Приєднався 25 кві 2022
The overall scientific objective of the Hydrogeology Group (GHS) (“mission”) is to contribute to the good status of groundwater through increased understanding of aquifer processes, the development of tools and concepts for characterization and management, and the application of these tools and understanding to the solution of groundwater related societal problems. This overall goal is achieved through four basic research lines that address the hottest issues in groundwater hydrology and feed tools and concepts to applied lines. These lines are: Stochastics and heterogeneity; Transport; Modeling.The applied research lines are: Nature-Based solutions for wastewater treatment; seawater intrusion and submarine groundwater discharge; hydro-bio-geo-chemical tools; Groundwater resources management; pore-scale processes; circular economy, social considerations and Sustainable Development Goals.
MODELING OF FLOW AND REACTIVE TRANSPORT IN POROUS MEDIA TOSIMULATE THE EVOLUTION OF FLOW FIELD

Groundwater Hydrogeology and geochemistry webinar.
Autor:
Abhijit Chaudhuri (Indian Institute of Technology Madras, Chennai)
Título:
Coupled modeling of flow and reactive transport in porous media to
simulate the evolution of flow field
Abstract:
Reactive transport in porous media may lead to various interesting
evolution of flow pattern in subsurface system e.g.
dissolution/precipitation of mineral results in the alteration of flow
paths, concentration dependent density and viscosity causes flow
instability etc. In this seminar I will first present some results
related to complex flow field evolutions in natural and engineered
subsurface systems. It will be followed by brief presentation of our
ongoing research on reactive transport modeling related to membrane
filtration, coupled flow and geomechanics, etc.

Excelente presentación, muy interesante!
Muchas gracias por tu amable comentario! saludos.
Porqué enfocarnos en recargar los acuiferos con agua tratada, pudiendo recargarlos con agua destilada naturalmente, o sea con lluvia, esto saneará los acuiferos, recuperará los niveles de los mantos freáticos y además dará disponibilidad de agua dulce a cualquier agricultor o ganadero, o industria que quiera utilizar agua, bombeandola a bajo costo energético, casi superficial, reactivando pozos y norias que se han secado.
Además evitará los problemas de arsénico y flúor presentes en el agua que se está extrayendo. Estamos haciendo prácticamente solo recargas inducidas con el riego, y esta agua arrastra fertilizantes y químicos de los insecticidas.
Deberíamos enfocarnos en enseñar a ganaderos y agricultores como infiltrar el agua de lluvia, en vez de dejarla que se pierda por evaporación, eso solucionaría el cambio climático, el calentamiento global y la disponibilidad de agua potable, se los dejo de tarea.
