FAQ

Is there an annual maintenance fee?

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 will 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.

How long before I receive my activation code?

Our online store is fully automated, so you will receive your activation codes instantly via email after you place an order by credit card or PayPal.

If for some reason you have not received your email please contact us to find out the status of your order.

How do I get the updates?

If you add the annual maintenance to your order it’s automatic. Your software will check for new updates each time it’s launched. If one is available, you will be prompted to update. Just click [Ok] and seconds later your software will start as usual, but will be the latest version.

What’s the difference between Single-Seat and Unlimited Site licenses?

Both licenses are perpetual. They never expire. The Single-Seat allows for a single installation and can be run only on one PC. The Unlimited Site License allows you to install and run the software, concurrently, on any number of PCs at your physical site. Several users can be operating the software at the same time.

If I purchase a Single-Seat license today can I upgrade it later to a Site license?

Yes. You can upgrade your Single-Seat purchase anytime to a Site License. Just order the Site License Upgrade on this page. Within 24 hours of your purchase your existing Activation Code(s) will be converted to a Site License where you can install and activate as many seats at your location as you wish.

How do I install the software?

Installation is a piece of cake. Just click on any of the “Download Free Trial” links throughout this website. You’ll be asked to first setup your account with a username, password, etc. After that, just click the [Install] button.

The software will automatically download and install itself… takes only seconds. You’ll see a new shortcut icon on your desktop and you’ll be ready to run the software.

Stormwater Studio, Channel Studio and Culvert Studio will automatically open with a sample project for you to play around with.

Do I have to install a license server to manage the Site license?

No. Everything is managed on our end. What’s even better is that you’ll be able to use a single activation code for all of your installations. An internet connection is required at the time of activation.

What forms of payment can I use to purchase?

We accept all major credit cards including Visa, MasterCard, American Express, Discover, checks and PayPal.

I'm still not convinced. Why should I buy Hydrology Studio?

Think Chevrolet. What immediately comes to mind? Having trouble? It’s understandable. Chevrolet is a large, small, cheap, expensive car, suv… or truck. Is it any wonder that today GM is closing the doors on plants right and left? When you try to be everything to everybody, you’re nothing to nobody. You’re spread so thin that you produce mediocre products at best. Do any large, unfocused engineering software vendors come to mind?

On the other hand, BMW is opening new plants. They are narrowly focused on one thing, “The ultimate Driving Machine”.

Hydrology Studio is also a narrowly focused company that believes in doing one thing really well… stormwater modeling software. That’s it. We produce five closely-related products. Not one hundred and thirty-five. Our focus allows us to produce software that users like.

So, what would you rather drive, a Chevrolet or a BMW?
