“…To determine the area of the channel section, three segments were considered and the flow meter was introduced to a depth of 0.2 and 0.8 % of the hydraulic load in each segment. Therefore, the hydraulic flow rate (Q) was obtained through the continuity equation (CNA-IMTA, 2000;Sánchez, Velásquez, Esquivel, Bueno, & Pedroza, 2015):…”

Estimación de la eficiencia de riego superficial parcelario en un módulo del distrito 017 Región Lagunera

et al. 2018

La agricultura en México utiliza 80 % del volumen de agua disponible para irrigar 6.5 millones de hectáreas con eficiencias globales menores al 40 %. Por lo tanto, realizar acciones que incrementen la eficiencia en el uso del agua de riego es importante. Por dicha razón, el objetivo de este trabajo fue determinar las eficiencias en el manejo del agua de riego superficial en un módulo del distrito de riego 017 Región Lagunera, con la finalidad de identificar áreas de oportunidad que permitan incrementar la eficacia global del módulo. Para esto, las eficiencias de conducción de la red de distribución se evaluaron por medio del método área velocidad. También, las láminas de riego aplicadas en cada evento de riego se determinaron mediante aforos en la bocatoma de la parcela. Para determinar la eficiencia parcelaria fue necesario estimar los requerimientos hídricos de los cultivos mediante el software IRRINET. La efectividad de conducción promedio fue de 80.4 %; las mayores pérdidas por conducción se presentaron en los canales interparcelarios no revestidos (20.1 L∙s-1∙10 0 m-1). Respecto a la eficiencia superficial parcelaria, el promedio fue de 59.4 %, lo cual indica que los usuarios están aplicando más agua de lo requerido por los cultivos.

“…Para determinar el área de la sección del canal se consideraron tres dovelas y el molinete se introdujo a una profundidad de 0.2 y 0.8 % del tirante hidráulico en cada dovela. Por lo tanto, el gasto hidráulico (Q) se obtuvo mediante la ecuación de continuidad (CNA-IMTA, 2000; Sánchez, Velásquez, Esquivel, Bueno, & Pedroza, 2015):…”

“…Where: Permeability or hydraulic conductivity (Papierowska et al, 2018) was calculated using a permeameter (with internal diameter D = 6.4 cm, height L = 15.3 cm) (Cotecno Falling Head Permeameter, Santiago, Chile), in which h values are measured, obtained for various times elapsed from the beginning of the test. Then, the soil permeability coefficient, k, is calculated using Darcy's Law, according to Equation (2) and Equation ( 3), (Wang et al, 2020):…”

“…Also, the management of a basin must be oriented to the rational use of its resources, i.e., to order and spatially distribute their use ( Sánchez-Cohen et al ., 2015 ). Management is important, as a basin has environmental, social, economic, and cultural implications in the distribution of water resources ( Sánchez-Cohen et al ., 2015 ).…”

Determination of field capacity in the Chibunga and Guano rivers micro-basins

et al. 2021

Background: The micro-basins of the Chibunga and Guano rivers are located within the sub-basin of the Chambo River, which starts at the thaw of the Chimborazo, crosses the cities of Guano and Riobamba, and ends in the Chambo River. These rivers are considered fluvial hydrological forces and geological limits of the aquifer, located in this sub-basin. For this reason, our investigation addressed the field capacity in the micro-basins of Chibunga and Guano rivers, to determine the maximum retention potential, i.e., the saturation of water in the soil. Methods: We investigated the change of precipitation to runoff through the correlations between the characteristics of the soil and its vegetation. We applied the Curve Number (CN) method introduced by the United States Soil Conservation Service (USSCS); this represents an empirical model, which relates the vegetation cover to the geological and topographic conditions of the soil. Along with the geographic information system, the model allows to represent the variation of runoffs for each micro-basin, according to the different land use categories, over the time frame from 2010 to 2014. Results: We found that the maximum retention potential is directly affected by CN values, representing the runoff potential. Highest values of 100 belong to the wetlands, urban area, snow, and water, as rain is converted directly into runoff, being impervious areas. The Guano river micro-basin possesses clay soil with CN of 78, the soil texture for eucalyptus forest is clay loam, and its CN value, 46, is the lowest of the data set. Knowledge of field capacity allows to properly evaluate the storage capacity of soil and water conservation. Conclusions: Results of this work will be useful in the quantification of the water balance, to determine the water supply and demand.

IThe development of sound research is of the highest importance in developing countries within the context of natural resources preservation. The National Institute for Forestry Agricultural and Livestock Research of Mexico has supported an initiative for developing research in experimental -low instrumented watersheds of northern Mexico. In the past few years information on watershed´s response to rainfall has been monitored and transferred to users for best management of their rangelands. Alternatives for increasing rainfall productivity have been studied through rain fed and runoff agriculture experiments. Research results coupled with ranchers experience have merged together in a decision support system (expert system) for the better management of natural resources.
