GEOMORPHOLOGY IN HAIDA GWAII

Geomorphology is a unique field of earth sciences, involving the study of physical processes on the earth’s surface and its changing landscape. Here in the Pacific Northwest, the combination of mountainous terrain and historical glaciation result in highly variable earth-processes; prime territory for glacial and fluvial geomorphologists.
 

While taking the course GEOB 405: Fluvial Geomorphology, taught by Geography Department Head Marwan Hassan, I came across two compelling journal publications discussing an observed coupling relationship between hillslope and channel drainage area. In Montgomery & Foufoula-Georgiou (1993), a GIS-based analysis of DEMs for river networks in California, New York, Oregon, and Tennessee indicate that the extent of debris-flow domination in a channel can be determined from an inflection of the slope-drainage area relation. In the more recent study by Hassan, et al (2018, October), this hillslope-channel coupling is further examined while looking at two previously glaciated basins in Haida Gwaii, BC. Curious to learn more about this relationship and keen to better develop my skills in hydrological modeling, I choose to delve into this topic in greater detail.
