![]() ![]() La longitud de riego o del gasto de riego. Selección del caudal de riego inapropiado, causada por el diseño incorrecto de Uno de los principales problemas es la pérdida considerable, por la Key words: gravity irrigation Green and Ampt equation irrigation tests kinematic wave modelĮl método de riego por gravedad es el más utilizado en los 85 Distritos de Riegoĭe México. Increased the average efficiency from 53 to 85 %. Savings was 2000 m 3 ha -1 per irrigation event, which The irrigation times decreased in averageġ1.76 h ha -1 per irrigation event and, in addition, the average With theĪpplication of the optimal flow rate of calculated irrigation, the irrigationĭepths decreased in average 19.63 cm, and in some cases, an in water depth of up Was validated with the complete Saint-Venant and Richards model. Used and the optimal flow rate was calculated with an analytical formula, which ![]() Were calculated from the advancement, storage and recession phases of each test.įor the simulation process of the superficial flow, the kinematic wave model was With an optimizationĪlgorithm, the parameters of the Green and Ampt Measured in the plots: slope, furrow width, entry flow rate, initial moistureĬontents, and for saturation and apparent density. In each irrigation test, the following variables were In this study, 197 irrigation tests were evaluatedĪnd designed, in eight textures, in Irrigation District 085, La Begoña, That with this flow rate, the gross historical water depth applied in the plotsĮvaluated could be decreased. Was to demonstrate that from the evaluation of an irrigation test, the optimalįlow rate can be calculated for each furrow during irrigation from data obtainedįrom the plot and the net irrigation depth to be applied. ![]() The selection of the inappropriate irrigation flow. Incorrect design of the irrigation longitude or the irrigation flow rate, from One of the main problems is the considerable loss caused by the The gravity irrigation method is the most frequently used in the 85 Irrigation Districts in ![]()
