David’s previous experience as a chef ignited a passion for cooking, making him a great person to have in a field camp. He also enjoys woodworking, mechanics and spending time outdoors with his girlfriend and Honey, the dog.
Dan McParland M.Sc., P.Geo.
Natural Channel Design
Meander Belt Assessments
Dan is a fluvial geomorphologist with environmental consulting experience in geomorphological assessment, natural channel design, storm water management, and aquatic habitat enhancement. He has completed analyses at a range of spatial scales from watershed to reach level and is skilled in both fieldwork and desktop analyses. Dan has applied his technical knowledge in watersheds throughout Canada and has experience with many different river types.
Dan completed his undergraduate studies at Queen’s University and his graduate studies at the University of British Columbia. His masters’ research examined the linkages between the physical sciences (hydrology and geomorphology) and aquatic ecology through the use of River2D and numerical models.
Since completing his M.Sc., Dan has successfully delivered numerous natural channel designs, meander belt width assessments, fish passage evaluations, and scour assessments. He is proficient with River2D and has used the software to quantify aquatic habitat, assess the effectiveness of channel designs, and determine sediment transport potential.
During his free time, Dan enjoys spending time with family and friends, golfing, skiing, and playing hockey.
Samantha Feist M.Sc.
Environmental Scientist (Geomorphology)
Samantha has a strong background in geomorphology, karst geology, and sedimentology. She completed her undergraduate studies at the University of Guelph, with an honours BSc thesis examining sediment mobilization processes using short sediment cores in Williston Lake, a large man-made reservoir in Northern British Columbia. She completed her M.Sc. in Earth and Environmental Science from McMaster University. Her M.Sc. research focussed on sedimentology in a previously contaminated cave system by examining the connections between the surface and subsurface environments. Samantha is skilled in both field based data collection and desktop analyses.
In her free time, Samantha enjoys hiking, travel, spending time with family and friends, and a hot cup of tea with the kind of book that draws you in until it’s done.
