This course will introduce you to normal requirements for design of surface and subsurface drainage systems for residential, commercial, institutional and industrial areas. You will learn about predesign investigations, environmental considerations, hydrologic studies, hydraulic design considerations, erosion control and subsurface drainage. References and a bibliography are provided that will allow you to advance beyond this introductory course and begin to address area drainage issues or real projects in your company or agency. Course Outline 1. Introduction 2. Hydrology 3. Hydraulics 4. Erosion Control and Riprap Protection 5. Subsurface Drainage Appendix A: References Appendix B: Notation Appendix C: Bibliography This course will give civil engineers and others an introduction to the hydrological and hydraulic design of area drainage plans, including hydraulic structures, erosion control and riprap design.

Learning Objectives

• Learn about field investigations needed before starting drainage system design
• Learn how selection of design storm magnitudes depends on the protection sought, the type of construction contemplated, and the consequences of storms of greater magnitude than the design storm.
• Learn about the design of roadway culverts to accommodate rainfall conditions.
• Learn the approach to hydrologic analysis of an area for given rainfall conditions.
• Learn about the hydraulic design of drainage channels and structures to accommodate rainfall.
• Learn about erosion control and riprap protection for drainage channels and structures.
