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 ...

Purpose: This paper presents a multi-objective programming model for selection of projects for financing new enterprise smes in colombia with objectivity and transparency in every call. approach: the model has four social ...
A Method to Rationalize the Product Portfolio in Retail Stores
(2020-04-29)
Retail store operations face a variety of challenges and complexities. Determining the best assortment is the main problem in the retail store. This re-search presents a practical methodology for the analysis of products ...
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 ...
A Generic Materials and Operations Planning Approach for Inventory Turnover Optimization in the Chemical Industry
(2020-05-22)
Chemical industries usually involve continuous and large-scale production processes that require demanding inventory control systems. This paper aims to show the results of the implementation of a mixed-integer programming ...
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 ...
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 ...
Simplified mathematical model for computing draining operations in pipelines of undulating profiles with vacuum air valves
(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 ...
