Starting July 1, prices reflect increases to keep up with the increases in our costs to maintain and release secure, professional software.
We continue to offer lower prices for additional seats, renewals, multi-year licenses, and academic licenses.
Maintenance fees for administrative costs of providing licenses are now listed separately; previously they were bundled with the license cost.
License revenues continue to support maintaining and updating the software, providing releases and patch releases, issue tracking, and compliance with secure code development standards. The University is a not-for-profit entity, so revenues are wholly dedicated to providing high quality software to support effective water management.
- One seat on a single node license allows multiple simultaneous executions on a single machine by the same user.
- A floating license may be installed on a server that serves the license files to machines that the server recognizes as being on its network.
- A floating license may have one or multiple seats, allowing one or more machines on the network to execute RiverWare simultaneously.
- Licenses can include combinations of single node seats and seats on a floating license.
- License prices are determined by number of seats with discounted prices for multi-year purchases. Renewal rates are discounted from initial year rates.
- Maintenance fees cover our costs for administration of licensing, generating licenses and providing assistance to users for installing the software. Note that maintenance fees were previously bundled into the listed license prices but are now independently itemized for transparency. See the tables below for details.
Additional seats can be added only by the same organization at the same location as the first seat.
System Requirements: Windows 10 and later. See details of system requirements.
Hardware dongle keys may be purchased for $300. For details on use, see page 23 of the Installation and License User's Guide.
Ask about discounts for countries with lower-income economies.
