The first analytical solution to the complete nonlinear dynamic wave equations in rivers: It overcomes most restrictions of existing numerical models. No need for a grid, or specialized software; no complex discretization, no special numerical treatment or smoothing of the front wave end; no small perturbation, no numerical instability, no linearization, no replacement of momentum equation by empirical relationships. It represents a physically-based solution of the true nonlinear combined mass and momentum equations. The flood wave is continuous in space and time. Its implementation is extremely simple with any standard mathematics program (e.g., Matlab).
