[Objective] Aiming to solve the problems that the water measuring and monitoring of chan- nel transmission and distribution are relatively lagging behind, and various calculation programs or soft- wares are of certain limitations at present, an integrative programming appropriate for the calculation of hy- draulic parameters of channels with different section patterns is developed. [Method] Based on Visual Basic and design ideas of modularization and combined with multi-sections, multi-parameters, real-time, analytici- ty,summary, and storage, an integrative procedure on calculation and analysis of hydraulic parameters, which can be run in Windows 7, Vista and later versions, is devised for irrigation water characteristics. The procedure was used in an irrigation district, and the calculated flow capacity was compared with the results measured by a hydrometic propeller. [Result] An integrative programming on hydraulic parameters calcula- tion of channels with different section patterns was successfully developed and the largest relative error was 1.35% comparing to measurement. [Conclusion] This procedure can calculate the real-time capacity and velocity and summarize and analyze the water quantity in an irrigation district.
