  • Development and Hydrodynamic Performance of an Oscillating Buoy-Type Wave Energy Converter
    Yeison Berrio, Germán Rivillas-Ospina, Gregorio Posada Vanegas, Rodolfo Silva, Edgar Mendoza, et al.
    Energies, 2025
    The development of wave energy converters (WECs) faces several technical challenges, particularly enhancing the capturing efficiency, improving the conversion of mechanical to electric energy, and reducing energy losses in the transmission of electricity to land-based facilities. The present study is an assessment of the interaction between an oscillating buoy-type wave energy converter (WEC) and waves using experimental and numerical methods. A small-scale model was tested in a wave tank to evaluate its energy capturing efficiency, taking wave heights and periods as independent variables. The recorded data were used to validate OpenFOAM (version 9.0) simulations, which provided insights into system response characteristics. The findings highlight the critical role of resonance in optimizing energy capture, with maximum efficiency observed for medium wave periods, and with specific buoy configurations. The study also identified an inverse relationship between the capture width ratio and wave height, suggesting the need for customized buoy designs, tailored to specific sea states. The integrated approach used in this research provides a comprehensive understanding of WEC behaviour and offers valuable insights for advancing wave energy technologies and improving their sustainability and efficiency in diverse marine environments.
  • Incorporating Uncertainty and Failure Probability in the Design of Urban Stormwater Channels for Resilient Cities
    Stefany Anaya-Pallares, Humberto Avila-Rangel, Oscar E. Coronado-Hernández, Augusto H. Sisa-Camargo, Modesto Pérez-Sánchez
    Water Switzerland, 2025
    The conventional practice in the design of storm drainage systems is based on statistically stationary load and resistance conditions that remain invariant over time. However, uncertainties in the variables affect the design accuracy and the satisfactory performance of these hydrosystems during their operation and service. To overcome this limitation, a design methodology for a storm drainage channel was proposed using a probabilistic framework that incorporates uncertainty analysis of random variables and estimates the system’s probability of failure in terms of design depth and maximum allowable velocity. This methodology employs the Monte Carlo simulation technique and offers an alternative design and analysis approach to strengthen the conventional sizing method for drainage channels in urban watersheds. Based on uncertainty criteria associated with hydraulic design, operation, and prospective changes in the watershed and the channel, appropriate dimensions were estimated regarding design depth and freeboard. The results of this study demonstrate that the annual probability of failure of a channel, when considering uncertainty, is significantly higher than the yearly exceedance probability associated with the hydrological design return period event. Therefore, the proposed methodology is appropriate for estimating the system’s capacity and potential failure risk. This methodology may also be applied to sizing other stormwater drainage structures.
  • Predicting the Tensile Properties of Carbon FRCM Using a LASSO Model
    María Rodríguez-Marcos, Paula Villanueva-Llaurado, Jaime Fernández-Gómez, Joaquín Abellán-García, Augusto Sisa-Camargo
    Fibers, 2024
    The use of Fibre Reinforced Cementitious Matrix (FRCM) for structural retrofitting requires prior assessment of the composite’s mechanical properties, particularly its tensile stress–strain response. This paper presents a LASSO regression model applied to 107 uniaxial tensile tests on Carbon FRCM in order to investigate the impact of both the material and testing parameters on FRCM performance. A highly effective LASSO regression model was trained using k-fold validation, resulting in concise and comprehensible models. Within the testing parameters, both the gripping system and load–speed ratio significantly affected the performance. A substantial impact on ultimate values was found for the load–speed ratio. From the material-related parameters, the most influential was the textile coating in terms of strength and the existence of bilinear or trilinear behaviour. It was also concluded that the combination of textile and matrix properties influenced the stress–strain response at all stages, with high-performance mortars resulting in better textile-to-matrix interaction.
  • Alternatives for recovering the ecosystem services and resilience of the Salamanca Island Natural Park, Colombia
    German Rivillas-Ospina, Mauro Antonio Maza-Chamorro, Sebastián Restrepo, Debora Lithgow, Rodolfo Silva, et al.
    Water Switzerland, 2020
    From a comprehensive diagnosis of the associated basins, islands, and wetlands of the coastal lagoon system of Ciénaga Grande de Santa Marta, Colombia, this work describes feasible options for the recovery of its ecosystem’s health and ecological resilience. Firstly, the state of the coastal lagoon was assessed, finding that hydrology, wave climate, and the morphological changes of the coastline explain recent changes in the coastal wetlands. Key variables were used to describe the level of conservation or degradation of the coastal lagoon system and to identify measures to improve its ecological functions. Finally, to mimic some of these functions and improve connectivity of the ecosystems, green infrastructure alternatives were proposed for the short and medium term to recover the services of these ecosystems and restore their resilience.

  • STORMWATER INFRASTRUCTURE FOR FLASH FLOOD MANAGEMENT AND SUDS MASTER PLAN NEEDS FOR THE CITY OF BARRANQUILLA
    HUMBERTO AVILA, AUGUSTO SISA, LEANDRO AVILA
    Proceedings of the IAHR World Congress, 2019
    The city of Barranquilla has had one of the biggest challenges of stormwater management in Latin America. The city lacks from conventional stormwater conveying and the main streets become dangerous urban streams with flash floods that put the population at risk every year. Urban streets suddenly convey flow rates of up to 100 m 3 /s with velocities greater than 9 m/s. However, in the last 5 years, the local government has implemented an unprecedented project of channeling about 20 km of main streets with flash floods issues, investing more than US$ 200 million dollars. The city has had an important urban transformation in several areas and has significantly reduced the risk associated with flash floods in main streets. However, this effort was mainly focused on channeling and no watershed management measured has been taken into account so far. Based on hydrological risk analysis and the identification of runoff water quality issues, a stormwater master plan based on Sustainable Urban Drainage Systems (SUDS) becomes a need and a great opportunity for the city. This master plan will allow mitigating flash floods in areas which still lack from stormwater conveying systems and improving the water quantity and quality indicator for new urban areas. This document shows the historical evolution of stormwater management in Barranquilla and the arguments for implementing SUDS as a part of a master plan to solve and prevent urban floods and improve runoff water quality in the future.

  • Dispersed storage as stormwater runoff control in consolidated urban watersheds with flash flood risk
    Humberto Avila, Leandro Avila, Augusto Sisa
    Journal of Water Resources Planning and Management, 2016
    This article presents the results of analyzing the use of dispersed storage tanks as a low impact development (LID) alternative to mitigate the flash flood risk in consolidated urban watersheds in Barranquilla, Colombia. Fieldwork, rainfall and flow rate monitoring, and numerical modeling were conducted to evaluate different scenarios combining storage tank capacity, two types of storage operations, and different locations by land use and watershed sectoring. These results showed that it is possible to reduce significantly the peak flow with small-capacity tanks distributed in the urban watershed with hydraulic structures that divide the discharge during the peak-flow time interval. By storing 3–17% of the runoff volume, equivalent to a dispersed storage capacity from 4 to 19 mm rainfall, it is possible to reduce the peak flow from 25 to 75%. These results demonstrate the advantages of using low impact development for stormwater management in consolidated cities with limited space, if regulatory p...
  • Hydrological analysis of the water flow through the Excellence Development Zone (Magdalena, Colombia)

    Wit Transactions on Ecology and the Environment, 2007
    The Excellence Development Zone is located on the eastern shore of the Magdalena River, and belonged to the Natural Reserve of the Salamanca Park in the Santa Marta’s Big Marsh Ramsar site. This zone was split in order to allow the socioeconomic development in Palermo (Sitionuevo, Magdalena). Due to the lack of certain knowledge of the flow behaviour in this zone, and to make an appropriate distribution of the land for different kind of activities, a hydrological study of the EDZ was carried out. According to the data collected, it was determined that the water enters the zone mainly through the Clarin Nuevo drain, across the south portion of the EDZ near to Palermo, meeting the water coming from the sea and the Santa Marta’s Big marsh, and going back underground parallel to the Clarin Viejo drain to the Cantagallo marsh. Following that trends and after making a global environmental analysis, it was recommended to improve the structure of the Clarin Nuevo drain in order to settle most of the particulate material in the water from the Magdalena, avoiding public health and environmental problems.
