Abstract
The Effect of Anisotropic Permeability on the Temperature Profiles Obtained In a River Discharge Scenario to a Deep Aquifer
Highlights
The interaction between surface and deep water bodies, between rivers and their underlying aquifers, is a topic of great interest in hydrogeology due to its importance for the storage and maintenance of underground water resources
Its study covers the mechanical problem of the investigation of 2D patterns of water flow, dependent on the contour conditions of hydraulic potential and soil permeability, and extends to the temperature patterns determined by the coupling between water flow and heat transport imposed by temperature conditions at the surface and at the bottom of the domain
The study of vertical temperature profiles has recently been used in the form of an inverse problem to determine recharge-discharge rates that are difficult and expensive to obtain by other means (Duque et al [4])
Summary
The interaction between surface and deep water bodies, between rivers and their underlying aquifers (the object of this work), is a topic of great interest in hydrogeology due to its importance for the storage and maintenance of underground water resources. The boundary conditions of constant piezometry of the river, large permeability at the bottom of the aquifer, and free condition at the right edge produce 2D flow patterns in which the development region of the linear (mean temperature) profile can be clearly distinguished.
