FAQ

Is there an annual maintenance fee with the Perpetual License?

Yes. It’s optional, but highly recommended. Hydrology Studio’s Maintenance is a simple, cost-effective way to make sure you are always on the latest version. You’ll receive automatic free software upgrades and priority technical support.

During your check-out you will be prompted to add Annual Maintenance to your cart. The annual cost is 20 percent of the purchase price. For example, the maintenance for Hydrology Studio is $99/yr.

How often do you upgrade the software?

Very often. You can expect an update on your software about every three months, provided you add the optional annual maintenance to your purchase at check-out.

What are the limitations of the Trial Versions?

The Trial versions have some minor functional limitations. For example, you will not be able to save any of your project files. All printed reports will be watermarked. There may also be limits as to the total number of hydrographs, pipes, channel sections, etc. However, you will certainly be able to give them a good test run. There is no time limit.
