| dc.description.abstract | Scale-model tests are usually required to evaluate the hydraulic and structural behavior of proposed rubble-mound breakwater designs. In order to speed up and ease the armor layer damage assessment, we developed a technique based on stereo photogrammetry. A key feature of this technique is its ability to compensate for the refraction in the air-water interface, thus producing a survey of the envelope of the armor layer without the need to empty the wave flume or wave basin where the scale model tests are carried out. This article describes this technique and the tests made to establish confidence in it and in the damage evaluation on a breakwater scale model. Results led to an error estimation of only fractions of a centimeter. Los ensayos con modelos físicos a escala reducida son muchas veces necesarios, a fin de evaluar el comportamiento hidráulico y estructural del proyecto propuesto. Con el fin de acelerar y facilitar la evaluación de los daños a la envoltura del manto de rompeolas de la escollera, desarrollamos una técnica basada en la estéreo fotogrametría. La característica principal de esta técnica es su capacidad para compensar la refracción en la superficie entre aire-agua, produciendo así un levantamiento del manto resistente, sin necesidad de vaciar el canal o el tanque de oleaje donde los ensayos con modelos a escala se llevan a cabo. En este artículo se describe esta técnica y las pruebas realizadas para establecer una confianza en la evaluación de los daños con un modelo del rompeolas a escala reducida. El error resultó ser en fracciones de centímetro. | pt_PT |
