Evaluación y diagnóstico del sistema de riego Canal Alto San Pedro de Vilcabamba - Parte 1

Abstract

Abstract:In this investigation, the diagnosis and evaluation of the irrigation system of San Pedro de Vilcabamba in the section between the abscissa 0+000 km and 5+000 km. The components of the irrigation system were inventoried and information was collected in the field of the sections and the flow of water in the canal. It was determined that the flow regime in the section of the study channel is subcritical, except for the sections of the channel in which abscissas 0+239 km, 0+300 km, 1+400 km and 4+000 km, where the flow is supercritical due to to a sudden change in slope. The intake and sand trap are saturated with sediments. The hydraulic efficiency of channel conduction from the abscissa 0+000 km up to 5+000 km it has decreased by 29.5%, which represents 63.21 L/s of water. This loss of water flow is due to the lack of construction of side gates. the flow of water in the section 0+239 km to 0+300 km it has an erosive velocity of 2.8 m/s, and in the section 4+300 km to 4+400 km a sedimentation velocity of 0.41 m/s.
