Answer 3

continuity

Question 4

Meetings are least important in the culvert design process.

Question 5

When designing an inlet apron lining, cross-sectional area is computed by using the ____________________ depth together with barrel dimensions.

Question 6

A site visit must be conducted during culvert design to verify the topography and note any features that are not clearly depicted on the maps.

Question 7

When computing the cross-sectional area of a culvert and the face of the culvert is skewed, use the dimensions ____ to the long axis of the barrel.

A)parallel
C)not associated with
B)perpendicular
D)skew

Question 8

An important environmental consideration when designing a culvert is the potential for ___________________ downstream from the culvert.

Question 9

Generally, the culvert should follow the streambed only in horizontal alignment.

Question 10

What is an advantage of designing a new culvert over replacing an old culvert?

A)fewer existing streams
C)only outlet control
B)fewer existing constraints
D)previously existing utilities

Question 11

____ is a key design parameter and constitutes the maximum height of headwater that will be allowed for the design storm.

A)Allowable headwater elevation
C)Design outcome
B)Embankment
D)Backwater

Question 12

The engineer's job in designing a culvert ____________________ often is made difficult by the physical constraints within which the design must be accomplished.

Question 13

An important environmental consideration to culvert design is ____.

A)type of soil
C)existing culverts
B)fish habitat
D)apron lining

Question 14

A typical constraint when replacing a culvert is the presence of established improvements and utilities adjacent to the existing culvert and stream.

Question 15

In many culvert replacements, the existing culvert is ____________________ inadequate because of various factors.
