Experience of mathematical modeling of a hydrograph of river flow (by the example of the river Mesha in the territory of the Republic of Tatarstan)

Mathematical methods in hydrology have been used for a long time, however, the construction of complex models implemented in the Hydrograph software package is a relatively recent achievement, actively used in scientific research. Standard meteorological information is used as the meteorological input to the model, which simplifies the preparation of input data. The complex describes all the processes of runoff formation that make up the terrestrial hydrological cycle.
