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 ... -
HYDRODYNAMIC FORCES ON STREAM-CROSSING BRIDGES – CONSIDERATION OF FLOW PARAMETERS, BRIDGE GEOMETRY, AND DEBRIS
(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, ... -
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 ... -
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 Transit-oriented Infrastructure Investments on Property Valuations
(Civil & Environmental Engineering, 2012-04-11)The population explosion of the second half of the last century brought about increased human activity. Much of the attendant increased access to activities has been facilitated by the incredible technological advances in ... -
An Improved Model For Predicting Methane Emissions From Landfills Based On Rainfall, Ambient Temperature And Waste Composition
(Civil & Environmental Engineering, 2013-03-20)Accurately estimating the emissions of methane (CH4) and carbon dioxide (CO2) in a landfill is important for quantifying its greenhouse gas (GHG) emissions and power generation potential. Previous studies have shown that ... -
IMPROVING FLOOD FORECASTING USING CONDITIONAL BIAS-AWARE ASSIMILATION OF STREAMFLOW OBSERVATIONS AND DYNAMIC ASSESSMENT OF FLOW-DEPENDENT INFORMATION CONTENT
(2020-12-22)Accurate forecasting of floods is a long-standing challenge in hydrology and water management. Data assimilation (DA) is a popular technique used to improve forecast accuracy by updating the model states in real time using ... -
IMPROVING HYDROLOGIC PREDICTION FOR LARGE URBAN AREAS THROUGH STOCHASTIC ANALYSIS OF SCALE-DEPENDENT RUNOFF RESPONSE, ADVANCED SENSING AND HIGH-RESOLUTION MODELING
(2016-05-18)Due to urbanization and climate change, large urban areas such as the DallasFort Worth Metroplex (DFW) area is vulnerable not only to river flooding but also flash flooding. Due to the nonstationarities involved, projecting ... -
