Question

Depth-Area-Duration curves of precipitation drawn as a

• A. Minimizing envelopes through the appropriate data points
• B. Maximizing envelopes through the appropriate data points
• C. Best fit mean through the appropriate data points
• D. Best fit mean straight lines through the appropriate data points

Hint:

For accurate modeling of precipitation events, ensure that the envelopes are minimized to capture the most extreme values.

Answer 1

The Correct Option is A

Depth-Area-Duration (DAD) curves are used in hydrology to represent precipitation events. These curves are typically drawn by minimizing the envelopes through the appropriate data points to estimate the depth of precipitation corresponding to a given area and duration. This method helps in defining the boundary limits of the rainfall event more accurately.
