About this courseSkip About this course
Detention storage structures and storm sewer systems are used to store and transport rainfall-runoff through open ditched and underground pipes.
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.
