3. A small watershed with 2-yr 24-hr rainfall depth of 3 inches has a maximum hydraulic distance of 1,600 feet. Of which sheet flow occurs for first 95 feet while the concentrated sheet flow occurs for the rest of the hydraulic travel distance. Sheet flow section of the watercourse has dense grass with Manning's constant (n) of 0.24 with slope 0.01. While the concentrated sheet flow section of the watercourse has average velocity of 1.5 ft/sec. Determine Time of Concentration for the watershed for 2-yr 24-hr rainfall. (20 pts)
