En este artículo se desarrolla un nuevo modelo pedagógico del aula invertida (FC) y el aprendizaje basado en problemas (PBL) para la enseñanza de la hidrología a estudiantes de ingeniería civil. La investigación fue aplicada de diseño cuasi experimental. Se aplicaron los métodos pedagógicos por un periodo de 10 años en dos universidades públicas, u...
En este artículo se presenta la estimación de la resistencia al flujo en río de montaña por tres métodos. Se aplicaron los criterios estadísticos del error medio cuadrático (RMSE), el coeficiente de determinación (R2) y el diagrama de Taylor en el software R para la calibración de los modelos. El modelo GEP resultó óptimo para estimar el n de Manni...
This paper presents, flow resistance in mountain rivers was estimated by three methods. The Statistical Criterion Mean Squared
Error (RMSE), the Coefficient of Determination (R2), and the Taylor Diagram in R software were applied to calibrate the models. The
GEP model was optimal for estimating Manning’s n with the lowest error of 5%, but it has gr...
The energy efficiency of irrigation systems is an aspect of great importance in all design and management processes; For this reason, an investigation was carried out in the "Tío Pedro" farm located in the municipality of Venezuela, Ciego de Ávila province during the years 2021 and 2022 with the objective of estimating the general energy yield in t...

Soil and water conservation is a priority in the watersheds of arid and semi-arid regions for the proper planning and integrated management of water resources. The objective of this work is prioritizing 91 watersheds in 14 regions of Peru with different geographical, hydrological and geological conditions, through the integration of Geographic Info...
The purpose was to determine the relationship between administrative management and work stress of workers in Metropolitan Lima. While studies in psychology frequently relate work stress to climate and work satisfaction, in this study, we sought to relate administrative management, when it is inadequate, as the generator of the negative work enviro...
In this article, the methodological integration of the flipped classroom (FC) and problem-based learning (PBL) in the teaching of the hydrology course was developed. The research is applied with a quantitative, quasi-experimental approach. It was applied to a sample of 1846 Civil Engineering students over 10 years at universities in Cuba (UC), Peru...
The Colebrook equation has been used to estimate the friction factor (f) in turbulent fluids. In this regard, many equations have been proposed to eliminate the iterative process of the Colebrook equation. The goal of this article was to perform an evaluation, classification, and proposal of the friction factor for better development of hydraulic p...
En el artículo se desarrolló el aprendizaje basado en problemas (PBL) en el curso de Hidrología. Se enfocó en la experiencia de 10 años de dictado de clases con una muestra de 577 estudiantes de la carrera de Ingeniería Civil de Universidades Públicas y Privadas. El PBL fue validado por el Índice de Validez de Contenido (CVI), encuesta analítica y...
Peru is a country recognized for its natural resources, but it is the third most vulnerable country, different research projects have predicted natural. The objective of the research was to hold out the Multivariate Statistical Analysis to 91 watersheds of Peru to get homogeneous water characteristics in different regions. Twenty morphometric param...
Abstract
Soil and water conservation is a priority in the watersheds of arid and
semi-arid regions for the proper planning and integrated management of water resources. The objective of this work is prioritizing 91 watersheds in 14 regions of Peru with different geographical, hydrological and geological conditions, through the integration of Geogra...
This work was carried out at “Ceballos” Citrus Company with the objective of evaluating the phenomenon of hydraulic hysteresis in emitters and self-compensating irrigation tapes. The emitter models Vip Line with a nominal flow of 3.9 L/h and Naan PC with a nominal flow of 4 L/h were evaluated as well as the Aqua Traxx Irrigation Tape. The determina...
In this work, different efficiency criteria were proposed for the evaluation of sprinkler irrigation. The investigation was carried out at six central pivots of the company Cubasoy and La Cuba. The methodology used relates the climatic, hydraulic and energy variables by means of the consumption of the specific energy standardized in the irrigation,...
El presente trabajo ofrece un estudio que se desarrolló en el municipio de Ciro Redondo de la provincia Ciego de Ávila, Cuba, con el objetivo de estimar los impactos del cambio climático sobre las precipitaciones. Se analizó una serie de 40 años, en el periodo comprendido de 1978 hasta el 2017, obtenidos de forma sistemática en el pluviómetro CA 80...
The present work was developed in areas of the Agroindustrial Company of Ceballos, Ciego de Avila, with the objective of carrying out a comparative study of two irrigation tape models, the self-compensating Aqua Traxx and the non-compensating one. The tapes used were the existing models in the company, which were acquired from foreign firms that co...
CurvePivot 2.0 software was developed for the hydraulic design of central pivot irrigation systems for specific operating conditions. The programming language that was used was C # with a simple interface for the user. The program was based on a mathematical model that considers hydrogeological, hydraulic, edaphic, agronomic and economic variables,...
A methodology was developed with the objective of improving the management of micro irrigation systems in the province. The experiments were carried out in areas of University of Ciego de Ávila and “Ceballos” Agroindustrial Company. The work was developed during three years, where the technical - mechanical and hydraulic characteristics of emitters...
The hydraulic design of the central pivot irrigation system was carried out with groundwater extraction for maize cultivation. It was based on the integration of the characteristic curves of the aquifer, the well, the centrifugal pump and the pipes, considering hydrogeological, hydraulic, edaphic and agronomic variables, which generated a nonlinear...
The research was carried out in the Cooperative El Tezón of Ceballos Agroindustrial Company in Ciego de Ávila. Two models of drippers were studied with the objective of evaluating the effect of flow variations on self - compensating emitters in micro irrigation systems in guava (Psidium guajava L.). In mechanical and hydraulic evaluations of emit...
Se exponen los resultados obtenidos de la evaluación de maquinas de pivote central eléctricas producidas por la firma Otech- Irrimec. La evolución del conjunto bomba-motor se realizó conforme a lo establecido por la ABNT (1975). Fueron medidos la potencia del motor, el caudal y la presión a la salida de la bomba. La pérdida de carga en la succión f...
En este trabajo se presentan los resultados obtenidos en los aspectos relacionados con el manejo y la operación los sistemas de Microirrigación. Han sido aplicados los procedimientos desarrollados por Merriam y Keller (2002). Este procedimiento de Merriam y Keller consiste en seleccionar unidades de riego representativas del conjunto de un sistema,...
El presente trabajo se realizó en el laboratorio de química analítica de la Facultad de Ciencias Agropecuarias en la Universidad de Ciego de Ávila con el objetivo de determinar la influencia de la calidad del agua para el riego en las obturaciones de los emisores en Ciego de Ávila.
