Abstract
Forest disturbances significantly affect snowmelt dominated watersheds.
Given that snowmelt from mountain regions provides up to 80% of the
annual stream
ow in the North American west, disturbances in these watersheds
will impact water availability for downstream users. This study
used eld data from stand-scale studies to represent forest disturbances in
a hydrological model in order to quantify the potential snow hydrology response
to varying spatial extent of disturbance. The sensitivity of snow accumulation
and ablation response increased with disturbance severity and
extent of disturbance. Results may provide water resource management
with a greater understanding of the potential impact on post-disturbance
snowmelt runo ff.
