In hydrology, a rating curve is a graph of discharge versus stage for a given point on a stream, usually at gauging stations, where the stream discharge is measured across the stream channel with a flow meter. Numerous measurements of stream discharge are made over a range of stream stages. The rating curve is usually plotted as discharge on x-axis versus stage (surface elevation) on y-axis. The development of a rating curve involves two steps.
Method for calculating monthly ecological base flow of frozen river in semi-arid region
The application discloses a kind of semi-arid region frozen river monthly ecological base flow calculation method, with river section geometry and wet week response as basis, coupling typical aquatic organism habitat water depth constraint in different periods, and combining long-term hydrological sequence and monthly rating curve back propagation flow, form monthly output, explainable, reproducible ecological base flow sequence, especially for frozen period water level-flow relationship distorted problem gives independent processing scheme;The application relates to the field of ecological hydrology and river ecological restoration technology.Semi-arid region frozen river monthly ecological base flow calculation method, biological water requirement is upgraded from single threshold to stage-month threshold H2 (m) throughout the year, avoid unreasonable constraints on non-resident months for migratory species, improve ecological suitability;Non-frozen period uses monthly rating curve back propagation flow, reduce the system deviation that month difference is regarded as water level difference, improve back propagation accuracy and month scale availability.
