Loose Gravel

QUESTION 6 Determine whether the materials shown below would have high or low Vesicular Volcanic Igneous Rock

QUESTION 7 If a material is porous, it ____.
will be permeable as well.
will be impermeable.
may be permeable or impermeable,

QUESTION 8 Watch this video on Darcy's taw and answer the corresponding questions. Additional information on Diarcy's Law is in the Lab 9 Information Packet.

According to the video, what is the driving force of flow in ground water,

QUESTION 9 The sketch below, similar to the one seen in the video, outlines the variables in Darcy's law, Based on this information if H_A = 100 cm and H_B - 40 cm, what is ΔH, (answer will he in cm)

QUESTION 10 Utilizing the information in the sketch below calculate the variable k, hydraulic conductivity, for sand. (answer will be In units of cm/s)

QUESTION 11 Utilizing the information in the sketch below calculate the variable k, hydraulic conductivity. for gravel,

QUESTION 12 Based on your last two answers, if you were tasked with containing a recent oil spill would you be more concerned of contaminants spreading if they were spilled over sand or gravel? Explain your answer using principles from Darcy's Law.

QUESTION 13 Imagine you sample the subsurface material in your backyard in an attempt to figure out how quickly the local groundwater is flowing. You place this material in a perrnearneter with a radius of 3 cm and set up the experiment with a hydraulic gradient of 1. If you then run the experiments and collect 50 ml of water in 20 seconds, what is the hydraulic conductivity of the material?

QUESTION 14 Completethe table below using the elevation of the ground surface and the depth to the water table in each well to calculate the elevation of the water table at each location on the map (answers should be to the hundredth rn, i.e. two decimal places)!

QUESTION 15 Why do natural springs form?

QUESTION 16 Based on the well locations and elevation of the water table what orientation would you draw the groundwater contours for the surface of the water table (not the depth to water)?

QUESTION 17 What direction is the ground water flowing?

QUESTION 18 A dry well will always result whenever the base of the well is above the water table.

QUESTION 19 Groundwater may be flowing into the Fenton River (water table slopes toward it), a situation known as a gaining stream. Alternatively, your data may show a water table that slopes away from the river, indicating that water may he flowing from the Fenton into the groundwater system (a basing stream). On the basis of your data, is the Fenton River a gaining stream or losing stream?

QUESTION 20 A groundwater consulting company has created a grid showing depth to water (NOT elevation) values in feet below a flat ground surface What is the direction of groundwater flow at point A? (Assume the top of the page is North)

QUESTION 21 A groundwater consulting company has created a grid showing depth to water (NOT elevation) values in feet below a flat ground surface What is the direction of groundwater flow at point B?

QUESTION 22 You have been able to map out both the topographic contours (black lines) and the elevation of the water table (light blue lines). Imagine you are putting in wells for land owners, and need to determine how deep to drill the well to reach the water table.

QUESTION 23 How deep (to the nearest 10') do you need to drill a well to reach the top of the water table at location A?

QUESTION 24 How deep (to the nearest 10') do you need to drill a well to reach the top of the water table at location B?

QUESTION 25 How deep (to the nearest 10') do you need to drill a well to reach the top of the water table at location C?

QUESTION 26 How deep (to the nearest 10') do you need to drill a well to reach the top of the water table at location D?

QUESTION 27 ldentifiy the components of the groundwater system in the diagram below labeled A- ______, B-_______, C-______ D-_______, E- ________, F-________.

QUESTION 28
a) Do you think most of the rivers and streams on the East Coast of the U.S. are losing or gaining streams? Why?

b) Where is one place you might find the other type of stream? Explain.

QUESTION 29
Is groundwater a renewable or nonrenewable resource? Explain your answer.

QUESTION 30

Using what you have learned, and information from this website list three potential sources of groundater contamination. Now select one - what can be done to reduce or eliminate the risk?
