Reliability Assessment of Concrete-Filled RHS Beam-Column Design Provisions (Preprint)
(Springer, 2023-08-01)Revisions were recently proposed to the way in which concrete-filled hollow structural section members are handled in CSA S16. These revisions were based on previous research, comparisons to experiments, and an approximate ... -
Design of Single-Sided Fillet Welds under Transverse Load (Postprint)
(American Society of Civil Engineers, 2022-09-01)In North American steel design specifications, a directional strength-enhancement factor is used to increase the predicted strength of fillet welds subjected to transverse loading (i.e., loading at 90° to the weld axis). ... -
Experimental tests on fillet and PJP welds in CHS moment T-connections (Postprint)
(Elsevier, 2022-09-01)An experimental program was developed at Dalhousie University to test various unreinforced circular hollow section (CHS)-to-CHS 90° T-connections subjected to branch in-plane bending moment with the objective of determining ... -
Chord-end RHS-to-RHS and CHS-to-CHS X-connections with rigid cap plates: Stress concentration factors (Postprint)
(Elsevier, 2021-04-01)For rectangular hollow section (RHS)-to-RHS and circular hollow section (CHS)-to-CHS connections situated near a truss/girder end, reinforcement using a chord-end cap plate is common; however, for fatigue design, formulae ... -
Circular hollow section X-connections near an open chord end: stress concentration factors (Postprint)
(Elsevier, 2021-02-01)This paper presents a numerical finite element (FE) investigation to determine stress concentration factors (SCFs) for circular hollow section (CHS)-to-CHS X-connections near an open chord end. Previous large-scale experiments ... -
Coastal groundwater model calibration using filtered and amplified hydraulic information retained in the freshwater–saltwater interface Postprint
(Springer, 2022-07-22)Coastal groundwater flow is driven by an interplay between terrestrial and marine forcings. One of the distinguishing features in these settings is the formation of a freshwater lens due to the density difference between ... -
Drone-based characterization of intertidal spring cold-water plume dynamics Postprint

Blue-Green and Benthic: A Workshop on Monitoring, Mitigation and Management of Cyanobacteria in Atlantic Canada. Final Report.
(2023-01-12)WORKSHOP SUMMARY Since the 2018 Atlantic Canadian Cyanobacteria Workshop, we have seen a rapid increase in the number of waterbodies (recreational and drinking water supplies) under public advisories, exposing gaps in ... -
Biodegradation kinetics of individual and mixture non-steroidal anti-inflammatory drugs in an agricultural soil receiving alkaline treated biosolids
(Elsevier, 2021)Land application of biosolids is one potential source of pharmaceuticals and personal care products (PPCPs) into agricultural soils. Degradation is an important natural attenuation pathway that affects the fate and transport ... -
Characterizaing sediment physical property variability for bench scale dewatering purposes
(Thomas Telford Ltd, 2020)A field sampling program was undertaken to assess the variability of physical characteristics of contaminated sediments in a large (160 ha) effluent stabilization lagoon. The objective of this paper is to use this “field ... -
Particle Size Effects on Breakage of ACT Aggregates Under Physical and Environmental Loadings
(American Society of Civil Engineers, 2020)Aggregates manufactured from fine-grained thermal waste residues using accelerated carbonation technology (ACT) represent a potential sustainable alternative to natural aggregates. However, for these manufactured products ... -
Development of a leaching procedure to asses the risk of uranium leaching due to construction and demolition waste
(Elsevier, 2018)Naturally-occurring uranium can be found at elevated concentrations in groundwater throughout the world, with the potential to cause kidney damage in chronically exposed individuals. Empirical evidence shows that uranium ... -
Using a geotextile with flocculated filter backwash water and its impact on aluminium concentrations
(Elsevier, 2018)The use of geotextiles (i.e. geotextile tubes) in wastewater treatment applications is ever increasing. This paper examines the potential of using a geotextile to improve upon the treatment of aluminium present in a filter ... -
The effect of different dewatering techniques on resulting effluent particle size.
(Canadian Science Publishing, 2020)A paucity of literature has compared geotextile dewatering methods to more conventional dewatering methods (i.e. centrifuge, sedimentation) in the context of how geotextile dewatering performs at reducing particulate matter ... -
Quantifying hydraulic conductivity spatial variability for a cement-based solidification/stabilization (S/S) remediation project: a case study.
(Canadian Science Publishing, 2021)This paper presents statistical analyses of hydraulic conductivity data collected from an existing cement-based solidification/stabilization (S/S) system. The goal is to characterize the spatial variability of hydraulic ... -
Examining the Ultraviolet Optical Screening Tool as a Viable Means for Delineating a Contaminated Organic Sediment
(Elsevier, 2021)Rapid and accurate delineation of contaminated sediments in marine environments is critical for the effective assessment of site risks and the development of appropriate remedial action plans. In this study, a new application ... -
Fate and transport of particle matter during geotube dewatering of a dioxin and furan (PCDD/F) contaminated sediment.
(Elsevier, 2022)Geotextile tube dewatering is a pre-treatment method utilized in the remediation of high-water content materials (i.e. sediments and slurries). However, given the association some contaminants (e.g. dioxins and furans, ... -
Evaluating the movement of dissolved porewater species through a marine sediment 51 years after establishment of a pulp and paper effluent stabilization basin
(Canadian Science Publishing, 2022)Over 50 years ago, a marine estuary was converted to a wastewater stabilization basin for treatment of primarily pulp and paper effluent. As a result, the basin was immediately converted to a “freshwater” environment and ... -
Low impact development effects on aquifer recharge using coupled surface and groundwater models
(ASCE, 2018)Low impact development (LID) is promoted as a sustainable management practice for stormwater in urbanized catchments. While the positive effects of LID features on surface water hydrology and water quality have been ... -
Spatiotemporal assessment (quarter century) of pulp mill metal(loid) contaminated sediment to inform remediation decisions
(Springer, 2017)A bleached kraft pulp mill in Nova Scotia has discharged effluent wastewater into Boat Harbour, a former tidal estuary within Pictou Landing First Nation since 1967. Fifty years of effluent discharge into Boat Harbour has ...
