Kirpich Adjustment Factor

Go Kirpich Adjustment Factor = sqrt(Maximum Length of Travel of Water^3/Difference in Elevation)

Maximum Length of Travel of Water

Go Maximum Length of Travel of Water = (Time of Concentration/(0.01947*Slope of Catchment^(-0.385)))^(1/0.77)

Slope of Catchment about given Time of Concentration

Go Slope of Catchment = (Time of Concentration/(0.01947*Maximum Length of Travel of Water^0.77))^(-1/0.385)

Kirpich equation for Time of Concentration

Go Time of Concentration = 0.01947*(Maximum Length of Travel of Water^0.77)*Slope of Catchment^(-0.385)

Kirpich Equation

Go Time of Concentration = 0.01947*Maximum Length of Travel of Water^(0.77)*Slope of Catchment^(-0.385)

Time of Concentration from Kirpich Adjustment Factor

Go Time of Concentration = 0.01947*Kirpich Adjustment Factor^0.77

Time of Concentration from Kirpich Adjustment Factor Formula

Time of Concentration = 0.01947*Kirpich Adjustment Factor^0.77
t_c = 0.01947*K₁^0.77

What is Time of Concentration?

Time of concentration is a concept used in hydrology to measure the response of a watershed to a rain event. It is defined as the time needed for water to flow from the most remote point in a watershed to the watershed outlet. It is a function of the topography, geology, and land use within the watershed.

What is the Catchment Area of a river?

A water catchment (commonly referred to as a “watershed”) is an area of land where all water flows to a single stream, river, lake or even ocean. Natural boundaries of water catchments can be very small for a single creek or stream or quite large.
