Selection of hydrological probability distributions for extreme rainfall events in the regions of Colombia
(2020-05-14)
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 ...
Hydrological considerations for sizing of a barge discharge pipeline runway
(2021-11-01)
A key element for water supply systems is the design of the water intake components. Mobile floating platforms (barges) are helpful when the hydraulic system displays substantial variations in water levels. This study ...
A preliminary analysis for selecting the best hydrological probability density functions of annual peak flows associated to various return periods in some rivers of Colombia
(2021-11-01)
Analysis of extreme events of annual flow peaks are used for sizing hydraulic structures for specified return period. Cumulative distribution functions are applied to annual flow peak records in order to obtain extreme ...
A practical methodology of design of off-line reservoirs for reducing maximum water levels in urban channels
(2020-08-06)
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 ...
Isohyetal maps of daily maximum rainfall for different return periods for the Colombian Caribbean Region
(MDPI AG, 2019)
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 ...
Analysis of sub-atmospheric pressures during emptying of an Irregular pipeline without an air valve using a 2D CFD model
(2021-09-15)
Studying sub-atmospheric pressure patterns in emptying pipeline systems is crucial because these processes could cause collapses depending on the installation conditions (the underground pipe covering height, type, fill, ...
Concerning Dynamic Effects in Pipe Systems with Two-Phase Flows: Pressure Surges, Cavitation, and Ventilation
(2022-07-31)
The risks associated with unsteady two-phase flows in pressurized pipe systems must be considered both in system design and operation. To this end, this paper summarizes experimental tests and numerical analyses that ...
Transient phenomena generated in emptying operations in large-scale hydraulic pipelines
(2020-08-18)
Air pockets generated during emptying operations in pressurized hydraulic systems cause significant pressure drops inside pipes. To avoid these sudden pressure changes, one of the most widely used methods involves the ...
Maniobras de llenado y vaciado en grandes conducciones. Aplicación a una tubería de fundición DN400 en Massamagrell (Valencia, España)
(2020-01-31)
Air pockets inside hydraulic installations during filling and emptying processes can generate pressure surges and negative pressure, respectively. Serious damages can be occurred in pipelines. In order to analyse hydraulic ...
Assessment of Steady and Unsteady Friction Models in the Draining Processes of Hydraulic Installations
(2021-07-08)
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 ...
