WebThe measurement of discharge can be an average or a sum total. If you choose an average it should be based on a minimum of five measurements across the stream. If a sum total approach is preferred … WebA distribution is a mathematical formula that represents the variability of the times. Most time-based events can be approximated with a distribution. During the simulation, time values are selected from the distribution, allowing the model to portray the type of randomness that the real ED would experience. WebDischarges of rivers, streams and canals can be measured by following methods: 1. Area Velocity Method: This is the direct method of computing the discharge in a stream by measuring its velocity and area of flow.
