WebThe System Curve. A fluid flow system is characterized with the System Curve - a graphical presentation of the Energy Equation. The system head visualized in the System Curve above is a function of elevation - or the static head and the major and minor losses in the system and can be expressed as: h = dh + hl (1) where. h = system head (m) WebA "rating curve" is a mathematical tool used to predict streamflow based on stage height. Hydrologists develop a rating curve for a site after recording a series of area and velocity measurements of the stream at different stages. This allows them to predict streamflow with only stage height measurements.
