As well as HEC-2 and similar models serve the profession, problems exist with their application. In general, inflexibility of use and inaccuracies around transitions between subcritical and supercritical flow are the key difficulties. Models currently available do not have the capability to make hydraulic decisions regarding location of transitions, nor the flexibility to easily allow the user to vary cross sectional spacing to check for computational error. The development of such a model is the subject of this paper. A procedure to determine the water surface profile was developed based upon a paper published by A. Molinas and C.T. Yang. Profile computation and application results are discussed.
