Isochrone maps - are they widely available?

  1. Dec 19, 2011 #1
    I need isochrone maps for a water contamination analysis. Does anyone know if these are widely available? A quick google search hasn't given me much, just information on what they are.

    I could use the rational method to calculate the runoff instead, but I would rather the time-area method, for which I need the isochrone maps.

    Ideally I would like to calculate the amount of runoff going into the river at different points along it.

    Would these be for the Sahara Desert?

    I am, of course guessing from your time of posting and therefore your probable time zone, in the absence of better information.
