The Muskingum-Cunge method in which the parameters K and X are allowed to vary in time and space is investigated. A three-point approach and an iterative four-point approach to the calculation of the variable parameters are shown to be sufficiently accurate in the simulation of flood flows. A two-point approach is shown to be inaccurate in the calculation of peak discharge and travel time. Furthermore, the two-point method results in a significant loss of mass.
