WebThe parameter CN is a transformation of S, and it is used to make interpolating, averaging, and weighting operations more linear (4). With the following chart, the amount of runoff can be found if the rainfall amount (in inches) and curve number is known. There are two advantages of ... WebThe spatial inundated depths predicted by the MORF model were close to those of the coupled model, with differences typically less than 0.1 m and an average correlation coefficient reaching 0.951. The MORF model, however, achieved a computational speed of 200 times faster than the coupled model. tebco electric trikes https://marinchak.com

WebThe coefficient of runoff also varies for different storms on the same catchment, and thus, using an average value for C, gives only a rough estimate of Qp in small uniform urban areas. On top of this the rational formula has been used for many years as a basis for engineering design for small land drainage schemes and storm-water channels (ERA, 2013).
