摘要
从阿尔托米拉山脉第一批水生系统的定义到目前MASB地下水体的划分,该山脉分化的水生动物在其范围和概念水文地质模型方面不断发生变化。即使在今天,在水文地质层面上,其内部划分也存在不确定性。根据对今天构成MASB渗透层的沉积结构的起源和形成的深入结构分析,得出的构造模型与MASB Sierra de Altomira的水文地质,特别是其可能的内部划分有关。获得的结构模型区分了在局部范围内表现出不同水文地质行为的不同区域。拟议的分区是在区域一级进行的,区分了两个主要的结构块:北部、南部和更大的规模,将基本水文地质单元(UHB)定义为一个最小可分割单元,其中确定了概念水文地质模型的所有组成部分。该部门是随后解释阿尔托米拉山脉MASB当地水文地质功能的重要起点,尽管这一建议需要进行补充研究,以更好地了解其水动力学。从阿尔托米拉山脉第一个含水层系统的定义到目前的地下水体划分,该地区定义的含水层的范围和概念水文地质模型不断发生变化。即使在今天,其在水文地质层面的内部划分也存在不确定性。通过对今天构成GWB可渗透水平的沉积结构的起源和形成进行深入的结构分析,得出的构造模型与Altomira GWB山脉的水文地质,特别是其可能的内部共享有关。最终的结构模型使我们能够区分不同的区域,对当地水文地质产生影响。这确定了具有不同水文地质行为的部门。拟议的分区是在不同级别进行的,从两个大型的北部和南部结构块到将基本水文地质单元(BHU)定义为一个最小可分割单元,在该单元中识别水文地质概念模型的所有组成部分。该司是随后在当地确定Altomira GWB山脉水文地质功能的重要起点,尽管这一建议需要进行补充研究才能完全确定。
Propuesta de compartimentación estructural en la MASb 041.001 Sierra de Altomira:implicaciones hidrogeológicas
espanolDesde la definicion de los primeros sistemas acuiferos en Sierra de Altomira hasta la actual division en masas de agua subterranea MASb, los acuiferos diferenciados en esta sierra han sufrido constantes modificaciones en su extension y modelo hidrogeologico conceptual. Incluso en la actualidad se plantean incertidumbres con respecto a su compartimentacion interna a nivel hidrogeologico. A partir de un profundo analisis estructural sobre el origen y formacion de las estructuras sedimentarias que hoy constituyen los niveles permeables de la MASb, se ha correlacionado el modelo tectonico resultante con la hidrogeologia de la MASb Sierra de Altomira en general, y con su posible compartimentacion interna en particular. El modelo estructural obtenido ha permitido distinguir diferentes zonas que, a escala local, presentan un comportamiento hidrogeologico diferente. La compartimentacion propuesta se realiza a nivel regional, diferenciando dos grandes bloques estructurales: septentrional, meridional y, una escala mayor, con la definicion de la Unidad Hidrogeologica Basica (UHB) como unidad minima divisible en la que se identifican todos los componentes del modelo hidrogeologico conceptual. Esta division supone un importante punto de partida para la posterior interpretacion del funcionamiento hidrogeologico local de la MASb Sierra de Altomira, si bien esta propuesta requiere de estudios complementarios para un mejor conocimiento de su hidrodinamica.
