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 ...
Modelling Pluvial Flooding in Urban Areas Coupling the Models Iber and SWMM
(MDPI, 2020)
[Abstract] Dual urban drainage models allow users to simulate pluvial urban flooding by analysing the interaction between the sewer network (minor drainage system) and the overland flow (major drainage system). This work ...
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 ...
Revealing the spatio-temporal characteristics of drought in Mozambique and their relationship with large-scale climate variability
(Elsevier, 2021)
[Abstract:] Study region: Mozambique. Study focus: Mozambique does not currently have the necessary tools for systematic monitoring and forecasting of drought at a subnational scale. The purpose of this study was to ...
Two-Dimensional Dam-Break Flood Analysis in Data-Scarce Regions: The Case Study of Chipembe Dam, Mozambique
(MDPI AG, 2017)
[Abstract:] This paper presents the results of a modeling study of the hypothetical dam break of Chipembe dam in Mozambique. The modeling approach is based on the software Iber, a freely available dam break and two-dimensional ...
Joint assimilation of satellite soil moisture and streamflow data for the hydrological application of a two-dimensional shallow water model
(Elsevier, 2023)
[Abstract:] Data assimilation (DA) in physically-based hydrodynamic models is conditioned by the difference in temporal and spatial scales of the observed data and the resolution of the model itself. In order to use remote ...
Development of a global SDG progress index aimed at “leaving no one behind”
(MDPI, 2020)
[Abstract:] The United Nation’s Sustainable Development Goals (SDGs) constitute a set of shared global objectives for the development over the coming years, which both developed and developing countries are working together ...
Comparison of three different numerical implementations to model rainfall-runoff transformation on roofs
(Wiley, 2022)
[Abstract:] Roofs represent a high percentage of the impervious surfaces in urban areas, and hence their implementation in urban drainage models is essential for accurate results to be achieved. Current modelling approaches ...
Analysis of two sources of variability of basin outflow hydrographs computed with the 2D shallow water model Iber: Digital Terrain Model and unstructured mesh size
(Elsevier, 2022)
[Abstract:] Modelling hydrological processes with fully distributed models based on the shallow water equations implies a high computational cost, which often limits the resolution of the computational mesh. Therefore, in ...
