  1. You have a 5 acre commercial development, where flow drains into a gutter. Assume that the travel time is 15 mins. The rainfall intensity can be determined by the following equation: i=10t-0.4.

For the curb and gutter have the following design parameters: n = 0.015, cross slope of 40:1 and longitudinal slope is 3.0%.

  1. Determine the gutter flow depth, curb design depth and spread necessary to contain the 10 year peak flow.
  2. Determine the size of the catch basin for both submerged and unsubmerged flow conditions.
  1. Determine the area of the watershed, which drains to a road with a curb and gutter. The roadway information is as following: spread of flow is 10 feet, roughness is 0.013, longitudinal slope is 0.008, cross slope is 30 and curb height is 5 inches. The runoff coefficient time the rainfall intensity is 5.5 inches/hr.
    1. Find the Flowrate in the road?
    2. Determine the area of the watershed?
