MODAC

MODAC is a specialized Education tool falling under the Science Tools subcategory, primarily designed for hydrogeology-based parameter estimation in groundwater flow models. The latest version, 1.40, was developed by Guo and Zhang and is available for free download. The executable file for the software is MODAC.EXE and it is compatible with a wide range of operating systems including Windows XP, Vista, 7, 8, 10, and 11.

The primary function of MODAC is to aid in the calibration of groundwater flow models by employing parameter estimation methods. It integrates the three-dimensional groundwater flow model MODFLOW, utilizing the inverse hydraulic parameter estimation procedures devised by Guo and Zhang during the mid-90s and early 2000s. This powerful synergy makes MODAC a unique and indispensable tool for groundwater flow model calibration.

For users interested in previous iterations, other versions of the program like 1.6, 1.5, and 1.4 are also available. The freeware status of the program ensures that users can access it without any financial commitment, making it an attractive solution for students and professionals alike in the field of hydrogeology.

Pros:

• Freeware: No cost involved, making it accessible for educational purposes and professional use alike.
• Supports a wide range of Windows OS versions, ensuring compatibility with both modern and legacy systems.
• Combines the robust MODFLOW model with specialized hydraulic parameter estimation procedures from reputable developers.

Cons:

• As its primary focus is hydrogeology, it might not be useful for other scientific or educational purposes outside this niche.
• Lacks modern user-interface features that newer software might provide, given its integration with the 1996 version of MODFLOW.
