The study investigates four interrelated areas. The first area is concerned with a review and a recalculation of the convergence properties for a simplified form of the St. Venant Equations. The second area consists of investigating a solution procedure which completely linearizes the implicit coefficient matrix about some reference depth and discharge. The validity of this approach is discussed. The third area of study develops a problem-oriented language (POL) input editor suitable for river-basin simulation and implemented on a time sharing system. The fourth area of study is the verification of the unit influence function method of solution for any generalized network of channels. Results from this scheme are applied to field data based on complex multi-looped channel networks. (Author)
