of British Columbia and the B.C. Ministry of Forests, with an objective of increasing our understanding of hydrological processes by focusing on subsurface flow, spatial variation of climate data and snow accumulation and ablation dynamics. This process based experimental setup will provide data to justify future physically based modeling of the hydrological response and the subsequent effects on stream flow at different scales, ranging from the hillslope to watershed. The project consists of the three major parts subsurface/preferential flow, spatial variation of climate data and snow dynamics. The spatial variation and dynamics sub-projects have been started in mid 2005. In order to achieve the set objectives the year 2005 and the first part of 2006 have been used for climate station and instrumentation design and set-up as well as for testing the instruments. This report consists of 3 parts. The first part is describing the spatial variability analysis of climate data in the watershed. Parts 2a and 2b investigate two aspects of subsurface/preferential flow. Part 3 is dedicated to ongoing project on snow accumulation and ablation dynamics in rain-on-snow dominated watersheds. 2
