Development and validation of an Alaskan coupled storm surge, tide, wind wave, and sea ice forecasting system
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
Published: 2023-06-13
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 [...]
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
Published: 2023-06-06
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 [...]
Listening to Manchester: Using citizen science Raspberry Shake seismometers to quantify road traffic

Subjects: Civil and Environmental Engineering, Earth Sciences, Environmental Public Health, Environmental Sciences, Environmental Studies, Human Geography
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
Published: 2023-05-25
Subjects: Civil and Environmental Engineering
Groundwater overexploitation has been cited as one of the biggest threats to rural drinking water in India, but there is very little quantitative evidence. In this paper, we aim to understand (1) the extent of actual groundwater depletion and its impact on rural drinking water supply systems, (2) the primary driver of groundwater depletion and (3) the additional financial burden in finding new [...]

Subjects: Civil and Environmental Engineering
In recent years, the No. 1 document of the Chinese Party Central Committee has repeatedly mentioned the need to strengthen the agricultural logistics industry and the rapid and healthy development of the cold chain logistics industry, and it is urgent to establish and cultivate some agricultural cold chain logistics enterprises with market competitiveness. In this paper, by considering the green [...]
Mapping Soil Erodibility over India
Published: 2023-04-13
Subjects: Civil and Environmental Engineering, Engineering
Soil erosion is a major environmental problem worldwide, and almost half of India’s total geographical area is susceptible to it. The Revised Universal Soil Loss Equation (RUSLE) has been widely used globally to estimate soil erosion, and Soil erodibility factor, denoted by K-factor, is an essential component of RUSLE. Although previous studies have assessed soil erodibility in India, they have [...]
EfficientRainNet: Smaller Neural Networks Based on EfficientNetV2 for Rainfall Nowcasting
