismometers (Raspberry Shakes) can be used to quantify temporal and spatial variations in road traffic. I used a network of seismometers installed around Greater Manchester to record signals in the frequency range 1-50 Hz. Data were processed using the open [...]

Chasing the water table: The impact of groundwater depletion on rural drinking water supply in peninsular India
