PHYSICAL MEASUREMENTS from NEW HOPE CREEK, ORANGE CO, NC on 23 July 2013 by Nia Swain

Our data for today is that we did measurements of the stream flow to see any differences in the water by rainfall or any other types of substances that may have gotten into the water. The measurements of the stream flow going upstream was 46′ and 8″. while the measurements for going downstream was a little different 41′ and 2″. The turbidity measurements as an average: 85.1; Water Temperatures Average: 26 Celsius. Another thing we did today was do a Visual Stream Assessment where we look at the stream to see if there was anything usually or unusual we saw. We first looked at the weather: overcast; water odors: normal; water color/appearance: brown/muddy; algae: covers substrate.  The channel conditon: 6; bank stability:8; nutrient enrich.: 4; pools: 7; riffle embedd.: 6.5; riparian zone: 10; water app.: 7; instream fish cover: 10; invertebrate habitat: 7; and canopy cover: 10. These scores we chosen because we all thought as a group based on what we cpuld tell by observing, & get a sense of what the water felt like.

 

PHYSICAL MEASUREMENTS from NEW HOPE CREEK, ORANGE CO, NC on 15 July 2013 by Jesus

Visual Stream Assessment:

  • The weather in the past 24 hours has been overcast.
  • Today, it was sunny/clear.
  • The water smelled n0rmal.
  • The water was brown/muddy and contained some foam/suds.
  • Minimal algae growth was detected.
  • Mud and boulders were the dominant substrates in the water.

Site Observations:

  • 150 ft: Most of the creek was covered with a shadow. Lots of foliage could be seen on either side of the creek. The trail on one side of the creek took away from some of the plant cover.
  • 300 ft: The water was audible. Less of the creek was covered in shadow. One side of the creek had some exposed areas with no plants.
  • 450 ft: The water was a lot louder and many boulders were present. At this point, the creek meandered a bit.
  • 600 ft: There were many boulders in the area. Some pools were visible. One of the banks was very rocky.

Assessment Scores:

  1. Channel condition- 7.25
  2. Bank stability – 8.2
  3. Nutrient enrichment – 8.75
  4. pools – 7
  5. riffle embeddedness – 10
  6. Riparian zone – 10
  7. Water appearance – 5
  8. Instream fish cover – 5
  9. Invertebrate habitat – 6
  10. Canopy cover – 10

Turbidity – 3 separate tests

  1. 86 cm
  2. 64 cm
  3. 70.5 cm

Water temperature (fahrenheit) – 2 separate tests

  1. 78
  2. 72

Stream Flow: (A L C)/T

A: Avg. Cross- Sectional Area

Transect #1 Interval Width Depth
A-B ~10ft 20 3/4 in
B-C ~10ft 31 in
C-D ~10ft 12 1/2 in
D-E ~10ft 11 in
Total 75 1/4 in
Average Depth 18.81 in/ 1.57 ft

Tot width x avg depth = Avg. cross-sectional area

43.2ft  x 1.57ft = 67.73 ft^2

Transect #2 Interval Width Depth
A-B 9ft 21 in
B-C 9ft 23 3/4 in
C-D 9ft 19 1/2 in
D-E 9ft 11 in
Total 36ft 75 1/4 in
Average depth 18.81 in/ 1.57 ft

Tot width x avg depth = Avg. cross-sectional area

36ft x 1.57ft = 56.52 ft^2

Avg cross sectional area of both transects: (67.73 ft^2 + 56.52ft^2)/2 = 62.125 ft^2

L: Length of Stream Reach = 25ft

C: Coefficient = .85

T: Travel Time

Trial #1: 42.50 sec
Trial #2: 38.7 sec
Trial #3: 43.4 sec
