BIO 110 Watershed Lab Report (45) 1. Using chart 1, answer the following questions (6): a) How much land (in square kilometers) in Our Watershed was converted to residential area between 1900 and 1950? b) How many square kilometers were converted to residential area between 1950 and 2000? c) Which natural land cover experienced the most loss from 1900-2000? 2. What type of land use increased in Our Watershed the most from 1900 to 2000? What type increased the second most? (4) 3. Which type of land use produces the most runoff (Chart on Volume of Water)? Which land use produces the least runoff? (4) 4. What was the percent increase in total runoff between 1900 and 2000 into the stream? (4) 5. Discuss how land use contributes to the water quality and overall health of the stream. Given the change in land use from 1900 to 2000, do you think the runoff will continue to increase or not? What do you think the impact of increased runoff would be on the quality of the water in the stream? (7) 6. Apply your knowledge: Based on your observation of Donaldson Run Park, what is the dominant land use surrounding the park and stream? What are the most likely pollutants that could affect this stream? What steps can we take to reduce the harmful effects of storm water runoff? (10) 7. What do the contour lines on topographic maps represent? How are topographic maps used in studying watersheds? (5) The following question requires you to do online research. 8. What is a LID (Low Impact Development) as it relates to storm water management? Provide at least two examples of LID methods used in managing storm water. How do LIDs contribute to water sustainability? (5) Scanned with CamScanner

1. Using chart 1, answer the following questions (6):
a) How much land (in square kilometers) in Our Watershed was converted to residential
area between 1900 and 1950?
Solution
Converted land between 1900 and 1950
33- 13
= 20km2
b) How many square kilometers were converted to residential area between 1950 and 2000?
Solution
58-33
=25km2
c) Which natural land cover experienced the most loss from 1900-2000?
Solution
Grassland and wetland they made a loss of 12km2
2. What type of land use increased in Our Watershed the most from 1900 to 2000? What type
increased the second most? (4)
Solution
The most increased was for the Agriculture having increased from 10km2 to 89km2 making an
increase of 79km2. The second most was that of residential making an increase of 13km2 to
58km2a profit of 45 km2
3. Which type of land use produces the most runoff (Chart on Volume of Water)? Which land
use produces the least runoff? (4)
Solution
Residential
698,000 + 1,958,000 + 2,592,000
= 4,698,000m3
Wetland
45000+59000 +9000
158,000m3
Residential produces the most runoff having a total of 4698000m3 and Wetland producing
158,000m3
4. What was the percent increase in total runoff between 1900 and 2000 into the stream? (4)
Solution
The initial was 8,421,000
The final discharge is 10,293,000
The increase will be therefore,
10,293,000-8,421,000
= 1,87...
