Rainfall and Watershed Analysis:
- Directly enter the peak flow rate if you already know it
- Choose between the widely accepted Rational Method or SCS Graphical Peak Method to automatically determine the flow at your crossing
- Input an unlimited number of watershed sub-areas, along with their corresponding runoff coefficients
- Let CulvertMaster automatically determine the total area and weighted runoff coefficient
Rational Hydrology: Enter equations, tables, or Hydro-35 data to create your Intensity-Duration-Frequency (IDF) curves for Rational Method storm events. You can reuse your IDF rainfall data for projects that are in the same region.
SCS Hydrology: Choose an SCS type I, IA, II, or III storm for calculating the peak flow rate based on the SCS Graphical Peak Method.
