Version 6.52HARC is proudly the custodian of the RORBwin and MiRORB software. This software is widely used in Australia and internationally for design flood hydrologic modelling, having a pedigree reaching back to the pioneering work of Prof. Eric Laurenson and Prof. Russell Mein (Monash University) in the late 1970s, and more recently the joint probability developments and other enhancements by Assoc. Prof. Rory Nathan (SKM/Jacobs/Melbourne University). The software is licensed for your use free of charge for now upon registration by You with your email address, which is held in our secure database and will be used to provide information on updates and enhancements to the software. Note: there is no formal support provided for the software, but HARC does, as a goodwill gesture, field queries subject to the restrictions set out in the Licence to the effect we cannot accept any responsibility for that advice (contact RORB@harc.com.au).
