Diseño de un canal para las investigaciones en transporte de sedimentos ubicado en las instalaciones del Laboratorio de Hidráulica de la Escuela Politécnica Nacional.

Abstract

This thesis has the purpose of designing an experimental channel for the study of sediment transport, which will be installed in the Hydraulic Laboratory of the National Polytechnic School. It is based on hydraulic principles that optimize the water conduction generating the least number of losses under the condition of a fixed bed of sediments and gradually varied regime that guarantees the immobility of the bed. The canal has complementary structures for the storage and transport of water through a pumping system and tanks. The hydraulic calculation includes the definition of the geometry, the calculation of lengths of sections upstream and downstream of fixed bed, calculation of structures of control type dump, design of tanks and pipes, design of pumping system, obtaining characteristic curves of flow, energy curves, flow analysis gradually varied through the direct pass method, valve design and waterhammer analysis. The calculation of the gradually varied flow is checked in the software HEC RAS and H Channels, obtaining important similarities and small errors due to the simplifications used by said programs.
