Tr-55 Time Of Concentration Calculator

TR-55 Time of Concentration Calculator

Calculating the Time of Concentration (TOC) is an essential step in hydrology and stormwater management. The TR-55 Time of Concentration Calculator helps engineers and planners determine how quickly rainwater will flow across a watershed to a specific point, such as a drainage ditch or culvert. This calculation is crucial for designing effective stormwater management systems to prevent flooding and erosion.

What is Time of Concentration?

Time of Concentration is the time taken for rainwater to travel from the most remote point in a watershed to a specific location of interest. It is a critical parameter in hydrology as it helps determine the peak flow rate and volume of stormwater runoff. The TR-55 Time of Concentration Calculator uses various methods, such as the Kirpich equation or the Rational Method, to estimate the TOC based on watershed characteristics.
