Specialties
The Rational Method
Open Channel Flow
Soils
Concrete
100
This subspecialty is most likely to classify soil types and perform a cone penetration test to determine soil bearing capacity.
Geotechnical
100
What are the units of the variable "A" in Q=ciA?
Acres
100
Which is a type of open channel flow: a forced water main, sprinkler system piping, a driveway culvert
driveway culvert
100
This type of soil has the smallest particle size
clay
100
This ancient civilization invented concrete, but their formulation was lost in medieval times.
Romans
200
This specialty deals primarily with designing the framing and foundations of buildings, bridges, etc.
Structural
200
Which of the following is likeliest to have the smallest rainwater runoff coefficient: roof, forest, lawn?
Forest
200
The length of the channel boundary in contact with the flowing fluid
wetted perimeter
200
Classify this soil: 20% clay, 40% sand, 40% silt.
loam
200
This component of concrete acts as the structural backbone.
aggregate
300
This specialty designs stormwater systems, dams, and water treatment plants.
Hydrology or Water Resources
300
The rational method can only be used for areas less than...
1 square mile (640 Ac)
300
The greater this variable is, the smaller the flowrate.
roughness coefficient
300
In this soil field classification test, one tries to roll a moist soil sample into a ball.
putty test
300
The purpose of this component is to increase the tensile strength of concrete.
rebar, or steel reinforcement
400
This specialty designs and optimizes interstates, airports, roads, etc.
Transportation
400
This can be obtained from tabular data compiled by NOAA, the National Oceanic & Atmospheric Administration.
rainfall intensity
400
A higher value for this variable, the ratio of the area to the wetted perimeter, indicates a more efficient channel.
Hydraulic radius
400
This type of soil is most likely to fall apart in the putty field test.
sand
400
This is a critical consideration of reinforced concrete design because it can account for 40-60% of the cost.
formwork
500
What’s the difference between a doctor and a Civil engineer?
A bad doctor only kills people one at a time.
500
Which would have the lower rainfall intensity: a 100-yr storm event or a 5-yr storm event?
5-yr event
500
Which of these would likely have the lowest roughness coefficient: concrete trench, swamp, plastic pipe
plastic pipe
500
Which of the following is likely to have the smallest load bearing capacity: granite, clay, or sand
clay
500
This is most likely the cause of a footing failure by punching shear.
inadequate footing thickness
