I need to divide my watershed by isochrones of equal travel time to the output, dividing my watershed to inter-isochronal areas in order to use the time-area method to calculate runoff time series, in other words I want to divide my catchment like this:Example of an isochrone divided watershed and the resulting runoff time series

Note that, I already have my concentration time values calculated, I just want to divide my watershed based on concentration time now.
