Formal Processes for Inspecting Bridge Deck Drains Using Lidar and Photogrammetry
(2023-05-08)**Please note that the full text is embargoed until 05/04/2025** ABSTRACT: Poor-performing bridge deck drains result in water standing on the bridge deck. The standing water threatens the safety of bridge users and ... -
Framework for Determining the Pullout Resistance of Inextensible 2-Wire Soil-Reinforcing Elements Embedded in Sand
(2018-10-04)Mechanically Stabilized Earth (MSE) has been successfully used as a commercial retaining structure since its development in 1963 by Henry Vidal (Schlosser 1990). MSE is a ground improvement system that consists of ... -
Geohazard Potential Of Rainfall Induced Slope Failure On Expansive Clay
(Civil & Environmental Engineering, 2013-03-20)Each year, rain induced slope failures cause significant damages in highway infrastructures and environments, as well as tragic losses of human lives around the world. Rainfall-induced slope failure is a common problem in ... -
Group Assignment and Annual Average Daily Traffic Estimation of Short-term Traffic Counts Using Gaussian Mixture Modeling and Neural Network Models
(2016-09-13)The grouping of similar traffic patterns and cluster assignment process represent the most critical steps in AADT estimation from short-term traffic counts. Incorrect grouping and assignment often become a significant ... -
HARMFUL ALGAL BLOOMS AND BIOLOGICAL TOXINS PRODUCTIONS; FROM INTEGRATED MONITORING APPROACH TO ON-SITE SOLAR PHOTOCATALYTIC DECOMPOSITION
(2016-12-20)Occurrence of Harmful Algal Blooms (HABs) worldwide has caused concern to environmental and health authorities because of their potential to generate and release biological toxins. In particular, microcystins (MCs) produced ... -
HPFRC and RC Slab-Beam-Column Connections under Extreme Earthquake Loading and Further Improvement of Novel Double-Beam-Coupling Beams
(2018-12-10)The work presented in this dissertation is divided into two parts. Each part has drawn its own results. Reinforced concrete (RC) buildings resist a strong earthquake through structural foundations, diaphragms, and ... -
Hydraulic Performance Evaluation Of Different Recirculation Systems For ELR / bioreactor Landfills
(Civil & Environmental Engineering, 2013-07-22)The major aspect of bioreactor landfill is the addition of liquid and recirculation of collected leachate back into the waste mass through the subsurface Leachate Recirculation System (LRS). The leachate recirculation ... -
Hydraulic Performance Evaluation of Evapotranspiration Cover Systems
(2016-12-07)Although alternative covers such as the evapotranspiration (ET) landfill cover system promise to provide equivalent or greater performance than conventional cover systems, uncertainties remain on the performance of these ... -
