The article gives an assessment of the hydrological regime on the River Tesha sector . The assessment was obtained during the pre-project study of the object and allows making project decisions on clearing the riverbed. The River Tesha Basin has been well studied in the past. However, there was no data based on long-term observation of the river's hydrological regime parameters in the area under consideration; hence, the authors performed calculations for data recovery by interpolation between existing hydrological posts, as well as for obtaining their representative series and determining their hydrological characteristics. Correlation between changes in flow rates and water levels in the river was found, as well as between the riverbed morphological parameters (depth, width, cross-section area) and its hydraulic characteristics (flow rate, flow rates). The completed assessment of the hydrological regime makes it possible to forecast river flooding at high water levels as well as flooding of the surrounding area, and to make project decisions thereafter, including the identification of flooding areas, the dump sites choice, these sites functioning period f that depends on when and for how long they will be flooded during the year.
