Experimental and Numerical Analysis of Egg-Shaped Sewer Pipes Flow Performance
(Multidisciplinary Digital Publishing Institute, 2016)
A Computational Fluid Dynamics (CFD) model was developed to analyze the open-channel flow in a new set of egg-shaped pipes for small combined sewer systems. The egg-shaped cross-section was selected after studying several ...
Nonintrusive Method to Compute Water Discharge in Pipes with a Low Depth-to-Diameter Ratio Using Ultrasonic Doppler Velocimetry
(ASCE, 2015)
[Abstract] A nonintrusive method to calculate water depth and discharge in partially full pipes using data from a single ultrasonic Doppler velocimeter (UDV) profiler is presented. The position of the free surface is ...
Development and Calibration of a New Dripper-Based Rainfall Simulator for Large-Scale Sediment Wash-off Studies
(MDPI, 2020)
[Abstract] Rainfall simulators are useful tools for controlling the main variables that govern natural rainfall. In this study, a new drop-forming rainfall simulator, which consists of pressure-compensating dripper grids ...
Assessing Different Imaging Velocimetry Techniques to Measure Shallow Runoff Velocities During Rain Events Using an Urban Drainage Physical Model
(Copernicus GmbH, 2021)
[Abstract] Although surface velocities are key in the calibration of physically based urban drainage models, the shallow water depths developed during non-extreme precipitation and the potential risks during flood events ...
Global and local sensitivity analysis to improve the understanding of physically-based urban wash-off models from high-resolution laboratory experiments
(Elsevier, 2019)
[Abstract:] Physically-based urban wash-off models are a promising means of studying the transport of finer suspended solids and their associated pollutants during rain events, considering spatial and temporal heterogeneities. ...
New insights to study the accumulation and erosion processes of fine-grained organic sediments in combined sewer systems from a laboratory scale model
(Elsevier, 2020)
[Abstract:] The deposition and resuspension of sediments are issues of considerable concern in combined sewer systems management. Sediments can produce the loss of hydraulic capacity and odour generation in sewers, and are ...
Using a 2D shallow water model to assess Large-Scale Particle Image Velocimetry (LSPIV) and Structure from Motion (SfM) techniques in a street-scale urban drainage physical model
(Elsevier, 2019)
[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 ...
Large-scale physical facility and experimental dataset for the validation of urban drainage models
(Wiley, 2024)
[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 ...
Hydraulic, Wash-off and Sediment Transport Experiments in a Full-Scale Urban Drainage Physical Model
(Nature, 2020)
[Abstract] This paper presents a dataset obtained from hydraulic and sediment transport experiments performed in a full-scale urban drainage physical model of 36 m2. The study seeks to accurately measure sediment mobilization ...
Análisis integral del lavado y arrastre de sólidos en suspensión en cuencas urbanas utilizando un simulador de lluvia a escala real
(Universitat Politècnica de València, 2022)
[Resumen:] Ante la falta de datos experimentales precisos para el desarrollo y validación de modelos de lavado y transporte de sedimentos
en la superficie de cuencas urbanas, en este estudio se presenta una serie de ensayos ...
