Method for indirect determination of soil parameters for numerical simulation of dikes and earth dams

open access: yesApplied Water Science, 2022
One of the most important steps in the numerical simulation of a hydrogeological system is the precise definition of initial and boundary conditions. The better these are characterized, the more efficient the calculation and the more accurate are the ...

Resolution-Dependent Multifractal Characteristics of Flow in Digital Rock Twin Simulated Using the Lattice Boltzmann Method

open access: yesGeofluids, 2023
Digital rock twins are widely used to obtain hydraulic properties of porous media by simulating pore-scale fluid flow. Multifractal characteristics of pore geometry and flow velocity distribution have been discovered with two-dimensional (2D) images and ...

Optimal location of cutoff walls for seawater intrusion

open access: yesApplied Water Science, 2021
In this paper, the simulation–optimization method is used to study the optimal location of cutoff walls for seawater intrusion. The optimization model is based on minimizing the chlorine concentration of two water sources after 50 years.

Attention U-Net as a surrogate model for groundwater prediction [PDF]

open access: yesAdvances in Water Resources, Volume 163, May 2022, 104169, 2022
Numerical simulations of groundwater flow are used to analyze and predict the response of an aquifer system to its change in state by approximating the solution of the fundamental groundwater physical equations. The most used and classical methodologies, such as Finite Difference (FD) and Finite Element (FE) Methods, use iterative solvers which are ...
