Question

Can someone answer for me please.

Maps application.

The citizens of Hazard County have become aware of contamination in Mill Stream, a tributary of the Clearwater River. They are concerned that this change in the quality of the river water will affect the river's ecosystems.

You will be sampling water from Mill Stream and three of its tributaries to determine if any of them are the source of the contamination. If the source can be discovered, remediation may be possible so that the water quality can be improved before it enters the Clearwater River.

To begin to determine the source of the contaminant, you must collect samples from several sites along Mill Stream and each of its three tributaries. You will perform field tests on the samples you collect, and you will also collect further samples to be tested in a laboratory.

Before you set out to collect your samples, you should determine the distance you will travel and the easiest way to complete the route. Once you know the length of your route and how long it will take you to collect samples and perform field tests, you can determine the total time it will take you to complete the collection of samples from all 12 sites. You will begin at the campground near Maverick Plateau.

To complete your work, use the links on the left. These resources will help you

·         Identify items from map legends

·         Understand map scale

·         Read topographic maps

·         Calculate rate, distance, and time problems

·         Determine the distance between points

·         Calculate route distance

Part A - Reading topographic maps

Using what you know about topographic maps, identify the elevation of 6 of the 12 sites on the Plateau Map below. Review the information at the Reading Topographic Maps link if you need a refresher on how to read topographic maps.

Drag the appropriate labels to their respective targets.

Taking into consideration what you know about water quality and topographic maps, you will conduct field tests of the 12 sites. Use all your tools and expertise to determine the correct answers to the questions below. Review the map above again, or click the Plateau Map link, and note the scale at the bottom. Once you return and analyze your data, it can be viewed for each site on the map at the Plateau Map link. Click on each site to see the results and to help you determine where to focus in future testing. Review the Water Quality page for more information on water testing.Part B - Performing field tests

Drag the appropriate answers to their respective questions.

Now you will use your topographic knowledge to answer a few more questions that field geologists often think about. These skills are important for navigating terrain and assessing many types of hazards.

Part C - Calculating gradient: Spider Run

Gradient (or slope) is calculated as the change in elevation (feet) divided by the distance traveled (miles). Using the map at the Plateau Map link, what is the approximate gradient of the trail at Spider Run? Note the length of the trail runs from Site 4 to Site 5.

2. 140 feet/mile

3. 920 feet/mile

4. 280 feet/mile

Part D - Calculating gradient: Lye Run

Gradient (or slope) is calculated as the change in elevation (feet) divided by the distance traveled (miles). Using the map at the Plateau Map link, what is the approximate gradient of the stream at Lye Run? Assume the trail ends at the top of the stream bed (blue line).

Choose from part(1,2,3,4)

1. Knight's Run

2. Lye Run

3. Spider Run

4. Mill Stream

Part J - Campground and school elevations

About how much higher is the campground than the school?

Choose from part(1,2,3,4)

1. 200 feet

2. 80 feet

3. 20 feet

4. 120 feet

Part K - Clearwater River

What is the approximate elevation of Clearwater River?

Choose from part(1,2,3,4)

1. 640 feet

2. 700 feet

3. 760 feet

4. 800 feet

Part L - Using the map

Refer to the Plateau map again. You start in Hazard City at the intersection of the primary highway and the secondary highway. You drive .8 miles to the south and park your car. You get out of the car and hike due east .25 miles. You then follow the contour line to the north/northeast just under .4 miles. Where are you?

Explanation / Answer

Part A:

Site 1: 890

Site 2:850

Site 5:924

Site 6:858

Site 9:960

Site 10:878

Part C:

the gradient of spider run will be 280 feet/mile

Part D:

the gradient of lye run will be 226 feet/mile

Part E: Lye run will be steepest of all because from the map we can see that the contour spacing is narrow that indicates steeper changes in gradient whereas in all other runs the spacing between contours is broad.

Part F: If we are hiking from the bottom of Spider Run and along the river and toward the plateau it will be towards east.

Part G: The Lye stream will flow towards South because we can see on the map that the contours are decreasing from south to north and we know that a river flows from a higher elevation to lower elevation.

Part H: the highest elevation will be exactly 1024feet as we trail to the top of Maverick plateau.

Part I: Mill stream begins at highest elevation because we can see from the map that it is a tributary of Clear river and other streams joins the Mill stream at later stages

Part K: elevation of Clearwater River is approx 760 feet

Part L: we are exactly at site 2.

The gradient of spider run will be 280 feet/mile
