Forest Management Practices: Relationships with Stream Water

# 72 Long -Term Monitoring of Stream Discharge
  • Objective:
    • Substudy 1: To evaluate the effects of converting a hardwood stand to Norway spruce on quality, quantity, and timing of streamflow.
    • Substudy 2: A) To provide basic 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 3: 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 effects. Substudy 4: To measure the effects of fertilization on the quantity, timing and quality of streamflow from a forest watershed.
    • Substudy 5: To evaluate if there is a difference in soil moisture content of north- and south-facing basins.
    • Substudy 6: To harvest the present timber stand by practical, even-age methods and to observe the effects of this harvest on quantity, timing, and quality of streamflow.
    • Substudy 7: A) To predict the dependable yield, both annual and seasonal, of the Princeton watershed. B) To improve the basic understanding, methods, and procedures for problems of this kind. C) To estimate the effect of different forest practices on the water yield of the Princeton watershed.
    • Substudy 8: To determine the effects of clearcutting and silviciding watersheds 6 and 7 upon water quality, including turbidity, water temperature, pH, methyl orange alkalinity, specific conductance, and taste and odor (silvicides).
    • Substudy 9: A) To determine the effect of complete vegetation removal upon the quantity of streamflow annually, by seasons, during high and low flows of two forested watersheds. B) To determine for the two watersheds the effect of vegetation removal on the upper slope as compared to the lower slope. C) To obtain as full an understanding as possible of the hydrology of the two watersheds.
    • Substudy 10: To measure effects of careful road building and of diameter-limit cutting on quantity and quality of forest streamflow.
  • Objective:
    • 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 effects.
    • Substudy 7: To measure the effects of fertilization on the quantity, timing and quality of streamflow from a forest watershed.
    • 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.
  • Objective:
    To determine the effects of forest management practices on water quality and quantity.
  • Objective:
    1) To evaluate the cost to a municipality of reduced water yield from reforesting abandoned land.
    2) To quantify the hydrologic impacts of forest management techniques applied during the development of planted stands.

  • Objective:
    To continually monitor forest hydrology parameters at the Hubbard Brook Experimental Forest.
  • Objective:
    To monitor rainfall, streamflow and chemical composition of water from several sites in Kentucky.
