  • Hello,

    SewerGEMS includes several standard Tc methods and the Carter method is one of them. It is based on data from Washington, D.C. (USA) and may be best for watersheds with natural channels and partially sewered land uses. 

    Typically you would use a time of concentration method that is accepted by your reviewer, or is a standard for your particular location and type of project. 

    You may want to review engineering reference manuals such as our Stormwater Conveyance Modeling and Design (there is a chapter on Tc), or other journal papers. For example this online paper has some additional information on the Carter method.
