Aliviaderos escalonados sin cajeros laterales. Projecto ALIVESCA

En el presente trabajo se muestran los primeros resultados del proyecto de investigación aplicada colaborativa entre el Instituto de Investigación FLUMEN de la Universidad Politécnica de Catalunya (UPC), el Centro de Estudios Hidrográficos del CEDEX y DRAGADOS, con el objetivo de establecer los criterios hidráulicos para el diseño de rápidas escalonadas sin los tradicionales cajeros laterales que confinan el flujo (proyecto ALIVESCA)

Two-dimensional modelling of discharge distribution in vegetated compound channel (Besòs river)

Flow distribution in Besòs river is studied by means of a two dimensional numerical model and a scale model. Besòs river presents a compound channel floodway with a central sinusoidal main channel and floodplains at each side of it. Floodplains are used for wastewater treatment and for that reason covered with flexible 2m high vegetation. It is shown that good agreement of numerical model and physical model is achieved with a high resolution numerical model based on the conservative form of Saint Venant equations and finite volumes, provided variations of roughness with unit discharge is taken into account, with no need of turbulence models. Good results are achieved in predicting lateral discharge distribution and flow exchange from main channel and floodplains with the two dimensional approach, something that cannot be done with one dimensional models as exemplified with a one dimensional simulation of the same case.Postprint (author’s final draft

Caruachi dam. Study of the hydraulic behaviour of the diversion conduits

Se presenta el estudio desarrollado en el Laboratorio de Modelos Reducidos del Dpto. de Ing. Hidráulica, Marítima y Ambiental de la UPC, para el análisis del comportamiento hidráulico de las compuertas a utilizar en la operación de cierre de la presa de Caruachi en el río Caroní (Venezuela). Se han analizado la capacidad de desagüe, la aireación de los conductos de desvío, las presiones en los mismos durante la operación, así como las vibraciones y fuerza vertical descendente (down-pull) sobre las compuertas.The present article describes the study carried out at the Reduced Model Laboratory (Hydraulic, Maritime and Environmental Engineering Department, UPC) into the hydraulic behaviour of the gates employed in the closing operation of the Caruachi dam on the River Caroní (Venezuela). An analysis is made of the discharge and aeration capacity of the diversión conduits, the operation pressures in the same and the vibration and down-pull on the gates.Postprint (published version
