Frente a estas presiones sobre los recursos h\u00eddricos y ante un crecimiento de la demanda agraria en torno a un 33% en los pr\u00f3ximos 40 a\u00f1os, se hace necesario el planteamiento de una modificaci\u00f3n en la independencia del uso de recursos llevada hasta el momento. Debido a la interrelaci\u00f3n que existe entre aguas subterr\u00e1neas y superficiales, as\u00ed como de la exigencia l\u00f3gica de considerar el uso conjunto y\/o alternado de ambas, el agua se debe analizar como recurso \u00fanico. las ventajas que representa el uso conjunto de los embalses superficial y subterr\u00e1neo, consisten fundamentalmente en alcanzar unas garant\u00edas de suministro cercanas al 100%, con un costo relativamente bajo. Obtener estas garant\u00edas con embalses de superficie \u00fanicamente tendr\u00eda un costo excesivamente elevado y la mayor parte de las veces no rentable. se ha seleccionado el municipio de hell\u00edn como aplicaci\u00f3n de estas consideraciones, ya que pr\u00e1cticamente, la totalidad del mismo se asienta sobre masas de aguas subterr\u00e1neas (95,94%), hecho que resalta la gran importancia que tienen los acu\u00edferos y sus recursos asociados con el desarrollo y la actividad econ\u00f3mica de la zona. En este sentido, se han evaluado las distintas alternativas que ofrece el t\u00e9rmino en relaci\u00f3n con los recursos disponibles, tanto superficiales como subterr\u00e1neos, as\u00ed como las aportaciones y demandas asociadas, la localizaci\u00f3n geogr\u00e1fica y la posibilidades de interrelaci\u00f3n entre recursos superficiales y &quot;embalses&quot; subterr\u00e1neos.  Adem\u00e1s, los regad\u00edos que se abastecen con aguas procedentes del r\u00edo mundo a trav\u00e9s del llamado canal de hell\u00edn, son los que tienen mayor importancia en el municipio (38%), seguido por las aguas subterr\u00e1neas que representan el 34,51% del total de la superficie. Ambas unidades abarcan m\u00e1s del 70% de la superficie de regad\u00edo de hell\u00edn, lo que da una idea de los posibles beneficios de la integraci\u00f3n y regulaci\u00f3n de los recursos utilizados por ambas.  Este canal atraviesa en el \u00faltimo tramo de su recorrido el l\u00edmite sur del llamado acu\u00edfero del boquer\u00f3n, lo que lo hace id\u00f3neo para que funcione como embalse regulador del sistema local, recibiendo los excedentes de los recursos superficiales del citado canal y aportando parte de los vol\u00famenes demandados, participando activamente en la regulaci\u00f3n del sistema h\u00eddrico asociado.  metodolog\u00eda una vez determinadas las posibilidades del sistema de gesti\u00f3n h\u00eddrica que se pretende analizar, se han evaluado las distintas alternativas planteadas (gesti\u00f3n independiente actual y gesti\u00f3n conjunta) mediante la aplicaci\u00f3n de simges. Este modelo, desarrollado por la universidad polit\u00e9cnica de Valencia, permite la incorporaci\u00f3n de acu\u00edferos al subsistema de agua superficial como un &quot;dep\u00f3sito&quot; m\u00e1s de regulaci\u00f3n, que almacena agua durante \u00e9pocas de excedentes y la suministra, cuando existe d\u00e9ficit. Para los subsistemas superficiales el flujo es calculado simplemente por continuidad o balance, mientras que para el subsistema subterr\u00e1neo, representado por el acu\u00edfero del boquer\u00f3n, se ha empleado el modelo distribuido de flujo lineal que proporciona aquival, integrado en el mismo paquete que el simges (aquatool).  resultados la simulaci\u00f3n confeccionada caracterizando el sistema de gesti\u00f3n h\u00eddrica actual sin interconexi\u00f3n entre los recursos superficiales y subterr\u00e1neos  pone de manifiesto la insostenibilidad en el ritmo de explotaciones que se realizan sobre el acu\u00edfero del boquer\u00f3n a medio plazo, debido a una bajada en los niveles piezom\u00e9tricos locales que superar\u00edan la capacidad de las infraestructuras de extracci\u00f3n instaladas. Alcanzada la profundidad m\u00e1xima de los sondeos, todas las comunidades de regantes de la zona se ver\u00edan afectadas directamente en las dotaciones asignadas, reduci\u00e9ndose dr\u00e1sticamente las garant\u00edas y, consecuentemente, la rentabilidad de la producci\u00f3n asociada. sin embargo, en el escenario que refleja la gesti\u00f3n conjunta se demuestra que la recuperaci\u00f3n de los niveles piezom\u00e9tricos es casi inmediata en las proximidades  de la zona de recarga, as\u00ed, como la amortiguaci\u00f3n de las bajadas en el resto del acu\u00edfero. Esto asegura un mantenimiento de las explotaciones actuales a medio y largo plazo, as\u00ed como un aumento de las garant\u00edas de suministro de todas las comunidades de regantes relacionadas directa e indirectamente con el acu\u00edfero regulador del sistema.   objetives in the 90&apos;s, spain has reached what is known as water maturity, that is to say, that its total water demand has exceeded half of its resources. Opposite to these pressures on the water resources and before a growth of the agrarian demand concerning 33% in the next 40 years, the exposition of a modification becomes necessary in the independence of the use of water resources taken up until now. Due to the relationships between underground and superficial water, as well as of the logical demand of considering the joint and\/or alternating use of both, water must be considered as a unique resource. the advantages of the joint use of the superficial and underground resources consist of reaching guarantees of supply near to 100 %, with a relatively low cost. Obtaining these guarantees only with surface resources would have a high cost and not profitable most of the times. the use of aquifers, as reservoirs of regulation, can focus, in addition to natural regulation (balance between natural recharge and extractions), as artificial one, in which the water earnings increase deliberately to the aquifer, by means of artificial recharges. This system allows &quot;to regulate&quot; waters that are not necessarily coming from the aquifer, and that would not have another opportunity to be useful. The artificial recharge uses the capacity of reservoir of the aquifer, refilling its empty spaces due to a natural process or the extractions. to verify these considerations hell\u00edn has been selected because almost the total of its surface settles on masses of groundwater (95,94 %), a fact that highlights the great  importance of aquifers and its resources associated with the development and the economic activity of the area. According to this, different available alternatives there have been evaluated, related to the joint use of resources, as well as the contributions and associate demands, the geographical location and the possibilities of interrelation between superficial resources and underground &quot;reservoirs&quot;. In addition, irrigations supplied by resources from the river mundo through the hell\u00edn channel, are the ones which have major importance in the municipality (38 %), followed by the ones that use groundwater resources that represents 34,51 % of the whole of the surface. Both units include more than 70 % of the surface of irrigation of hell\u00edn, what gives an idea of the possible benefits of the integration and regulation of the both resources. This channel crosses the boquer\u00f3n aquifer in its south limit near hell\u00edn, what makes possible the use of this aquifer as a regulatory reservoir of the local system, receiving the surpluses of the superficial resources of the channel and contributing part of the demanded volumes, taking part in the regulation of the local water resources management. methodology as soon as the possibilities of the system have been taken into account, the different alternatives have been analyzed (current independent management and joint management) by means of the application of simges. This model, developed by the university of Valencia, allows the aquifer to be incorporated in the surface water resources subsystem as one more regulation reservoir, which stores water during periods of surpluses and gives it, when deficit exists. In superficial subsystems the flow is simply calculated by continuity on balance and the underground subsystem has been represented by the use of the distributed model of linear flow that provides aquival, integrated into the same programme as the simges (aquatool). results the simulation characterizing the system of current water management without interconnection between the superficial and underground resources reveals the unsustainable rhythm of developments realized on aquifer in medium-term, due to descent in hydraulic levels which overcome the capacity of the installed infrastructures of extraction. Once the maximum depth of the wells is reached, all the communities of farmers of the area would turn out to be affected, diminishing drastically the guarantees and, therefore, the profitability of the associate production. nevertheless, the scene of the joint management demonstrates that the recovery of the hydraulic levels is almost immediate in the proximities of the area of recharge, and also the muffling of the descents in the rest of the aquifer. This ensures the maintenance of the current developments in long term, as well as an increase of the guarantees of supply of all the related farmer communities related to the aquifer.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Gesti\u00f3n conjunta de recursos h\u00eddricos a escala local. aplicaci\u00f3n del medelo simges al caso de
