“…Surface runoff hydrographs from subcatchments serve as crucial input functions that form the runoff hydrographs for urban catchments of varying scales, configurations, and complexities [ [5] , [6] , [7] , [8] , [9] ]. Methods for modelling surface runoff should comprehensively consider a multitude of factors and specific characteristics of the subcatchment, including its configuration [ [10] , [11] , [12] , [13] ], absolute dimensions [ 14 , 15 ], slope distribution at the subcatchment's area [ 16 , 17 ], surface cover types and their spatial distribution [ 18 , 19 ], correlation between the total and effective imperviousness [ 2 , 4 , 20 , 21 ], infiltration properties of soils [ 11 , [22] , [23] , [24] ] etc. Errors at this initial stage of modelling inevitably and often significantly impact the subsequent modelling of the entire stormwater drainage system [ 25 , 26 ].…”

“…The quality of hydraulic modelling of stormwater systems on urban areas depends on an adequate and representative collection of three main groups of input data. The first group consists of the climatic data about rainfall parameters in the form of dependences of rainfall intensity on its duration and frequency [Banaszkiewicz et al, 2009;Zhuk et al, 2021]. The second group contains the data about the distribution of coverings at the runoff catchment, about soil types, as well as the features of the relationships between subcatchments and stormwater network, which can be represented as a functional dependence between total and effective imperviousness [Lee & Heaney, 2003;Zhuk et al, 2020b].…”

Broad-crested weirs (BCW) are commonly used elements of stormwater systems and different open-channel hydraulic structures. Specific features of stormwater drainage channels are small width, low flow depths and, accordingly, small overflow heads at weirs. Dependences of the discharge coefficient of narrow (b = 0.224 m) rectangular sharp-edged broad-crested weirs with vertical walls, threshold height of 0.05 m and threshold length of 0.05-0.2 m were obtained experimentally. The experimental values of the discharge coefficient were approximated by the power-law functions of relative length of the weir. At large values of the relative length of the threshold (L/h> 10), for all weirs was obtained the same tendency of decreasing the discharge coefficient with increasing L/h ratio that can be explained by the enlargement of the hydraulic friction along the weir with increasing L/h ratio.

The tendency of increasing the average annual temperature causes a significant violation of the water balance of territories and water bodies as a result of a significant increase in water losses due to evaporation. According to the estimates of [Information and Analytical Report, 2020] under Ukrainian climate conditions, the growth of the average monthly temperature by 1 °C causes an increase in total evaporation by about 9%. Thus, the total water evaporation from the territory of Ukraine in 2020 was 40−45 km 3 per year higher comparing with the corresponding value in 1990, which translates into an average growth of 1.7−1.9% annually. In many regions of the world, the evaporation layer significantly exceeds the depth of the precipitation layer. Compared to Ukraine, where the intensity of evaporation from water bodies in summer is in the range of 1−4 mm/day [Rudakov et al., 2017], in countries with hot and dry climates, this value reaches 8−10 mm/day and more [
