At the conclusion of this course, the student will

·        Be able to determine the value for runoff coefficient for a drainage area with known land use, SCS soil group, and approximate surface slope.

·        Be able to find the rainfall intensity for specified storm duration and return period at a specified location if given an I-D-F table or graph for that location.

·        Be able to estimate the overland flow travel time for a drainage area using the Manning Kinetic Equation.

·        Be able to estimate channel flow travel time using Manning’s Open Channel Flow Equation.

·        Be able to estimate peak runoff rate from a drainage area using the Rational Method.

·        Be able to use Method I and Method II as outlined in this course to calculate design diameter and slope for a length of storm sewer between two successive manholes.

·        Be able to determine the velocity and flow rate in a circular pipe flowing partially full if enough information is available to calculate the full pipe velocity and flow rate.

·        Be able to put together the above skills to carry out the overall hydraulic design of a length of storm sewer between two successive manholes.

·        Be able to use Excel to make storm sewer hydraulic design calculations for lengths of storm sewer between successive manholes.
