2024年2月29日 · This steps assumes that the user already has a total rainfall hyetograph in MS Excel. This total rainfall hyetograph for a single event is then used as input to separate rainfall abstractions or losses by using the SCS CN method. There are two outputs from this step, including the rainfall abstractions and the excess rainfall hyetograph.

2013年11月1日 · 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 of...

2014年2月23日 · 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. View full-text Data

2020年5月6日 · This excel sheet provides the dimensionless values for the mass curve based on the SCS-Type II hyetograph for the use in hydrological modeling. The sheet shows an example.

2024年1月10日 · SCS-CN方法是一种以经验数据为支撑的暴雨水文抽象概念模型,该模型基于一个数值参数CN来估计直接径流量，与Green-Ampt、Philip和Horton入渗曲线等相比，所需资料容易获取且计算过程简单。

This Excel spreadsheet implements the method described in “Computing Flood Discharges For Small Ungaged Watersheds.” The spreadsheet is set up with worksheets that perform calculations for specific aspects

2003年9月30日 · Here are all of the SCS rainfall distributions in a text file that can be imported into XP-SWMM directly or opened and parsed in Excel, etc. Most distributions are 6 minutes. Does anyone have a good source for the ordinates of the SCS Type II 24-hr hyetograph on 10- or 15-minute intervals?

The United States Soil Conservation Service (SCS) has identified four soil group classifications (A, B, C, or D) that can be used to help in determining values for drainage area runoff coefficients. Determination of which SCS soil group fits a particular soil may be on the basis of …

TORMENTA_SCS.xlsx - Free download as Excel Spreadsheet (.xls / .xlsx), PDF File (.pdf), Text File (.txt) or read online for free. The document contains rainfall distribution data for different durations (6 hours, 12 hours, etc.) that have been transformed from 24-hour rainfall distributions.

The Hypothetical Storm precipitation method provides the ability to assign different storm durations and temporal patterns. Several default temporal patterns are available for the user to select...
