WitrynaTo calculate both streamflow and discharge during a flood event, we need to use some basic tools and equations. One method for measuring streamflow during a flood event involves using what’s called a current meter. This device looks like an underwater fan with rotating blades that spin as they’re pushed by the moving water. Witryna60. Project: Measuring Streamflow. Purpose of the project: Apply numeric integration techniques to a real-world problem. How do you measure streamflow? The basic idea is simple: it is area times velocity. For example, suppose you had a river that was 20 20 feet wide, 3 3 feet deep, and had water moving at 2 2 feet per second. Then we multiply ...
