Summary: | Highway Drainage Concepts for Design is an application-oriented training course covering concepts, policies and design standards for the design of efficient roadway drainage system. The course is based on Chapter 10 of PennDOT Design Manual 2, the PennDOT Drainage Manual, and the Federal Highway Administration’s Urban Drainage Design Manual (HEC-22), and introduces fundamental hydrologic and hydraulic concepts and provides practical instruction in design of pavement drainage and conveyance systems. Through presentations, workshops and design examples, participants will learn how to configure highway drainage systems and implement procedures for highway drainage design including evaluation of gutter flow, determining grate and inlet capacities, and overall sizing of stormwater conveyance networks.
|
Learning Outcomes: | Upon completion of the course, participants will be able to:
1. Perform a preliminary drainage system layout.
2. Apply the Rational Method for inlet and storm sewer conveyance system design.
3. Compute gutter flow quantities and relate them to the spread of stormwater on roadway surfaces.
4. Assess inlet capacities and efficiencies for various grate and inlet types.
5. Determine appropriate inlet spacing.
6. Determine appropriate pipe sizes for storm drain conveyance systems.
7. Understand the basis for the hydraulic grade line analysis of piped conveyance system.
