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 ... -
HYDROCARBON POOL FIRE PERFORMANCE OF FIBER REINFORCED POLYMER (FRP) STRENGTHENED AND THERMALLY INSULATED BRIDGE GIRDERS
(2016-12-15)Highway bridges encounter various extreme load hazards, such as earthquake, flood, blast, collision, wind and fire during their design lives. The effect of accidental, natural or man-made fire on bridges is one of the least ... -
Hydrocarbon Pool Fire Performance of Reinforced Elastomeric Bearing Pads
(2017-08-09)Bearing pads are used as support for bridge girders to transfer the reaction forces to the substructure. They are designed to accommodate high axial loads from girder, shear deformations due to lateral thermal expansion ... -

(2022-05-16)**Please note that the full text is embargoed until 5/11/2024** ABSTRACT: This thesis examines the interaction of flood flow with bridge superstructures by considering the effects of the flow parameters, bridge geometry, ... -
HYDROLOGIC & HYDRAULIC ANALYSES TO RE-ESTABLISH TRIGG BRANCH’S JURISDICTIONAL CHANNEL TO PRE-DAM CONDITION USING HEC-HMS & HEC-RAS MODELS
(2020-12-08)Birds strikes are the most prevalent cause of airplanes strikes, and retention ponds near airports are one of the most attractive spots for both immigrant and domestic wildlife USDA (2017). Since the Trigg Lake, water ... -
IDENTIFICATION OF LEGAL AND POLICY BARRIERS TO TIMELY POST-DISASTER RECONSTRUCTION AND STRATEGY DEVELOPMENT FOR EFFECTIVE RECOVERY PROCESSES IN UNITED STATES
(2019-05-02)Communities resilient to disasters have the ability to return to the normal state quickly and with the least possible delay; however, the causes of delays in the post-disaster recovery phase remain an important concern. ... -
IDENTIFICATION OF PHASE-BASED KEY PERFORMANCE FACTORS AND THEIR BEST PRACTICES IN CONSTRUCTION PROJECTS
(2018-08-09)Delay and cost overrun in construction projects are two widespread problems arousing practitioners’ and scholars’ concerns as poor time and cost performance lead construction projects to failure. It is estimated that more ... -
Identification of Resilience Dimensions and Development of a Decision-Making System to Measure the Resilience Level of Highway Networks
(2021-12-21)Local as well as national economy and safety depend on the network characteristics of the transportation infrastructures. Destruction of transportation infrastructures causes the direct cost of the reconstruction as well ... -
IDENTIFICATION OF THE MANAGEABLE CONSTRUCTION REWORK INDICATORS AND RELATED SUCCESSFUL STRATEGIES
(2019-05-08)In construction projects whether small or large scale, in the design and construction phases, contractors and owners face numerous reworks which finally leads to schedule delays and cost overruns. Although studying the ... -
Identifying Issues Impacting Productivity Of Box Jacking Projects
(Civil & Environmental Engineering, 2013-03-20)Jacking is a trenchless construction technique used for installing underground pipeline system. Jacking method is more widely used for upgrading under capacity culverts and drainage structures under roads and railroad ... -
Identifying the Optimal Combination of Critical Roadside Slope Segments Susceptible to Rainfall-induced Failures for Minimizing Vulnerability of Highway Networks
(2022-08-11)The stability of roadside slopes is vital for the smooth operation of the highway transportation system. The failure of slopes adjacent to the highway corridors adversely impacts the network users and network operators. ... -
Impact Of A Pre-combustion Retrofit Device On Vehicular Emissions: A Case Study
(Civil & Environmental Engineering, 2007-08-23)Vehicular emissions are a major cause of air pollution in the cities worldwide. Increased numbers of vehicles and the vehicle miles traveled by them every year means that the emissions are going to have a detrimental effect ... -
