Design of Urban Water Management Structures (edX)

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.

Syllabus

Week 1: Rainfall temporal and spatial variation, design rainfall and hydrologic risk
Week 2: Runoff using Rational Method, storm sewer design
Week 3: Detention storage design, SCS CN method
Week 4: Hydrographs, SCS triangular and curvilinear unit hydrographs
Week 5: Superposition, computing runoff hydrographs from unit hydrograph theory

Prerequisites

• An undergraduate course in hydraulics or fluid mechanics
• CE59700.1 Analysis and Design of Water Distribution Systems and CE59700.2 Design of Sanitary Sewer Systems would be highly desirable.
