Tidal fluctuations and spatial heterogeneity lead to trapping and chaotic mixing in coastal aquifers [PDF]

open access: yesarXiv
The combined effect of tidal forcing and aquifer heterogeneity leads to intricate transport patterns in coastal aquifers that impact both on solute residence times and mixing dynamics. We study these patterns through detailed numerical simulations of density-dependent flow and transport in a three-dimensional heterogeneous coastal aquifer under tidal ...

Acuíferos en Chihuahua: estudios sobre sustentabilidad

open access: yesTecnociencia Chihuahua, 2019
El manejo no sustentable de acuíferos puede manifestarse como un déficit (recarga-extracciones), el cual se refleja en un descenso del nivel potenciométrico con respecto al tiempo, y también en el deterioro en la calidad del agua. Una manera
