Watershed Bounded Network Model WBNM 2007

The Watershed Bounded Network Model WBNM for flood estimation on natural and urban catchment was originally developed by Michael Boyd, David Pilgrim and Ian Cordery from 1975-1979. Subsequent versions were prepared by Michael Boyd, Bryson Bates, David Pilgrim and Ian Cordery in 1987, and Michael Boyd, Ted Rigby and Rudy Van Drie from 1994-2005.
