Analysis methodology for the relationship between the water flow and river levels by determining the dependence

Abstract

The article contains all the available data on average monthly discharges and water levels for the rivers under study, that provided the background for the hydrological series of these characteristics which are found to be in a close stochastic connection. Linear regression equations connect the average month­ly discharges and water levels in the rivers under study. They also provide for the graphs of the relationship between the considered values, and the bounda­ries of their confidence intervals were calculated and constructed. From these dependences, it is possible to determine the average monthly discharge or wa­ter levels in the studied rivers, owning only one set of characteristics. It can also be a picture of regular channel processes, since the distribution of points on the graphs is within the normal range and is attributed to natural rivers processes.
