How to fill out time of concentration tc

01
To fill out the time of concentration (tc), follow these steps:
02
Determine the watershed area: Measure or calculate the total area of the watershed in square units.
03
Identify the longest flow path: Determine the longest distance that water would travel within the watershed from its farthest point to the outlet.
04
Calculate the average slope: Measure the change in elevation over the longest flow path and divide it by the length of the flow path.
05
Determine the surface roughness coefficient (n): This represents the roughness of the ground surface within the watershed and can be estimated based on the type of land use and vegetation.
06
Select the rainfall duration: Choose the appropriate duration of rainfall for the region or specific project.
07
Choose the appropriate rainfall intensity: Determine the intensity of rainfall based on the design requirements or regional rainfall data.
08
Use the Rational Method equation: Apply the Rational Method equation, Q = CiA, where Q is the peak discharge, C is the runoff coefficient, i is the rainfall intensity, and A is the watershed area.
09
Calculate tc: Rearrange the Rational Method equation to solve for tc by dividing the length of the longest flow path by the average velocity, which is calculated as Q / A.
10
Verify and adjust the results: Analyze the calculated time of concentration and make adjustments if necessary based on local factors or additional data.
11
Document the results: Record the calculated time of concentration, including all the parameters used in the calculations, for reference and future use.
