Substudy 1: To evaluate the effects of converting
a hardwood stand to Norway spruce on quality, quantity, and
timing of streamflow.
Substudy 2: To determine the effect of each
cutting-practice level on water quality and quantity
Substudy 3: A) To provide biomass information
and to study plant succession and hydrologic performance under
natural revegetation of an area recovering from intensive
use of herbicides. B) To measure the effects of managing portions
of a watershed with a selective herbicide on the quality,
quantity, and timing of streamflow.
Substudy 4: A) To determine the effects
of a dense road network on stream chemistry from a 150-acre
watershed. B) To determine the effects of a dense road network
plus an intensive harvest operation on stream chemistry. C)
To determine changes in watershed hydrology including annual
water yield, peakflow rates, and stormflow volumes.
Substudy 5: To determine changes in soil
chemistry, soil leachate chemistry, and streamflow chemistry
resulting from increased application of nitrogen and sulfer.
Substudy 6: A) To determine the effects
of intensive mechanical site preparation on the quality, quantity,
and timing of streamflow. B) To evaluate the effectiveness
of mechanical site preparation on the growth and survival
of planted Japanese Larch. C) To obtain information on the
effects of mechanical site preparation in modifying acid deposition
Substudy 7: To measure the effects of fertilization
on the quantity, timing and quality of streamflow from a forest
Substudy 8: To investigate changes in selected
chemical properties of water as it passes through the land
phase of the hydrologic cycle and to determine the dynamic
changes in stream water quality during storm events.
Substudy 9: A) To evaluate the effects of
applying agriculture ground limestone to the riparian zone
of a forested watershed on streamwater and soil chemistry.
B) To obtain invertebrate populations data to evaluate biological
change that may occur as a result of the liming treatment.
Substudy 10: To determine the effect of
forest fertilization on the water quality and the hydrologic
balance of a forested basin.
Substudy 11: To determine what influences
non-research timber harvesting methods (particularly clearcutting)
have on water quality and to compare these influences to experimental
results from the Fernow Experimental Forest and elsewhere.
Substudy 12: To provide quantitative information
on natural water quality characteristics from an undisturbed
forested watershed in order to provide benchmark data against
which water quality data from treated areas can be compared.
