**Problem 3.4 (page 115):** 

A large agricultural watershed has a longest flow path length of 2300 feet, a slope of 0.2%, a composite curve number of 75, and a runoff coefficient of 0.16. Estimate the time of concentration using the SCS Lag equation and the FAA formula, respectively.

**Graph Explanation:**

The image includes a scale diagram marking the distance in feet along the flow path. The scale has three points: 0 feet, 1000 feet, and 2000 feet, indicating intervals along the flow path length up to 2300 feet.
