Flood routing and hydrograph generation (see Part 630 Hydrology, chapter 16, 2007) form the key elements of a watershed hydrologic model. Stream channels, flood-plains, and reservoirs can have a significant impact on the delivery of water to any location along a stream network. Flood routing impacts the magnitude of the
Flow routing is a mathematical procedure for predicting the changing magnitude, speed, and shape of a flood wave as a function of time at one or more points along a watercourse (waterway or channel).
Know the differences between hydrologic flood routing methods and hydraulic flood routing methods. Know the difference between translation effects and storage effects on flood wave movement down a stream system. Be familiar with elevation-storage relationships for reservoirs.
Flood routing is the technique of determining the flood hydrograph at a section of a river by utilizing the data of flood flow at one or more upstream sections. The
It describes methods to estimate flood magnitude, including the rational method for small catchments, empirical equations, flood frequency studies, and the unit hydrograph technique. It also covers flood routing through channels and reservoirs, and applications such as flood forecasting and reservoir design.
This document discusses hydrologic routing techniques used to predict changes in the shape of a hydrograph as water moves through rivers and reservoirs. Key points include: 1) Hydrologic routing models streamflow and the movement of flood waves through channels and reservoirs.
1 sty 2015 · Flood routing is the description applied to this process. It is a procedure through which the variation of discharge with time at a point on a stream channel can be determined by consideration of similar data for a point upstream.
