Abstract

Trifa is the most productive agricultural plain of northeastern Morocco The development of agricultural activities during the last few decades has been mainly based on imported water for irrigation However irrigation requirements have become so large that groundwater is used as a secondary source to supply the agricultural and domestic water needs causing a depletion of the groundwater resources especially during dry periods A hydrological and a hydrogeological model for the Trifa plain have been developed which yield information on relevant parameters such as groundwater recharge and estimate the amount of pumped groundwater needed to meet the irrigation needs The models MODFLOW and WetSpass provide insight into the status and evolution of the groundwater reserves The results of the study are useful to predict the sustainability of the groundwater resources in the Trifa plain and to evaluate possible management actions A reduction in groundwater abstraction by at least 25 may be necessary to achieve sustainable conditionsTrifa est la plaine agricole la plus productive du NordEst marocain Le développement de l’activité agricole durant ces dernières décennies a essentiellement reposé sur l’irrigation Néanmoins les besoins de l’irrigation sont devenus tels que l’eau souterraine est utilisée comme ressource secondaire pour combler la demande en eau domestique et agricole induisant un rabattement d’autant plus important durant les périodes sèches Un modèle hydrologique et hydrogéologique de la plaine de Trifa a été développé sur base des paramètres les plus importants tels la recharge et permet d’estimer le pompage nécessaire des eaux souterraines pour combler les besoins de l’irrigation Les modèles MODFLOW et WetSpass apportent une bonne connaissance de l’état et de l’évolution des réserves souterraines Les résultats de l’étude sont utiles pour prédire la longévité des ressources et pour évaluer différents scénarios de gestion Une réduction de l’extraction de 25 serait nécessaire pour atteindre un état durableTrifa es la planicie agrícola más productiva del noreste de Marruecos El desarrollo de las actividades agrícolas durante las últimas décadas se ha basado principalmente en agua importada para riego Sin embargo los requerimientos de riego han llegado a ser tan grandes ocasionando que se utilice el agua subterránea como una fuente secundaria para abastecer las necesidades de agua para uso doméstico y agrícola lo que causa un agotamiento de los recursos de agua subterránea especialmente durante periodos secos Se ha desarrollado un modelo hidrogeológico e hidrológico para la planicie Trifa el cual aporta información de parámetros relevantes tal como recarga de agua subterránea y estima la cantidad de agua subterránea que necesita bombearse para satisfacer las necesidades de riego Los modelos MODFLOW y WetSpass aportan una idea acerca del estado actual y la evolución de las reservas de agua subterránea Los resultados de este estudio son útiles para predecir la sostenibilidad de los recursos de agua subterránea en la planicie Trifa y para evaluar posibles acciones de gestión Puede ser necesario reducir la explotación de agua subterránea en por lo menos 25 para alcanzar condiciones sostenibles
