Objective(s): To examine the movement of water within the valley snow- packs and the factors which influence its behaviour; to examine the ways in which the snowdrifts blocking the stream channels are breached; to obtain information on the thermal and mechanical processes responsible for downcutting and enlarging the stream channel formed through the snow drifts.

Project Description: As part of an ongoing study in which field work was conducted in 1989 and 1990, this year's work will involve a study of the effects that snowdrifts can have on blocking the movement of meltwater in the McMaster River during the spring. Snowdrifts located at several sites along the river will be monitored to determine how they can alter the river's course, how these drifts are eventually broken down, and how these drifts affect spring flooding downstream.
