The development of a general purpose river basin distributed simulation model is described. The problems of network decomposition and lumped-parameter element recognition are discussed, and a scheme suitable for any specific tree-like network proposed. Two methods of flood routing within the individual elements have been implemented in the currently operational model, these being the simple non-linear kinematic wave model and a complex linear solution to the full equation of motion. The properties and behavior of these routing models under various conditions are examined, and recommendations regarding their suitability in various flow regimes set forth. Results obtained using these routing techniques are compared to both experimental and field data and to those obtained using a numerical solution of the full non-linear equations. A problem-oriented language suitable for river basin simulation studies has been developed and implemented on a time sharing system. (Author)
