The terms often used to describe the United States' position or rank in the international system is hegemon, hegemony, or super power. All of these words signify the idea that the U.S. following the fall of the Soviet Union became the most powerful state in the international system thus signifying its rise to hegemony or super power status in that no other state could match its military and economic strength.
At low latitudes, the thermocline is a zone of rapid temperature
over a relatively short depth. it is associated with a similar depth zone marked by a change in density called the pycnocline.
Answer:
Explanation:
Given that:
Area = 475 acres
The length of the channel (L) = 6870 feet
The average water shield slope (S) = 100 feet/mile
Since; 1 mile = 5280 feet
Burst duration D = 15 min
∴
100 feet/mile = 100/5280
The average water shield slope (S) = 5/264
Using hydrograph method:
The time of concentration
where;
L = 6870
S = 5/264
min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time
The time to peak i.e
Since D = 15 min is not equal to , then we hydrograph apart from duration lag time.
Then;
Now, we need to determine the peak discharge by using the formula:
where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²
