Automatic calculation of Hydraulic length

Question

Hello Everyone, 
 
 Can anyone tell me whether SewerGEMS CONNECT edition can calculate hydraulic length and slope of a catchment automatically? if so how? I used the feature of automatic catchment delineation in the software but it did not give Hydraulic length automatically.

Hello Jainesh, 
 Currently you can delineate the catchments and assign catch basins based on downstream trace. However, automatic calculation of hydraulic length to compute time of concentration is not currently available. You have to know the velocity and hydraulic length before you calculate the time of concentration which can be used as in input to determine the runoff from the delineated catchment. 
 For more information on Catchment Delineation please refer the below article;

 Hope this helps.

Hello Jainesh, 
 The ability to automatically calculate catchment hydraulic length and slope based on a terrain model will be considered for a future release.
