Flood Routing Notes

About this Chapter

This document contains the complete study material for Chapter 8: Flood Routing. Flood routing is essential for determining the timing and magnitude of a flood wave as it travels down a river channel or through a reservoir.

In this chapter, students will learn about hydrologic channel routing using prism and wedge storage. Key methods covered include the Muskingum method for channel routing and Clark’s method for instantaneous unit hydrographs (IUH) using time-area histograms.
