MODFLOW-SURFACT Flow groundwater simulation software features many robust methods and enhanced simulation capabilities for handling complex saturated/unsaturated subsurface flow and transport processes. Based on the USGS modular groundwater flow model, MODFLOW.

Overview

MODLFOW SURFACT Features & Highlights

Dynamic memory allocation permits unlimited problem dimensions

Modular structure allows further development of additional simulation capabilities to provide a comprehensive, general purpose simulator within the MODFLOW framework

Benefits of MODFLOW SURFACT​

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

Prevents water table buildup beyond a specified recharge-ponding elevation

Handling of seepage face boundary conditions

Adaptive time-stepping schemes automatically adjusts time-step size to the non-linearities of the system to optimize the solution stability

Robust and efficient Pre-conditioned Conjugate Gradient matrix solver

Capability of modeling unsaturated water or air movement

Enhanced Newton-Raphson linearization option increases robustness for unconfined and/or unsaturated flow conditions

MODFLOW-SURFACT地下水流模擬軟件有許多強大的功能和分析程序,能有效模擬三維水流、處理複雜飽和/非飽和的地下水流動和運移過程,擁有高級的仿真能力。是依據美國地質調查局的模組化地下水流模型來設計的軟體。

MODLFOW SURFACT特點

動態內存分配允許無限制的尺寸問題

模組化結構使更多的模擬功能進一步發展,在MODFLOW的框架下提供全面通用的模擬器​
