Hardware Requirements and Recommendations
The typical hardware equipment for the Microsoft Windows or Linux installation includes:
Intel Pentium III/800 MHz or higher (or compatible).
512 MB of memory minimum.
1 GB of memory recommended.
120 MB of available hard disk space for installation.
1024x768 minimum screen resolution.
Significantly more resources may be needed depending on your application. The minimum equipment for either operating system will be suitable for event simulation with basin models containing only 20 or 30 hydrologic elements. However, you will need better equipment if you intend to build basin models with over a hundred elements, perform continuous simulation for long time windows, or use the ModClark gridded transform method. For intense applications you should consider a multiple processor system running at 2.0 GHz or faster, and 1 GB or more of physical memory.
