2D and 3D Numerical Modelling of Exposed Steel Base Plate Connections under Cyclic Loading
(Canadian Science Publishing, 2022-04-04)The degree of fixity at the base of steel gravity columns with exposed base plate connections is often assumed in analysis and design. However, past experiments have shown these connections do provide lateral stiffness and ... -
17-Year Elevated Temperature Study of HDPE Geomembrane Longevity in Air, Water and Leachate
(ICE Publishing, 2018-10-17)A 17-year investigation of a geomembrane (GMB) aged at 55, 70 and 85°C in air, water and leachate is reported. At test termination, the mechanical properties had only reached nominal failure in leachate and water at 70 and ... -
Brittle Rupture of an Aged HPDE Geomembrane at Local Gravel Indentations under Simulated Field Conditions
(ICE Publishing, 2014-02)The susceptibility of a 1.5 mm thick high-density polyethylene geomembrane to brittle rupture from long-term stress cracking in a simulated municipal solid waste landfill liner is examined. The geomembrane was pre-aged in ... -
Impacts of Warming Winters on Recharge in a Seasonally Frozen Bedrock Aquifer
(Elsevier, 2020-07-31)Under conditions of a changing climate, winters are predicted to be warmer and wetter in the northern hemisphere. Yet, the impacts of increasing midwinter snowmelt and rain-on-snow (ROS) events on groundwater recharge are ... -
Hydrogeologic and Climate Drivers of Water Isotopes in Fractured Rock: A Word of Caution for the Use of Groundwater Isoscapes in Humid Continental Settings
(Elsevier, 2020-03-16)Time-discrete groundwater isoscapes are commonly used as a proxy for the weighted mean isotopic value of precipitation and to infer recharge processes. In fractured rock environments, however, the complete removal of ... -
Groundwater Recharge, Flow and Stable Isotope Attenuation in Sedimentary and Crystalline Fractured Rocks: Spatiotemporal Monitoring from Multi-Level Wells
(Elsevier, 2019-01-25)The complexities of fractured rock systems necessitate the use of multi-level monitoring wells for the measurement of isotopic tracers with depth. These methods, however, are rarely employed in groundwater flow studies, ... -
Computational and Empirical Water Quality Modeling in Lakes and Ponds
The water quality issues facing aquatic systems have made managers and stakeholders seek help from computational and empirical models. A 3-D hydrodynamic and biogeochemical model was applied to storm-water ponds in the ...
