a rural kansas watershed that is ungauged has an area of 475 acres and a main channel length of 6870 feet with an average slope of 100 feet per mile. what is the peak flow in ft3/s for a 15-minute unit hydrograph using the scs unit hydrograph method
Answer:
[tex]\mathbf{Q_p =682 \ \ ft^3/s}[/tex]
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 [tex]t_c = 0.0078L^{0.77} S^{-0.385}[/tex]
where;
L = 6870
S = 5/264
[tex]t_c = 0.0078(6870)^{0.77} (\dfrac{5}{264})^{-0.385}[/tex]
[tex]t_c =32.34[/tex] min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time [tex]T_l = 0.67\times t_c[/tex]
[tex]T_l = 0.67\times 32.34[/tex]
[tex]T_l = 21.6678\ min[/tex]
The time to peak i.e
[tex]T_p = \dfrac{D}{2}+ T_L \\ \\ T_p = \dfrac{15}{2}+ 21.6678 \\ \\ T_p = 29.168 \ min[/tex]
[tex]T_r = \dfrac{T_p}{5.5} \\ \\ T_r = \dfrac{29.1678}{5.5} \\ \\ T_r = 5.30 \ min[/tex]
Since D = 15 min is not equal to [tex]T_r[/tex], then we hydrograph apart from [tex]T_r[/tex] duration lag time.
Then;
[tex]T_p \ ' = T_p + \dfrac{D-t_r}{4} \\ \\ T_p \ ' = 29.168 + \dfrac{15-5.30}{4} \\ \\ T_p \ ' = 31.593[/tex]
Now, we need to determine the peak discharge [tex]Q_p[/tex] by using the formula:
[tex]Q_p = \dfrac{484 \times A}{T_p \ '}[/tex]
where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²
[tex]T_p \ ' = 31.593/60[/tex]
∴
[tex]Q_p = \dfrac{484 \times 0.7422}{\dfrac{31.593}{60}}[/tex]
[tex]\mathbf{Q_p =682 \ \ ft^3/s}[/tex]

Picture in your mind a landform that is almost all bedrock. It could be a place like Papago Park, Camelback, Zion National Park, or another landform that sticks in your mind. Why do you see the exposure of so much bedrock, as opposed to soil covering the landform
Answer:
This happens because the particles removed from the rock move very slowly, generating an accumulation of particles, because the rate of weathering is faster than the movement of particles.
Explanation:
On a rocky relief, the weathering rate is very fast. This is because this type of region is susceptible to all the factors causing weathering, which speeds up the execution of this process. As you may already know, weathering is the geological process that allows a rock to be broken down into small sediments that form the soil.
In a rocky relief, it is possible to see an accumulation of these sediments that are particles and much bedrock that cover the relief intensely. This happens because the movement of these particles is very slow, in relation to the speed of the weathering of the rock.

Explanation:
Not all mountain systems were once volcanoes. Many of them are belts of rock that crumpled when two continental plates collided, forcing one plate to slide beneath another. The _______ is an example of a mountain range that formed this way, among many, many others.
Answer: Himalayan Mountain
Explanation:
It is believed that mountains are as a result of aftermath of volcanoes but The Himalayan mountain amongst others is an example of a mountain range which is said to have been formed from the collision Eurasian plates and the Indian plate which started out from the crumpling and buckling of the Eurasian continental plates over the Indian continental plates and acted upon by compression forces which caused the entire continental crust to fold upwards forming the mountain.
Another example is the The Appalachian Mountains.
Japan, China and the US are the top 3 consumers of seafood and 1.2 billion people depend on seafood as their daily source of protein. However our fishing stocks have decreased by 90% between 1950 and 2011. In addition, certain commonly used fishing practices cause horrendous damage to the rest of ocean ecosystems. A study in 2006 estimated that, if fishing continues at the current rate, all the world's fisheries will have collapsed by the year 2048.
What might be causing greater and greater demand for seafood?Why do you think we have seen a dramatic increase over the last 50 years in how many fish we are able to catch?
Answer:
Explanation below
Explanation:
Asia and the Pacific region have continued to remain the world's largest producer of fish. Various researchers have identified certain benefits of consuming seafood, which have caused greater demand for them. Apart from being ideal source of vitamins, fish is also rich in Omega 3 fatty acids, which can help prevent high blood pressure, cancer and heart diseases. Seafood also strengthen the immune system through their antioxidants.
Rapid advances in fishing technology have led to the dramatic increase over the last 50 years in how many fish we are able to catch. Most people in the fishing business now use factory ships, in place of fishing vessels. These ships are can stay at the sea for several weeks and they have all the necessary equipment that can be used to either freeze of tin fish that they catch using their hunting ships.
The factory ships need to get full before they can return to base and this has caused over a 7% growth in catches every year.

1.) What is a brief history of the island of Jamaica. Beginning with the native Indian population and going through Spanish exploration to the introduction of Africans, to modern day.
Answer:
Explanation:
The original inhabitants of Jamaica are believed to be the Arawaks, also called Tainos. They came from South America 2,500 years ago and named the island Xaymaca, which meant ““land of wood and water”. The Arawaks were a mild and simple people by nature.
The name Jamaica is derived from Xaymaca, the Taíno-Arawak name for the island, which translates, as 'isle of springs'. Jamaica was charted by Christopher Columbus during his second voyage and the first Europeans to arrive on the island were the Spanish in 1509.
The first Africans to arrive in Jamaica came in 1513 from the Iberian Peninsula. When the British Empire captured Jamaica in 1655, many of them fought with the Spanish, who gave them their freedom, and then fled to the mountains, resisting the British for many years to maintain their freedom, becoming known as Maroons

How does urbanization (paving, etc.) affect runoff and infiltration in a small, previously forested drainage basin
Answer:
Run off increases and infiltration decreases
Explanation:
Urbanization usually involves activities such as paving, etc by people who moved into the area in order to make it more presentable and sophisticated. Urbanization affects runoff by increasing it because water can’t be absorbed into the paved structures so it ‘runs’ off to a place where absorption is high.
Infiltration which involves water being absorbed into the soil also decreases as a result of the pavings.

A stone dropped freely from 72m height of
the tower and reaches the "ground on 6 seconds
calculate acceleration due to gravity of that stone
At what condition does the acceleration due to
gravity becomes Zero
When the initial velcity is 12 m/sec in that condition the acceleration due to gravity becomes Zero.
What is acceleration?The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The height from the stone drop,h= 72 m
t is the time period=6 sec
From Newton's second equation of motion;
[tex]\rm h = ut +\frac{1}{2} gt^2\\\\[/tex]
The condition does the acceleration due to gravity becomes Zero will be;
The gravitational acceleration is zero;
[tex]\rm h = ut +\frac{1}{2} \times 0t^2\\\\h=ut \\\\ 72 =6u \\\\ u= 12 m/sec[/tex]
Hence when the initial velcity is 12 m/sec in that condition the acceleration due to gravity becomes Zero.
