32.5.1. Construction Steps

Try these first

1. 1.

   What does streamflow data represent?

   Hint

   Think about measurements of water flow.

2. 2.

   What are the axes of a Flow Duration Curve?

   Hint

   What two elements are being compared?

3. 3.

   What is the first step in constructing a Flow Duration Curve?

   • Calculate discharge
   • Collect streamflow data
   • Rank data

   Hint

   What do we need to know before anything else?

4. 4.

   True or False: The y-axis of an FDC shows exceedance probability.

   • True
   • False

   Hint

   Consider what different components are plotted on the graph.

5. 5.

   Given streamflow data for a river collected over a year, create a Flow Duration Curve for it. Explain your steps involved in detail.

   Hint

   What elements do we consider for proper analysis?

6. 6.

   How would changes in land use, such as urbanization, affect the Flow Duration Curve for a river?

   Hint

   Think of how cities manage stormwater and how that affects river flow.
