Overview

Dennis Parkinson was affiliated with the University of Calgary in Canada. Their research primarily focused on the field of Engineering, with specific involvement in Civil and Structural Engineering as well as Safety, Risk, Reliability and Quality.

The main topics covered in their work included:

  • Dam Engineering and Safety
  • Soil and Unsaturated Flow
  • Geotechnical Engineering and Analysis

Parkinson contributed to academic literature with a number of publications, including a recent paper titled Recollections and reflections on the construction of Scammonden dam (1966-1970), published in 2023 in the journal Dams and Reservoirs. This paper has been cited twice.

Their frequent coauthor was J. A. Charles, with whom they collaborated on at least one publication. Parkinson's work appeared primarily in the journal Dams and Reservoirs.

Throughout their career, Parkinson concentrated on engineering themes that involved complex structural and geotechnical challenges relating to dam construction and safety. Their expertise extended to understanding soil behavior and flow in unsaturated conditions, which are critical components in civil infrastructure projects involving earthworks and water retention.
