Análisis experimental del transporte de sedimentos en un canal hidrodinámico

Abstract

This thesis presents an experimental study on sediment transport in a laboratory flume, aiming to analyze the evolution of bedforms and determine the initiation of particle movement. Two experiments were conducted: one focused on identifying bedform transitions under increasing flow rates, and another on calculating the shear stress and comparing it with the critical value defined by Shields’ theory. Hydraulic parameters such as mean velocity, shear stress, friction velocity, Reynolds number, and Shields parameter were determined and analyzed. The results were interpreted based on hydraulic theory and national design standards. The findings reveal the transition between ripples, dunes, and antidunes, and confirm the usefulness of the Shields diagram for the design and operation of irrigation canals, stormwater drains, and desilting basins.
