Webb29 jan. 2024 · Twenty-eight rainfall-runoff events were selected for the study, and were delimited by periods of 48 h when rain intensity did not exceed 1 mm·h −1; in addition, the events were definitely selected if the maximal rainfall amount was more than 10 mm and the peak flow more than 1 m·s −1. Table 1 shows their main characteristics. Webb20 juli 2024 · The formulation of the SCS-CN method begins with the water budget expression, stated in depth units, That is, rainfall ( P) is runoff ( Q) plus losses ( F ). We also require the potential maximum retention (or infiltration), S. The ratio of actual losses to potential losses can be assumed to be Substituting and solving for Q gives Webb2 mars 2024 · Method to determine the peak runoff from the property.
