Hydrometeorology and Geospatial Analytics Lab
The hydrometeorology lab supports primarily research needs. It is equipped with a precipitation sensing radar installed on the roof or the Sciences Building (SB). Cloud and precipitation data are input into hydrological models for predicting flooding. The software for these simulations was developed under NOAA funding. The major pieces of equipment involved are:
- a radar
- two research rain gauges with batteries and data loggers
- two desktop computers and
- one laptop computer.
ArcGis software is installed in these computers used for GIS applications. Since 2006, a total of $39k has been invested for equipping this lab.
CEE faculty works closely with the Center for Water Research http://www.utsa.edu/water/ and other faculty from the UTSA College of Sciences to carry our research under the new Doctoral program in Environmental Science and Engineering.
