Fantastic news! We've Found the answer you've been seeking!

Question:

Using the following chart answer the following:

Determine the average value for the water level (m) and discharge (m³/s). [1 mark]
Assuming that the stream has a semi-circular cross section whose radius is equal to the water level:
1. Estimate the corresponding cross-sectional area. [2 marks]
2. Using the measured discharge (Question 2(a)(i)) together with the cross-sectional area (Question 2(a)(ii)(1)), estimate the average flow speed of the stream. [3 marks]

By adjusting the date parameters, ensure hydrometric data is available for the precipitation events identified in Question 1(a). For these events:
1. Determine the peak value for the water level (m) and discharge (m³/s) as well as the corresponding time. [1 mark]
2. Assuming that the stream has a semi-circular cross section whose radius is equal to the peak value for the water level:
  1. Estimate the corresponding cross-sectional area. [2 marks]
  2. Using the measured peak discharge (Question 2(b)(i)) together with the cross-sectional area (Question 2(b)(ii)(1)), estimate the peak flow speed of the stream. [3 marks]
3. Provide a screenshot of hydrometric data used - just the graph. [-5 marks for failing to provide the screenshot.]
Compare average and peak scenarios (for the chosen event) as follows:
1. Divide the peak water level by the average water level. [1 mark]
2. Divide the peak discharge by the average discharge. [1 mark]
3. Divide the peak flow speed by the average flow speed. [1 mark]
4. If the stream's kinetic energy is proportional to the square of the flow speed, how much more energetic is the stream at its peak versus the average scenario?
