In this course, we will:

- Learn about spatial distribution of rainfall, perform statistical analysis, fit different distributions to the data, and calculate design rainfall.

- Learn to estimate runoff using the rational method and time of concentration, and use the SCS-CN method to determine the time distribution of runoff. Unit hydrograph theory and computation of storm hydrographs will be covered.

- Use regulations to design storm sewer systems using EPA-SWMM.

- Compute storage volumes for detention storage structures.

What you'll learn

- Determine design rainfall and calculate runoff using rational method, SCS curve number method and unit hydrograph theory.

- Calculate stormwater flows.

- Analyze and design storm sewer systems and detention storage volumes by rational method.

- Identify, formulate, and solve complex engineering problems.
