- MODFLOW es un modelador de flujo por diferencias finitas desarrollado por el Servicio Geológico de los Estados Unidos, el cual consiste de un código fuente que resuelve mediante interacciones la . Se usa en hidrogeología para simular el flujo subterráneo de cualquier acuífero. El programa es de código libre, escrito principalmente en Fortran, y puede ser compilado y corrido en los sistemas operativos DOS, Windows o Unix. Desde que el modelo original fue desarrollado en los años 80 el Servicio Geológico de los Estados Unidos lo considera como un código estándar para simulaciones de acuífero. Actualmente se ha desarrollado algunas interfaces gráficas para MODFLOW. (es)
- MODFLOW is the U.S. Geological Survey modular finite-difference flow model, which is a computer code that solves the groundwater flow equation. The program is used by hydrogeologists to simulate the flow of groundwater through aquifers. The source code is free public domain software, written primarily in Fortran, and can compile and run on Microsoft Windows or Unix-like operating systems. Since its original development in the early 1980s, the USGS has made six major releases, and is now considered to be the de facto standard code for aquifer simulation. There are several actively developed commercial and non-commercial graphical user interfaces for MODFLOW. MODFLOW was constructed in what was in 1980's called a modular design. This means it has many of the attributes of what came to be called object-oriented programming. For example, capabilities (called "packages") that simulate subsidence or lakes or streams, can easily be turned on and off and the execution time and storage requirements of those packages go away entirely. If a programmer wants to change something in MODFLOW, the clean organization makes it easy. Indeed, this kind of innovation is exactly what was anticipated when MODFLOW was designed. Importantly, the modularity of MODFLOW makes it possible for different Packages to be written that are intended to address the same simulation goal in different ways. This allows differences of opinion about how system processes function to be tested. Such testing is an important part of multi-modeling, or alternative hypothesis testing. Models like MODFLOW make this kind of testing more definitive and controlled. This results because other aspects of the program remain the same. Tests become more definitive because they become less prone to being influenced unknowingly by other numerical and programming differences. (en)
- MODFLOW软件是由美國（USGS）發展之地下水數值模式，為有限差分法開發之三維飽和地下水流數值模式，其為Modular three-dimensional groundwater flow model之縮寫，最早版本於1988年发布。本软件為目前最被廣泛使用之地下水模式之一，可以應用於飽和地下水流問題，在時間方面不論是穩態（steady）抑或是非穩態（unsteady）均可使用；在分層上，承压含水層（confined aquifer）與非承压含水層（unconfined aquifer）均可模擬。其控制方程式表示如下： 目前釋出版本已有MODFLOW 88、MODFLOW 96、MODFLOW 2000、MODFLOW LGR、MODFLOW 2005等等版本，由於模式設計模組化，因此目前有許多模組可供使用。 (zh)
