Climate Change And Hydrological Risks Related To Railway Infrastructure In Northern Regions, Barry A. Palynchuk Phd
Climate Change And Hydrological Risks Related To Railway Infrastructure In Northern Regions, Barry A. Palynchuk Phd
Barry A. Palynchuk PhD
In this paper, the authors discuss the possible consequences of global warming on northern hydrology and their impacts on railway drainage infrastructure. How can we change actual design approaches, methods and standards to adapt, to reduce vulnerability and to improve resilience to climate change? Under current climate conditions, snow, ice and permafrost play a dominant role in the water balance in cold regions. Three areas can be distinguished: regions of continuous permafrost, regions of discontinuous permafrost and permafrost-free regions. To predict the potential climate change impacts on each region, the spatial analog and the climate variability analog approaches can be …

A combined rail system and port facility development was investigated in West Africa. The principal components are 700 km of single track heavy-haul railway and a new deepwater port near the Atlantic Ocean. A significant challenge for the project is the assessment of the tidal effects for structures located on coastal rivers whose delta is influenced by the Atlantic tides. The flow in Delta is multidimensional and assessment of hydrodynamics in this context requires physical modeling or numerical modeling. Such modeling requires more reliable data on topography, bathymetry and boundary conditions. A simplified hydrodynamic model was used for the estimation …

Approaches To Mitigating Decayed Buried Timber Within Railway Embankments, Barry A. Palynchuk Phd

During the last three years, several sinkholes have been observed along CPR railway lines in Southern Ontario. The sinkholes have formed as a result of the decay of buried timber trestles in railway embankments. Although it has not occurred the sinkholes could result in hazardous changes in track geometry under load. This study summarizes the site investigation results and remedial methods implemented at five sites in southern Ontario. Remedial methods include placement geosynthetic reinforcement, soil-cement column reinforcement and grouting of voids at the trestle bents. The design, installation methods and construction constraints for the remedial options are described in this …
Comparison Between Analytical Probabilistic And Computer Simulation Models, Using Current Design Examples, Barry A. Palynchuk Phd
Comparison Between Analytical Probabilistic And Computer Simulation Models, Using Current Design Examples, Barry A. Palynchuk Phd
Barry A. Palynchuk PhD
Closed form analytical expressions have been developed to solve several basic problems related to the hydrologic design of storm water management facilities. The collection of these analytical expressions is referred to as the Analytical Probabilistic Storm Water Models (APSWM). APSWM can be used as an alternative to the design storm simulation models in the design and analysis of storm water management facilities. In this paper, a comparison is made between APSWM and design storm simulation models as applied to an actual design case. Conventional outputs such as runoff volume, peak discharge, and peak discharge from detention ponds are reviewed and …

In late June 1998, a major storm event occurred in the Adirondack Mountains in the vicinity of Keeseville, New York about 150 miles north of Albany. This storm resulted in unprecedented damage to the Canadian Pacific Railway (CPR) Canadian Mainline along the shores of Lake Champlain. The storm caused 14 major embankment failures and washouts, numerous minor failures, severe bridge foundation scour and a major mainline derailment.
