Abstract/Description: In the Trans-Pecos basin that covers parts of New Mexico and Texas, pecan (Carya illinoinensis (Wangenh.) K. Koch) is a major irrigated cash crop. Flood irrigation is the dominant method of irrigation to pecan crop and amount of water varies widely within the region ranging from 1.22 to 3.05 m y-1. Elevated salinity is a major challenge to the irrigated agriculture in the region and growers apply excess irrigation by flood method to push the salts below root zone. Consumptive water use for mature pecan crop is far lower than the current irrigation amounts and there may be opportunities to improve water use efficiency to extend freshwater supply by adapting improved irrigation methods such as drip. However, growers are concerned that reduced water application will resulted in salt accumulation in the rootzone. This study conducted in a 1300-acre pecan orchard evaluated the effects of irrigation methods (flood and drip irrigation) on root zone salinity. Results of the study indicated potential for improving water use efficiency without impairing pecan nut yield and increasing soil salinity.

SIMULACIÓN DEL AGUA SUBTERRÁNEA EN ACUÍFEROS CUYO PRINCIPAL USO ES EL ABASTECIMIENTO PÚBLICO URBANO. CASO DE ESTUDIO: ACUÍFERO VALLE DE JUÁREZ

Abstract/Description: El agua subterránea en el planeta tierra es cada vez más escasa y a mediada que la población crese, aumenta también la demanda de agua, para uso público urbano. En la zona norte de la república mexicana se localiza el estado de Chihuahua, el cual se abastece principalmente del agua subterránea, lo que ha provocado que, de los 61 acuíferos de esta región, 30 presenten un déficit en su disponibilidad. El principal usuario del agua subterránea es la agricultura, por lo que los acuíferos que presentan mayor déficit están localizados en zonas mayormente agrícolas. Sin embargo, existen algunos acuíferos como el de Chihuahua-Sacramento (CHS) y El Valle de Juárez (VJ), donde la agricultura no representa el principal usuario del agua subterránea si no el uso público urbano. Estos acuíferos presentan al año 2018 un déficit en su disponibilidad de -57.7 hm3/año para el CHS y de -86.2 hm3/año para VJ. Ambos, son una muestra de que también los acuíferos cuyo uso principal sea el abastecimiento público urbano, pueden presentar un déficit si no se administran adecuadamente. El objetivo de esta investigación fue determinar las variaciones de las cargas hidráulicas y del almacenamiento al mantener o disminuir la extracción del agua subterránea en una porción del acuífero Valle de Juárez. Para ello se construyó el modelo de una porción del acuífero, utilizando Modflow. El modelo abarca una superficie de 711 km2, comprendido entre las coordenadas WGS84 UTM Zona 13, 3’476,100 a 3’518,500 Norte y 345,500 a 383,500 Oeste. Se usaron 2 capas, 27 zonas de conductividad hidráulica y almacenamiento, 7 zonas de recarga, 196 pozos de bombeo cuyo uso principalmente es para el abastecimiento público urbano y 370 observaciones piezométricas. El modelo se construyó en estado transitorio. Una vez calibrado el modelo, se simularon las cargas hidráulicas hasta el año 2070. En el escenario 1, el bombeo se mantuvo constante y en el escenario 2, se varió el bombeo desde el año 2018 a 2070. Los resultados muestran para el escenario 1 que los pozos se abaten continuamente y la pérdida de almacenamiento alcanza los 7,793 hm3. Para el escenario 2, a partir del año 2040 se observa algunas pequeñas recuperaciones del nivel del agua subterránea en algunos aprovechamientos y a medida que avanza el tiempo hasta el año 2070, son más los aprovechamientos que presentan una recuperación. Lo anterior lo evidencia el almacenamiento, ya que a partir del año 2040 la pérdida de almacenamiento comienza a disminuir, por ejemplo, entre el año 2030 y 2040 se perdieron 818.6 hm3, del 2040 al 2050 fue de 573 hm3, del 2050 al 2060 de 205.45 hm3 y finalmente del 2060 al 2070 su valor fue de -162 hm3, que corresponde a una ganancia neta del almacenamiento.
