This paper addresses the application of C languagees in developing hydraulic engineering software and depicts the implementation and the rigorous verification of a gererally applicable finite difference numerical model, tailored for use on the IBM PC/XT or PC/AT personal computers, for simulation of unsteady open channel flow. The program is written in the C language, compiling and executing under the integrated program environment TURBO C version 2.0. The various advantages and limitations of employing the TERBO C environment in developing hydraulic engineering software are also presented thoroughly. In the development of the mathematical model, apart from the simplified channel tests where analytical results are available. The program's successful application provides confidence for its capablity as a predictive tool in situations involving complex bathymetry and/or nonlinear bottom frictional effects.
