A practical methodology of design of off-line reservoirs for reducing maximum water levels in urban channels
Coronado-Hernández, Oscar E.; Coronado-Hernandez, Jairo R.; Gustavo, Gatica (Corporación Universidad de la Costa, 2020)Flooding can often occur in many places due to the increasing trend of rainfall events (climate change), the urbanization process of a catchment area, or by an undersized urban channel. Reservoirs are used for limiting ... -
Assessment of steady and unsteady friction models in the draining processes of hydraulic installations
Coronado-Hernández, Oscar E.; Derpich, Ivan; Fuertes-Miquel, Vicente S.; Coronado-Hernandez, Jairo R.; Gustavo, Gatica (WATER, 2021-07)The study of draining processes without admitting air has been conducted using only steady friction formulations in the implementation of governing equations. However, this hydraulic event involves transitions from laminar ... -
Isohyetal maps of daily maximum rainfall for different return periods for the Colombian Caribbean Region
González-Álvarez, Álvaro; Viloria-Marimon, Orlando M.; Coronado-Hernández, Oscar E.; Vélez-Pereira, Andrés M.; Tesfagiorgis, Kibrewossen; Coronado-Hernandez, Jairo R. (Corporación Universidad de la Costa, 2019-02-20)In Colombia, daily maximum multiannual series are one of the main inputs for design streamflow calculation, which requires performing a rainfall frequency analysis that involves several prior steps: (a) requesting the ... -
Selection of hydrological probability distributions for extreme rainfall events in the regions of Colombia
Coronado-Hernández, Oscar E.; Merlano-Sabalza, Ernesto; Díaz-Vergara, Zaid; Coronado-Hernandez, Jairo R. (Corporación Universidad de la Costa, 2020-05-10)Frequency analysis of extreme events is used to estimate the maximum rainfall associated with different return periods and is used in planning hydraulic structures. When carrying out this type of analysis in engineering ... -
Simplified mathematical model for computing draining operations in pipelines of undulating profiles with vacuum air valves
Coronado-Hernández, Oscar E.; Fuertes-Miquel, Vicente S.; Quiñones-Bolaños, Edgar; Gustavo, Gatica; Coronado-Hernandez, Jairo R. (Corporación Universidad de la Costa, 2020-09-11)The draining operation involves the presence of entrapped air pockets, which are expanded during the phenomenon occurrence generating drops of sub-atmospheric pressure pulses. Vacuum air valves should inject enough air to ...
