DESCRIPTION:
Although the
geology of McGregor Model Forest appears "fixed" relative to ecological processes
at work, in fact a variety of glacial and post-glacial processes have wrought
significant landscape changes since the Quaternary. More recently,
within the past 10,000 years, hydrological processes involving the McGregor
River and other watercourses have contributed to the dynamics of the McGregor
landscape.
Knowledge about these processes provides an important background for interpreting ecological patterns and processes on the landscape, as well as a context for addressing the potential effects of land management activities.
One component
of this project aimed at the depositional and erosional processes that account
for the existing geomorphological character of the McGregor landscape.
The approach consisted of a literature review of surficial sediment deposition
and erosion models having probable application to the McGregor situation;
interpretation of small scale landform events responsible for the area's surficial
deposits; and preliminary mapping (1:250,000) of surficial deposits based
on airphoto interpretation and field work. The second component characterized
the current and historical flood and sediment discharges of major McGregor
streams, including an evaluation of their sensitivity to change. The
approach was to analyze old fluvial deposits and channel wandering through
sequential airphotos and field interpretation.
