The Modified Rational Method
SpletTR-55 is perhaps the most widely used approach to hydrology in the United States. TR-55 provides a number of techniques that are useful for modeling small watersheds. TR-55 utilizes the SCS runoff equation to predict the peak rate of runoff as well as the total volume. TR-55 also provides a simplified "tabular method" for the generation of ... SpletTR-55 to estimate T c. • Accuracy of peak discharge estimated by this method will be reduced if I a/P ratio used is outside the range given in Exhibits 2-I, 2-II, and 2-III. – The limiting I a/P ratios are to be used. For example: if I a/P in Exhibit 2-II is < 0.1, use 0.1; and if I a/P is > 0.5, use 0.5. ウインナー 焼き時間

The Rational method is appropriate for estimating peak discharges for small drainage areas of up to about 200 acres (80 hectares) with no significant flood storage. The method provides the designer with a peak discharge value, but does not provide a time series of flow nor flow volume. Prikaži več Use of the rational method includes the following assumptions and limitations: 1. The method is applicable if tcfor the drainage area is less than the duration of peak rainfall … Prikaži več The rational formula estimates the peak rate of runoff at a specific location in a watershed as a function of the drainage area, runoff coefficient, and mean rainfall intensity for a duration equal to the time of concentration. The … Prikaži več Urban Watersheds Table 4-10 suggests ranges of C values for urban watersheds for various combinations of land use and soil/surface type. … Prikaži več The rainfall intensity (I) is the average rainfall rate in in./hr. for a specific rainfall duration and a selected frequency. The duration is assumed to be equal to the time of concentration. For drainage areas in Texas, you may … Prikaži več SpletIn the Runoff section of the Property Editor, select Modified Rational Method in the Runoff Method field.
