The flood of the century: the beginning

Listed below are several statements.  If the statement is a reason that the Red River of the North's flooding can be serious, circle "True"; if it is not a reason that the Red River of the North's flooding can be serious, circle "False".

True   False   1) The Red River of the North flows north.

True   False   2) The months with the most precipitation are April and May, which is when the flooding occurs.

True   False   3) Snow melting off of nearby mountains flows into the Red River and several of its tributaries.

True   False   4) Ice jams tend to form on the river in the north, thus blocking the already melted snow in the south.

True   False   5) The Missouri River flows into the Red River, thus adding a tremendous amount of water.

True   False   6) The Red River Valley is very flat; so when the river floods, the water covers a large area..

True   False   7) The Red River is a young (< 10,000 years old) river; thus it has yet to carve a significant valley-floodplain.

True   False   8) The slope of the Red River is very steep; thus the water moves very rapidly.

True   False   9) The slope of the Red River is very shallow; thus the water has a tendency to pool.

True   False   10) Too many people live in the Red River Valley, which has led to massive erosion problems.

Andy Nov. 16-17 12 inches 13.6 inches
Betty Dec. 16-18 8.7 inches 38.2 inches
Christopher Dec. 20 4.2 inches 42.4 inches
Doris Jan. 9-11 8.8 inches 56.5 inches
Elmo Jan. 14-16 0.4 inches 57.1 inches
Franzi Jan. 22-23 8.6 inches 67.4 inches
Gust March 4 0.2 inches 83.3 inches
Hannah April 4-6 6.3 inches 97.4 inches

16) The normal snowfall for Grand Forks is 41 inches.  How many more inches of snow did it receive during the 1996-97 winter?

57.6 inches

17) What percentage of the normal snowfall was the snowfall during the 1996-97 winter?

98.6 / 41 = 2.404; 240% of normal
 

18) The city of Fargo received even more snow - 117 inches of snow!  Convert both 98.6 inches and 117 inches to feet and inches.

Grand Forks: 8.216... feet which (about) is 8 feet 3 inches (8 feet 2 inches is also OK)

Fargo: 9.75 feet which is 9 feet 9 inches

19) How much taller (or shorter) is the amount of snow when compared to the ceiling in your classroom?

Grand Forks:  These answers will depend upon the height of your ceiling

Fargo:
 

20) How much snow did the eight blizzards alone contribute to the total accumulated snow in Grand Forks?  What percentage of the total accumulated snow in Grand Forks was a result of the eight blizzards?

49.2 inches, or 4 feet 1.2 inches;  49.2/98.6 = .4989, or roughly 50%
