Hydraulic Analysis
The drainage system was designed by taking advantage of the existing topographic conditions. There is an arroyo on the south-west section of the project site; the proposed improvements include directing all the runoff to this natural depression. The new drainage system will be handling the runoff generated by the roadway improvements and draining into the natural depression. Any drainage structure is sized according to the probability of occurrence of an expected peak discharge during the design life of the installation.
A ponding area was also designed in order to retain runoff created by the road. Improvements for the road were also proposed. The road has a slope of 2%; it was conclude a ditch in the median is the best option in order to drain the runoff generated by the roadway. The ditch will be located before the two roads merge. To design this element, the discharge the road will create is to be known. Ditches were sized to handle the peak runoff. The design was made by using all of the standards for a triangular channel.
In order to reduce the runoff accumulated in the north-east area of the project, culverts are to be included. The culverts will take the water under the roadway from the east side to the southwest where the arroyo is located
