Question 1

What is 'interception' in forest hydrology?

Accepted Answer

Precipitation captured by the forest canopy before reaching the ground

Answer

Canopy interception is the portion of precipitation retained on leaves and branches that evaporates back to the atmosphere without reaching the forest floor.

Question 2

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

Accepted Answer

Lateral flow (throughflow)

Answer

Lateral flow (throughflow) occurs when water moves horizontally through the soil profile, often above a confining layer, and can contribute to streamflow.

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

Paired watershed studies calibrate two hydrologically similar catchments, treat one, and attribute streamflow differences to the treatment.

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

Riparian buffers intercept sediment, nutrients, and pollutants before they enter streams, while also providing shade and bank stability.

Question 5

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

Accepted Answer

Infiltration capacity

Answer

Infiltration capacity is the maximum rate at which a soil can absorb incoming water; when rainfall exceeds this rate, Hortonian overland flow occurs.
