The CUAHSI Hydrologic Information System

CUAHSI Hydrologic Information System (HIS) is a system for publishing and accessing water data. This technology functions much like the websites that you browse on the internet:  Websites (like this one) are hosted on servers, which can be discovered through the use of a search engine catalog (like Google), and displayed using an internet browsing client (like Firefox).  In the CUAHSI HIS, water data from a variety of sources are hosted on servers (HydroServers), are catalogued into a central metadata database  (HIS Central), and are discoverable through the use of client applications (such as HydroClient).

The Hydrologic Information System was developed through an NSF-funded research project led by Dr. David Maidment (University of Texas at Austin). This project concluded in 2011. Since that time, CUAHSI has maintained, and continued development on, the HIS infrastructure. For more information, visit the Legacy Tools page on the CUAHSI website.
