This course consists of stormwater calculations associated with designing a bioretention basin for a suburban site. 

Topics include the following: 

• Conceptual design using a bioretention case study 
• Calculating total storm volume,  
• Calculating basin storage,  
• Determining peak flow rates,  
• Pipe sizing, and  
• Basic bioretention design. 

The main objective of this course is to provide you with an introduction to basic stormwater calculations associated with designing a bioretention basin for a suburban site. 

• Demonstrate how to calculate total stormwater volume from a design storm (using the Simple Approach and the Curve Number Method). 
• Describe peak flow rates and how to size for them (using the Rational Method and Manning’s Equation).
• List the basic considerations of bioretention sizing and design.
