The tables provide estimates of the curve number (CN) as a function of hydrologic soil group (HSG), cover type, treatment, hydrologic condition, antecedent runoff condition (ARC), and...
29 Φεβ 2024 · The objective of this step is to learn how to compute excess rainfall hyetograph from a total rainfall hyetograph using the Soil Conservation Service's (SCS) Curve Number (CN) method. This steps assumes that the user already has a total rainfall hyetograph in MS Excel.
8 Μαΐ 2015 · This is an Excel sheet that tabulates the SCS-CN curve number to simplify getting the values from the graph under normal, dry and wet conditions.
1 Νοε 2013 · This spreadsheet is designed to calculate excess rainfall from total rainfall of a storm. The sheet need to provide CN curve number and storm distribution as cumulative rainfall over the time...

14 Ιαν 2021 · This method was originally developed by the U.S. Department of Agriculture, Soil Conservation Service (now known as Natural Resources Conservation Service—NRCS) to predict direct runoff volumes for given rainfall events and mainly for the evaluation of storm runoff in small agricultural watersheds.
The SCS Runoff Curve Number method is developed by the United States Department of Agriculture (USDA) Soil Conservation Service (SCS) and is a method of estimating rainfall excess from rainfall (Hjelmfelt, 1991). The method is described in detail in National Engineering Handbook (2004).
