Description :
A field study was conducted to analyze root throw and associated sediment transport in Haw Creek Watershed, Canadian Rockies. A large crown fire in 2003 allowed the opportunity to study pre-fire and post-fire root throw. A tree population dynamics model is integrated with a root throw transport model calibrated for the Canadian Rockies to examine the temporal dynamics of sediment transport. Fire is incorporated as a disturbance that initiates development of a new forest, with the model cycling through generations of forest. Using this integrated model, the AA. strive for improved understanding of how tree population dynamics driven by wildfire disturbance influences the temporal dynamics of sediment transport due to root throw in the Canadian Rockies.
