Abstract :
Lattice Boltzmann Method (LBM) has emerged as a fast, precise, and effcient
numerical solution to solve differential equations. There seems to be a lack of research
on the use of LBM to solve groundwater
ow in unconfined aquifers. Therefore, in this
study, considering the D2Q9 scheme, an innovative numerical solution based on LBM was
introduced to solve the groundwater
ow in unconfined aquifers. The solutions obtained
from the proposed LBM were compared to results that stemmed from three different
unconfined groundwater problems with known solutions. Both steady and transient
conditions for groundwater
ow were considered in simulations. The results showed that
the proposed LBM can satisfactorily simulate unconfined groundwater
flow.
