Calculations:
Activity 1.
Sinuosity:
Curvy distance (cm) / Straight distance (cm) = sinuosity (no units)
___________ / ____________ =
Both the curvy and straight distances are measurements taken from the stream formation in the stream table. Please refer to Activity 1 for more details.
Velocity
Distance traveled (cm) / Time it takes to travel (s) = Velocity (cm/s)
___________ / ____________ =
The distance it takes a small piece of paper to travel downstream divided by how long it takes to get downstream is the velocity. Refer to Activity 1 for more details.
Relief
Highest elevation (cm) – Lowest elevation (cm) = Relief (cm)
___________ – ____________ =
By subtracting the highest elevation of the stream and the lowest elevation of the stream from each other, the relief can be calculated. Please refer to Activity 1 for more details.
Gradient
Relief (cm) / Total distance (cm) = Gradient (no units)
___________ / ____________ =
By dividing the relief by the total distance of the stream, the gradient can be calculated. Please refer to Activity 1 for more details.
ACTIVITY 2
Sinuosity
Curvy distance (cm) / Straight distance (cm) = sinuosity (no units)
___________ / ____________ =
Both the curvy and straight distances are measurements taken from the stream formation in the stream table. Please refer to Activity 1 for more details.
Velocity
Distance traveled (cm) / Time it takes to travel (s) = Velocity (cm/s)
___________ / ____________ =
The distance it takes a small piece of paper to travel downstream divided by how long it takes to get downstream is the velocity. Refer to Activity 1 for more details.
Relief
Highest elevation (cm) – Lowest elevation (cm) = Relief (cm)
___________ – ____________ =
By subtracting the highest elevation of the stream and the lowest elevation of the stream from each other, the relief can be calculated. Please refer to Activity 1 for more details.
Gradient
Relief (cm) / Total distance (cm) = Gradient (no units)
___________ / ____________ =
By dividing the relief by the total distance of the stream, the gradient can be calculated. Please refer to Activity 1 for more details.
