The chemistry, mineralogy, and rates of transport of sediments in the ...

ottom near the site of addition .- It was observed that small rivers and
streams were not immediately able-to carry increased sediment supply derived
from natural and technological disturbances in their watersheds . We feel
that careful technological activities in this region will not greatly affect
sediment transport regimes of larger rivers .
We strongly propose . that small experimental research watersheds be
established in representative areas within, and outside of proposed development
routes in the Mackenzie Valley and Northern Yukon . These experimental
research watershed's should be carefully maintained to measure the effects of
technological activities on :important components -of the watershed ecosystem,
to experimentally test many hypotheses concerning the interaction of controlled
terrain disturbance and watershed- response, and to provide undisturbed control
for future reference purposes . We recommend that the present network of
discharge, suspended ., sediment, and meteorological stations be expanded,' especially
to - inc lude more small watersheds in a variety of regions within the Mackenzie
Valley and . northern Yukon .,-
