Geological Survey. Growing interest in surface and groundwater interactions, local refinement with nested and unstructured grids, karst groundwater flow, solute transport, and saltwater intrusion, has led to the development of numerous MODFLOW versions. Often times, The XT3D option extends the capabilities of MODFLOW by enabling simulation of fully three-dimensional anisotropy on regular or irregular grids in a way that properly takes into account the full, three-dimensional conductivity tensor.
It can also improve Ground-water flow is simulated using a block-centered finite-difference approach. Layers can be simulated as confined or unconfined. Flow associated with external stresses, such as wells, areal recharge, evapotranspiration MODFLOW simulates steady and nonsteady flow in an irregularly shaped flow system in which aquifer layers can be confined, Compatible Hydrogeologic Software Offerings Waterloo Hydrogeologic offers intuitive and helpful 3rd party software that elevates and strengthens your project results.
Handles complete desaturation and resaturation of grid cells Accurate delineation and tracking of water table position, taking into account flow in the unsaturated zone, delayed yield, and vertical flow components.
Automatic and correct redistribution of the total flow rate of a well screened through multiple model layers when the upper cell s are pumped dry. Accommodation of wellbore storage and overpumped wells and prevents water table buildup beyond a specified recharge-ponding elevation.
Adaptive time-stepping schemes automatically adjusts time-step size to the non-linearities of the system to optimize the solution stability. Capability of modeling unsaturated water or air movement.
