Urban Drainage Design (3-Day)
Instructor-led Training (ILT)
TRAINING LEVEL: Intermediate
CLASS SIZE: Minimum: 20 Maximum: 30
This course provides a detailed introduction to urban roadway drainage design. Design guidance for solving basic problems encountered in urban roadway drainage design is provided. The topics are hydrology including rational equation, soil conservation method, regression equations, and synthetic hydrographs; and highway drainage including gutter flow, roadway inlet interception, storm drain systems, energy and hydraulic grade lines, detention ponds, and stormwater management.
The 4-day course includes the basic 3-day course, plus presentation of the 1-day course FHWA-NHI-135028 Stormwater Pump Station Design.
Upon completion of the course, participants will be able to:
Determine runoff (peak flows and volumes) from urban watersheds
Apply basic hydraulic principles to urban drainage design
Perform roadway drainage designs using various roadway inlets
Size and/or analyze storm drain conveyance systems
Establish the energy and hydraulic grade lines for storm drains
Design and/or analyze detention basins
Perform hydraulic design of pumping stations (with optional day four)
Highway designers with limited experience in drainage design, but familiar with mathematical concepts such as algebra and geometry and have some working background in hydrology and hydraulics.
