Error Control of Iterative Linear Solvers for Integrated Groundwater Models

open access: yes, 2010
An open problem that arises when using modern iterative linear solvers, such as the preconditioned conjugate gradient (PCG) method or Generalized Minimum RESidual method (GMRES) is how to choose the residual tolerance in the linear solver to be ...

Groundwater flow simulation for artificial recharge: a GIS, remote sensing, and MODFLOW integration

open access: yesWater Practice and Technology
Groundwater (GW) emerges as a sustainable resource to meet water demand, yet current GW reservoirs fall short of projected population needs. Artificial GW recharge, bolstered by Geographical Information System (GIS) and Remote Sensing (RS) technologies ...

Application of MODFLOW and MT3DMS Models to Evaluate Groundwater Quantity and Quality in Northern Iran [PDF]

open access: yesJournal of Hydraulic and Water Engineering
In recent decades, climate change and drought have led to an increase in groundwater use in the world. In Iran, due to being in the global dry belt and also the impact of climate change, reduced rainfall and surface water, excessive use of groundwater ...
