Document Summary
Lab #5 rating your river: relating stream discharge and water height. In hydrology, it is important to understand the relationship between stream discharge and water height. Scientists use a rating curve in order to demonstrate this relationship where discharge is plotted on the x-axis and stage on the y-axis. Rating curves are important tools in order to properly monitor streamflows. In this lab activity we will produce a rating curve for the. San diego creek and san joaquin marsh in irvine, california. Stream stage is the height of water above some arbitrary point i. e. the water level. Discharge is the volumetric flow rate or the volume of water moving down the stream. A r ating curve is used to monitor streamflow and is plotted using discharge versus the. The thalweg is the deepest part of the stream. stage at any given point on a stream.
