IntroductionWho am I?

• Physical Geography and Geology: SFU, Calgary, McMaster, UBC

• Professor at Guelph in Physical Geography and Earth Surface Science for 25 years

• ‘pseudo-retired’ Adjunct Professor in River Dynamics Research Group, SFU

IntroductionWhat is my research program?

• interdisciplinary studies of sedimentary processes in rivers and lakes, including:

- dunes on river beds

- continuous turbidity currents

- underwater debris flows

What is a river?

• a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river (https://en.wikipedia.org/wiki/River)

• synonyms: watercourse, waterway, tributary, stream, rivulet, brook, inlet, rill, runnel, freshet, bourn, creek

Why are rivers important?

• main conduits for the transfer of water, sediment and nutrients to lakes and oceans

• water supply, health and sanitation, agriculture, navigation, hydroelectric power, industry, aquatic habitat, recreation, aesthetics, culture, spirituality

Who studies rivers?

• ecologists, engineers, sedimentologists, geomorphologists

• fluvial (river) geomorphology (surface of earth): the study of processes and landforms associated with rivers

three zones based of the dominant sedimentary processes operating within each zone:

• Zone 1: sediment production

• Zone 2: sediment transfer

• Zone 3: sediment deposition
