A watershed consisting of heavily wooded and grassland area drains into a culvert under a roadway. The total area of the watershed is 310 acres. The 10-year runoff coefficient has been determined to be 0.36. The 10-year and 100-year rainfall intensities have been determined to be 1.2 in/hr and 1.94 in/hr, respectively. Determine de 100-year runoff coefficient and the 10-year and 100-year design discharges to be conveyed by the culvert under the roadway.
