Who is the main developer for ArcHydro? Ive found the HEC-GeoHSM watershed processing algorithms are the exact same as arcHydro. As Im sure this is no coincidence, which came first? Does ACoE control/oversee development of both?

Thanks for your help. Im working an uncertainty analysis report that is investigating the differences between terrain processing methods/options in ArcGIS. Any extra information you may have (eg lists of hydro extensions, documentation of background algorithms, etc would be extremely helpful)
