Introduction to Flood Routing Methods

COURSE NO: C04-053
Introduction to Flood Routing Methods
Course Highlights

This engineering online PDH course covers the basic concepts, calculation procedures, and example calculations for flood routing.


Flood routing is one of the key elements of a watershed hydrological model.  Stream channels, floodplains, and reservoirs can have a significant impact on the delivery of water to any location along a stream network.  Flood routing can be used to determine the magnitude of the peak discharge, the time of the peak discharge, depth and extent of flooding, and environmental factors such as stream bank erosion, floodplain scour, sediment transport, and deposition.


This 4 PDH online course is intended for civil, environmental, hydrological and stormwater management engineers and other technical personnel who are interested in learning more about flood routing.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understading the differences between hydrologic flood routing and hydraulic flood routing methods
  • Understading the difference between translation effects and storage effects on flood wave movement down a stream system
  • Familiarizing with elevation-storage and elevation-discharge relationships for reservoirs
  • Familiarizing with elevation-discharge and elevation-storage relationships for channel reaches
  • Familiarizing with elevation-discharge hydrographs to reservoirs or channel reaches
  • Learning how to make reservoir routing and channel routing calculations using the storage-indication routing method
  • Learning how to use the Muskingum method for channel routing calculations
  • Learning how to use the Muskingum-Cunge method for channel routing calculations
  • Learning how to use the Muskingum method for channel routing calculations with meandering streams
  • Familiarizing with the effects of baseflow on routed flows
  • Familiarizing with the effects of transmission losses on routed flows
  • Familiarizing with routing through tide gates and dikes
