Application of Rapid-Setting Belitic Calcium Sulfoaluminate Cements in Pretensioned, Prestressed Concrete
(2023-05-13)
In recent years, urgency for adopting sustainable materials has come to the forefront of the cement and concrete industries. Belitic calcium sulfoaluminate (BCSA) cement is an alternative cement which has a production ...
A Framework Identifying Impacts of Ensemble Bias Corrected Downscaled Climate Projections on Regional Groundwater Hydrologic Systems in Western Oklahoma
(2023-12-15)
Groundwater is an important natural resource that is highly sensitive to both precipitation and temperature, factors climate models project will change in the future. General circulation models (GCM) are available to ...
Freshwater Stream Monitoring Process Improvements for Fecal Indicator Impairment Designation
(2023-05)
Recreational water quality standards for freshwater streams and rivers are important to understand the potential human health risks associated with primary body contact recreation. Indicator bacteria, Enterococcus and ...
Integrated Hydrologic Validation of Satellite Precipitation over the United States
(2023-12-15)
Increasing precipitation extremes across the globe will naturally lead to not only increased flooding but an increase in the occurrences of flash floods, with assessment and prediction of these events becoming more critical ...
End-Region Evaluation of Hybrid Ultra-High-Performance Concrete/Conventional Concrete Prestressed Girders
(2023-12-15)
In prestressed concrete girders, the end-regions are often susceptible to high internal forces induced by prestressing, resulting in crack propagation. Resisting these forces necessitates a substantial amount of reinforcing ...
Application of Traffic Speed Deflectometer and AI-Based Models for Structural Calibration and Pavement Management Enhancement
(2023)
Currently, different methods are used for the evaluation of pavement conditions including the surface, base, subbase, and subgrade. Among these, Falling Weight Deflectometer (FWD) and/or Fast Falling Weight Deflectometer ...
Performance and environmental impact assessment of agricultural waste-based sorbents for phosphorus recovery and reuse
(2023-05)
Phosphorus is an essential resource, yet global phosphorous reserves are limited, and increasing quantity of high-grade ore is being mined and turned into fertilizers to meet the increasing demand of food. However, since ...
Interpretation of shear wave velocity in unsaturated soils
(2023-12-15)
Shear wave velocity measurements in soil can provide estimates of small strain stiffness and are used for seismic site classification. In comparison to saturated soils, there has been relatively little research on the ...
Using Physicochemical Properties Within a Discrete Element Modeling Framework and Fractal Geometry Theory to Understand Behavior of Unsaturated Expansive Clays
(2023-12-15)
The volumetric deformations associated with expansive soils pose a risk to infrastructure, costing billions in mitigation annually. Many engineering designs assume the soil is in either the dry state or fully saturated. ...
A framework of subseasonal-to-seasonal (S2S) ensemble hydrological forecasting at a watershed scale using dynamical precipitation forecast: forecast verification, adaptation, and streamflow prediction
(2023-12-15)
Accurate and reliable streamflow forecasts, especially at Subseasonal-to-Seasonal (S2S) timescale (spanning 10 to 30 days into the future) could greatly benefit various human socio-economic activities. The Ensemble Streamflow ...
