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

Answers

Answer 1

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]

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​

Answers

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​.

In 2010, the Soufriere Hills volcano on the Caribbean island of Montserrat erupted violently, spewing huge clouds of ash and gases into the sky. How do the volcanic eruptions at the end of the Permian period and the formation of Pangaea, both of which occurred about 252 million years ago, set in motion events that altered evolutionary history

Answers

Answer and Explanation:

Pangaea is the term used to describe the supercontinent that existed millions of years ago, before the continents were spread across the globe as we know it today. The separation of continents occurs due to the rapid convections of the Earth's mantle. These mantle convections increased volcanic activity on the earth, making volcanism very active and causing numerous volcanic eruptions, which increased the concentration of carbon dioxide in the atmosphere, increasing the greenhouse effect and creating a long period of intense global warming.

It was this global warming that altered the evolutionary events on earth, promoting a strong natural selection of plants and animals, which even led to the creation of new species and extinction of old species, in addition to creating a geographical and environmental modification.

La Soufriere Hills volcano is a group of active volcanoes. The volcanic eruptions altered the climatic conditions and led to natural selection.

What is Pangaea?

Pangaea was used to describe the supercontinent that existed millions of years ago before the separation of the continents present now. The rapid convections in the mantle of the Earth caused the shift and drift in the tectonic plates.

The movement of the tectonic resulted in increased volcanic activities that caused numerous volcanic outbreaks resulting in increased carbon dioxide concentration in the environment.

This led to global warming and resulted in a change in climatic conditions. Global warming altered the evolution of the organisms through the process of natural selection and led to the extinction and the introduction of species.

Therefore, volcanic eruptions and Pangaea resulted in environmental and geographical alterations.

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

Answers

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.

Answers

Answer:

In this unit, we will be discussing Latitude as a climatic control. By latitude we are not talking about geographic location. Rather our interest will center on the effect of latitudinal location on the receipt of solar energy at the Earth's surface. To a degree the Greeks were on to the idea when they proposed their Torrid, Temperate and Frigid temperature zones over 2000 years ago.

02. Specifically in this section on Latitude, we are going to cover four topics:

Earth-Sun Relationships. This section will deal with the actual receipt of solar energy at the Earth's surface. The receipt of solar energy is directly related to the relationships which exist between the Earth and the Sun across the year. All of you would recognize the basic relationships. Each day we can see that the Sun "rises" in the east and sets in the west. Most would also recognize that over a 12 month period the Sun "moves" from north to south in our sky. In other words, the Sun not only "moves" from east to west, but also north to south. And how about the fact that days tend to get longer in the northern hemisphere from December 21 to June 21, and then grow shorter from June 21 to December 21? Earth-Sun relationships cause changes in the amount of insolation received day to day and seasonally. And, depending upon the relationship, the amount of insolation changes locationally and through time. The resultant temperatures created due to these changing relationships create pressure differences which are largely responsible for winds. The winds in turn drive the ocean currents and our weather.
