1. Which river 'load' is responsible for transporting the majority of sediment downstream?
bedload
suspended load
dissolved load
2. What type of bed material would be most likely for a river located high in a watershed?
boulders
sand
clay
3. Which particle size (listed below) would be the last to settle out of a river that slows down as it flows into a lake?
sand
silt
clay
4. What would be the discharge for a river that has a depth of 3 m, a width of 4 m, and a velocity of 1 m/s?
12 m3/s
7 m3/s
12 cfs
7 cfs
5. Which of the following is NOT a factor that determines the carrying capacity of a river?
discharge
channel shape
gradient/slope
none of the items listed are a factor
all of the items listed are factors
6. Which letter on the hydrograph would best represent flooding in an urban development: with a large percentage of impermeable surfaces?
A
B
C
7. Which letter on the hydrograph would best represent flooding in rural land: with natural channels?
A
B
C
8. Which of the following correctly summarizes the main changes in a river as it flows downstream?
The slope/gradient becomes more gentle; the channel becomes wider & deeper; discharge increases & more sediment is carried.
The channel becomes wider & deeper; less sediment can be carried; the discharge is lower.
The discharge increase; the channel becomes narrower.
The slope/gradient becomes steeper; discharge increases; the channel becomes wider & deeper
9. Which of the following options would be a reasonable landform feature found on the upper section of a river (high in the watershed)?
ox-bow lake
floodplain
waterfall
meander
10. Study the water cycle diagram… What is the name of the movement of water identified as #6 on the diagram?
infiltration
precipitation
throughflow
11. Not that you would be silly enough to build a home on a floodplain… Let’s, for argument’s sake say you are in fact THAT silly. Which location, in the diagram below, would be the WORST place to build & why?
Location A: because the current slows down on the inside of the river bend, causing sediment to be deposited
Location B: because the strongest current is directed at the outside of the river bend, causing erosion of the outer bank
12. Along which section of a river is regional flooding most likely?
the upper section near the headwaters
the middle section
the lower section near the mouth
