Los aliviaderos tipo laberinto. Un nuevo enfoque para su cálculo hidráulico

Abstract

At present, The Poiythencic University of Madr id, the CEDEX and JESÚS GRANELL ingenieros Consultores Company are carrying out an investigation project on labyrinth spillways. As a part of this project, it is proposed a new method for the hydraulic calculation of this type of spillways, which is based on the main facts occurred: the obliquity of the diagonal faces of the weir referred to the direction of the flow upstream in the approximation, and the nappe interference. The method is going to be improved a nd validated by physical a nd numerical modelling as a pa rt of the investigation project. However, the comparison of its preliminary results with other methods, and also with some physical models available provides encouraging results.
