MODFLOW-2000

MODFLOW is a three-dimensional finite-difference ground-water model that was first published in 1984. It has a modular structure that allows it to be easily modified to adapt the code for a particular application. Many new capabilities have been added to the original model. OFR 00-92 (complete reference below) documents a general update to MODFLOW, which is called MODFLOW-2000 in order to distinguish it from earlier versions. MODFLOW-2000 simulates steady and nonsteady flow in an irregularly shaped flow system in which aquifer layers can be confined, unconfined, or a combination of confined and unconfined. Flow from external stresses, such as flow to wells, areal recharge, evapotranspiration, flow to drains, and flow through river beds, can be simulated. Hydraulic conductivities or transmissivities for any layer may differ spatially and be anisotropic (restricted to having the principal directions aligned with the grid axes), and the storage coefficient may be heterogeneous. Specified head and specified flux boundaries can be simulated as can a head dependent flux across the model’s outer boundary that allows water to be supplied to a boundary block in the modeled area at a rate proportional to the current head difference between a “source” of water outside the modeled area and the boundary block. MODFLOW is currently the most used numerical model in the U.S. Geological Survey for ground-water flow problems. In addition to simulating ground-water flow, the scope of MODFLOW-2000 has been expanded to incorporate related capabilities such as solute transport and parameter estimation.

MODFLOW is free and can be download from USGS website.

MODFLOW is DOS program. There are numerous WIndows-based Graphical User Interfaces (GUIs) for MODLFOW. You can find a few here.

    Dear sir,
    i am a lecturer in Sarawak university malaysia and i found that Modflow is a very useful software for ground water flow estimation and modeling. I hope i may be provided the same alongwith the mannual guide.
    best regards

      Sir i am a student of University of Engineering and Technology peshawar pakistan , with due respect sir i am doing the BS final year project on MODFLOW software but unfortunately i have lake of its free version , Is there is any source or any other clue to gain its trail or free version , not a demo, thanks for reading me

    Dear sir,
    i am a student of master i am doing my master in water resources management from gec surat and i am doing research on sea water intrusion in coastal aquifer and i found that Modflow is a very useful software for ground water flow estimation and modeling. I hope i may be provided the same alongwith the mannual guide.
