River channel forms

Description

This program analyzes the dynamic nature of rivers and the relationship between their forms and processes. It examines the various functions a single river needs to perform, and shows how to measure river form and process, relate the two, and synthesize several attributes of the form of a river channel. It examines the differences between low and high flow, and explains how to calculate the quantity and velocity of water transport and how to attempt to measure the amount of bed-load. It compares bank full and low flow and upstream and downstream discharge, shows how man's intervention has solved a low water problem, and asks students to try to deduce what will occur during a flood.
