Runoff And Peak Flow Estimation Nrcs Method Pdf Surface Runoff Curve number worksheet: calculates the curve number and precipitation using the scs method. The scs method uses a combination of soil conditions and land uses (ground cover) to assign a runoff factor to an area. these runoff factors, called runoff curve numbers (cn), indicate the runoff potential of an area. The document provides the rational formula and scs curve number method to calculate peak stormwater runoff from a drainage area. it includes the standard assumptions and steps to determine runoff coefficients, time of concentration, rainfall intensities, and peak flows. The curve number method was developed by the usda natural resources conservation service, which was formerly called the soil conservation service or scs — the number is still popularly known as a "scs runoff curve number" in the literature.
Calculation Of Peak Runoff Using Scs Curve Number Method Download Table The document provides the rational formula and scs curve number method to calculate peak stormwater runoff from a drainage area. it includes the standard assumptions and steps to determine runoff coefficients, time of concentration, rainfall intensities, and peak flows. The curve number method was developed by the usda natural resources conservation service, which was formerly called the soil conservation service or scs — the number is still popularly known as a "scs runoff curve number" in the literature. The cn was initially developed as a design tool to estimate runoff from rainfall events on agricultural fields. the sources of the original data are very obscure and difficult to verify. the method is now used as “the” method for computing peak runoff rates and volumes for urban hydrology. We’ll break down the essential equations, explore curve numbers, and walk through sample problems so you can apply this method confidently in your own designs. Learn runoff estimation using scs curve number method & rational method for peak discharge. hydrology, curve numbers, time of concentration. The following procedure can be used to estimate peak discharges for small storm events. it relies on the volume of runoff computed using the small storm hydrology method (pitt, 1994) and utilizes the nrcs, tr 55 graphical peak discharge method (usda, 1986).
