abstract = {Numerical models are currently the main tool used to simulate the effects of urban flooding. The validation of these models requires thorough and accurate observed data in order to test their performance. The current study presents a series of laboratory experiments in a large-scale urban drainage physical facility of approximately 100 m2 that includes roofs, streets, inlets, manholes and sewers. The facility is equipped with a rainfall simulator as well as a surface runoff and pipe inflows generators. The experiments were divided in two sets. In Set 1 the surface runoff was generated exclusively by the rainfall input, while in Set 2 the rainfall simulator was used in combination with the runoff generators. In all the tests the water discharge was measured at points on the inlets, roofs, and outfall. The water depth at different locations of the facility was also measured. The experimental tests were replicated numerically using the urban drainage model Iber-SWMM. Experimental results show that, even in a relatively small catchment the peaks in the hydrographs generated at each element of the facility during intermittent rainfalls are significantly attenuated at the catchment outlet. The agreement between the experimental and numerical results show that there are some differences in the hydrographs generated at each element, but that these differences compensate each other and disappear at the outfall. The results generated provide the research community with a thorough and high-resolution dataset obtained under controlled laboratory conditions in a large-scale urban drainage facility, something which has not previously been available.},

abstract = {Physically-based numerical modelling of surface processes in urban drainage, such as pollutant wash-off or the assessment of flood risks, requires appropriate calibration and terrain elevation data to properly simulate the overland flows and thus to achieve useful results. Accordingly, this study aims to obtain an accurate representation of the runoff generated by three different rain intensities, 30, 50 and 80 mm/h, in a full-scale urban drainage physical model of 36 m2. The study focuses firstly on applying the Structure from Motion (SfM) photogrammetric technique to carry out a high-resolution and accurate topographic survey. This topography was implemented in a 2D shallow water model and the results were compared with those obtained using traditional data point measured topography. Negligible differences were found when comparing the two models with measured discharges at the physical model gully pots. However, significant differences were obtained in the velocity distributions, especially in the shallowest flow areas where drainage channels of a few millimeters’ depth appeared in the high resolution topographic survey. Results from the numerical model were compared with overland flow velocities, determined by applying a modified Large Scale Particle Image Velocimetry (LSPIV) methodology using fluorescent particles. With the SfM topography, the 2D model was able to obtain a better representation of the experimental data, since small scale irregularities of the pavement surface could be represented in the model domain. At the same time, LSPIV was presented as a very suitable tool for the accurate measurement of runoff velocities in urban drainage models, avoiding the interference of raindrop features in the recorded images and with overland water depths in the order of few millimeters.},

abstract = {This paper presents an analysis of the stability of breakwater roundheads protected with a Cubipod single-layer armor. This model was then subjected to a battery of 22 physical model tests, and the most significant variables were observed to be wave steepness (spr), the radius divided by the nominal diameter (Rn), and the relationship between the radius and wavelength at the breakwater toe (R/Lrp). It has been demonstrated that there are two behavioral patterns for stability according to the parameter R/Lrp, with large roundheads defined as R/Lrp ≥ 0.15 and small roundheads as R/Lrp < 0.15. The stability reserve (SR [%]) was also calculated and it was demonstrated that this parameter decreased with an increase in steepness. A design criterion was also defined based on the stability reserve (SR [%]) of these kinds of structures. The stability coefficient (Kd) was calculated to account for initial damage, destruction, and the design stage, and it was verified that this parameter depends primarily on wave steepness, to which it is directly proportional. Finally, a comparison with double-layer armors was made confirming that under certain conditions, the single-layer ones have the same stability as the ones with double layer armors, but their behavior is more rigid.},
