B.S.F. or B.Sc.F. Bachelor of Science in Forestry Forest Hydrology and Watershed Management

Question 1

What is 'interception' in forest hydrology?

Accepted Answer

Precipitation captured by the forest canopy before reaching the ground

Answer

Water that moves laterally through the soil

Answer

Groundwater recharge from snowmelt

Answer

Evaporation from streams

Question 2

Which process describes water moving downslope through the soil above an impermeable layer?

Accepted Answer

Lateral flow (throughflow)

Answer

Infiltration

Answer

Overland flow

Answer

Percolation

Question 3

The 'paired watershed' experimental design in forest hydrology is used to:

Accepted Answer

Isolate the effect of forest treatments on streamflow by calibrating two similar watersheds

Answer

Compare two different tree species yields

Answer

Measure precipitation across two elevation zones

Answer

Compare soil carbon in two forest types

Question 4

Riparian buffer zones along streams are maintained primarily to:

Accepted Answer

Protect water quality and aquatic habitat by filtering runoff and stabilizing banks

Answer

Increase timber yield near water

Answer

Reduce wildfire risk along waterways

Answer

Provide recreational access corridors

Question 5

Which hydrologic term describes the maximum rate at which soil can absorb water?

Accepted Answer

Infiltration capacity

Answer

Evapotranspiration

Answer

Field capacity

Answer

Wilting point

Question 6

In the context of US forest policy, the Clean Water Act (1972) is relevant to forestry because it:

Accepted Answer

Regulates discharge of pollutants and requires states to manage nonpoint source pollution including forestry runoff

Answer

Banned all timber harvesting within 500 feet of streams

Answer

Mandates riparian buffer widths of at least 100 feet

Answer

Established the National Forest system
