Answer 2

Are designed to quickly drain road surfaces from the center of the road to the side ditches.

Question 3

What is a disadvanged of insloped roads?
Water is draining to the uphill side and needs to be drained under the road through culverts.
They require a permit from the Army Corps of Engineers.
They are hard to traffick because of the uphill pitch.
Water is draining to the downhill side and might cause erosion.

Answer 3

Water is draining to the uphill side and needs to be drained under the road through culverts.

Question 4

Turnout ditches …
Are sections in a forest road that allow vehicle traffic to pass loggin machinery.
Are only used in mountainous terrain.
Are the main cause of erosion in a forest.
Should be installed at appropriate intervals to disperse water collected in the road side ditches.

Should be installed at appropriate intervals to disperse water collected in the road side ditches.

Answer 14

The region and the drainage area.

Question 15

When can a perennial or intermittent stream be crossed without providing a normal passage for water or aquatic animals within the channel?
Only during droughts.
Only during the winter.

Always.

Answer 15

At no time.

Question 16

Stream crossings according to the Alabama’s Best Management Practices for Forestry include:

Fords and log crossings.
Fords and culverts.
Culverts.

Answer 16

Log crossings, fords, and culverts.

Question 17

When the logging operation is complete …
Log crossings can remain in place becasue they degrade over time.
all log crossings must be removed.
Log crossings have to be converted to permanent fords.
Log crossings can remain in place for later logging use.

Answer 17

all log crossings must be removed.

Question 18

Culverts should extent at least …
One foot beyond the fill on either end.
One foot beyond the fill upstream.
One foot beyond the fill upstream and two feet beyond the fill downstream.
One foot beyond the fill downstream.

Answer 18

One foot beyond the fill on either end.

Question 19

Culverts should be installed …
Leveled.
With a 2-3% pitch downstream for self-cleaning.
In an upright position to maximize drainage.
With a pitch upstream to create a pool and additional habitat.

Answer 19

With a 2-3% pitch downstream for self-cleaning.
