Abstract: The algorithms of definition of parameters of leaks in pipelines obtained by the equations of hydrodynamic processes, occuring during leaks, are considered. These algorithms are obtained for the section of a continuous linear pipeline without additional taps laid between two pump stations. The pipeline is supposed to transport homogeneous fluid. The possibility to increase the speed of the presented algorithms is considered. The results of the research of the offered algorithms of defining the parameters of the leak are presented
