Abstract
Glaciated headwater systems are presently poorly understood. This study aims to partially fill such research gap by characterising active geomorphic process domains in selected basins of coastal British Columbia. The framework adopted integrates static, process and process-response landscape zonations in a sediment budget approach. Accordingly, three interdependent geomorphic aspects are considered. These are (i) the spatial distribution of dominant sediment sources (shallow rapid failures), (ii) the definition and delineation of geomorphologic process domains (i.e. hillslope and fluvial) and relative transition zone, and (iii) the identification of potential linkages between area-slope plots (process domains) and landslide magnitude-frequency relations. It is anticipated that addressing the first and second research components will form a basis for the morphometric characterisation of the glaciated montane landscape of coastal British Columbia. This is an additional research goal that will be pursued and should allow explaining regional and sub-regional controls on the spatial distribution of sediment sources, the extension of process domains, and the shapes of landslide magnitude-frequency relations. Results are expected to improve our understanding of glaciated headwater systems, so that (i) a conceptual model for their functioning can be proposed, and (ii) sediment budgets for these portions of the landscape can be evaluated at different scales.
