Abstract
En el tercer ciclo de planificación (2022-2027), los planes hidrológi-cos de cuenca de algunas demarcaciones hidrográficas introducen im-portantes avances. Es el caso de la del Miño-Sil, en que se incluye una nueva delimitación de masas de agua subterránea más acorde con las especificaciones europeas y españolas en este sentido. En este trabajo se muestra una síntesis de los criterios seguidos en ente proceso, nece-sariamente adaptados a la singularidad geológica e hidrogeológica del territorio perteneciente a esta demarcación. De este modo, sin perder de vista los criterios marcados en las instrucciones vigentes, se han intro-ducido criterios como las divisorias hidrológicas, el tipo de porosidad y/o permeabilidad y la concentración de presiones significativas, entre otros. Como resultado, se obtiene una delimitación de MASb más fácilmente adaptable al proceso de planificación hidrológica, pero que aún tiene camino por recorrer a la hora de adaptar las redes de control a la nueva morfología y criterios de definición empleados
In the third planning cycle (2022-2027), the river basin mana-gement plans of some river basin districts introduce important ad-vances. This is the case of the Miño-Sil plan, which includes a new delimitation of groundwater bodies in accordance with the European and Spanish specifications in this regard. This work shows a synthe-sis of the criteria followed in this process, necessarily adapted to the geological and hydrogeological singularity of the territory belonging to this demarcation. Thus, without losing sight of the criteria set forth in the current instructions, criteria such as hydrological divisions, the type of porosity and / or permeability and the concentration of sig-nificant pressures, among others, have been introduced. As a result, a MASb delimitation is obtained that is more easily adaptable to the hydrological planning process, but which still has some way to go when it comes to adapting the control networks to the new morpho-logy and definition criteria used
