Answer:

As explained below.

Explanation:

A stream is a body of water with water on the surface flowing as in channels, beds, and banks. A stream can also include underground flowing stream and it responds to biological, geomorphological and hydrological biotic factors.

As depending on the locations the longer streams are called rivers and form an important component of the hydrological cycle. Types of streams ecological zones are a Brook, Creek, River, Tributary.

Their sources may be in the form of ice, snow, rain or runoff. The ephemeral stream has a less floe and is generally formed from the rainfed water. Usually of low widths. The intermittent stream is a full flood stream with a high capacity of water and found in alpine sources.

River gradient and age of the river also affects its carrying capacity. As the younger and newer river flowing at the mouth have strong currents, as compared to the middle meandering river that is a mature and old stage of the river that tends to be lower gradient and depository in nature.

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

dlinn [17]

Answer:

$\mathbf{Q_p =682 \ \ ft^3/s}$

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 $t_c = 0.0078L^{0.77} S^{-0.385}$

where;

L = 6870

S = 5/264

$t_c = 0.0078(6870)^{0.77} (\dfrac{5}{264})^{-0.385}$

$t_c =32.34$ min

Since 60 min = 1 hour

32.34 min will be (32.34*1)/60

= 0.539 hour

Lag time $T_l = 0.67\times t_c$

$T_l = 0.67\times 32.34$

$T_l = 21.6678\ min$

The time to peak i.e

$T_p = \dfrac{D}{2}+ T_L \\ \\ T_p = \dfrac{15}{2}+ 21.6678 \\ \\ T_p = 29.168 \ min$

$T_r = \dfrac{T_p}{5.5} \\ \\ T_r = \dfrac{29.1678}{5.5} \\ \\ T_r = 5.30 \ min$

Since D = 15 min is not equal to $T_r$ , then we hydrograph apart from $T_r$ duration lag time.

Then;

$T_p \ ' = T_p + \dfrac{D-t_r}{4} \\ \\ T_p \ ' = 29.168 + \dfrac{15-5.30}{4} \\ \\ T_p \ ' = 31.593$

Now, we need to determine the peak discharge $Q_p$ by using the formula:

$Q_p = \dfrac{484 \times A}{T_p \ '}$

where

484 = peak factor

Recall that A = 475 acres, to miles, we have:

A = 0.7422 mile²

$T_p \ ' = 31.593/60$

∴

$Q_p = \dfrac{484 \times 0.7422}{\dfrac{31.593}{60}}$

$\mathbf{Q_p =682 \ \ ft^3/s}$

Match the energy source in column 1 to its characteristics in column 2

pentagon [3]

Answer:

1 - Nuclear Power (I'm not sure but Nuclear Power is mostly minerals like mercury and that stuff so im not sure)

2 - Oil (I'm not sure either but this must be iot because i did heard that oil may run out in some years)

3 - Hydroelectricity

4 - Solar power

I'm not sure about the first 2 they are probably right but im 100% sure about the last 2 !

Hope I helped

How did this cone of depression in the groundwater form? Group of answer choices an artesian spring flowed upward on all sides t

NISA [10]

Answer:

groundwater is pumped from the well faster than it can flow to replenish what is lost

Explanation:

The cone of depression in the groundwater is formed when "groundwater is pumped from the well faster than it can flow to replenish what is lost."

The pumping of the well, reduces the water level in the well, thereby leading to a gradient shape between encircling aquifer water and the well water. The gradient in turn causes a flow from the encircling aquifer into the well.

During the flow, the water pressures in the aquifer reduce, which eventually form a cone-shaped depression off the well.
