Hydrologic Information System (HIS) — The CUAHSI HIS is a geographically distributed network of hydrologic data sources and functions that are integrated using web services so that they function as a connected whole.

Hydrologic Measurement Facility (HMF) — The main objective of a hydrologic measurement facility is to provide the equipment and training required for scientists to accurately collect the necessary data for their studies. A successful integrated, coherent, multi-scale, multidisciplinary dataset requires the acquisition of accurate and precise measurements. Recent advances in environmental sensors, wireless communications, remotely sensed data, GIS, and computers can benefit hydrologic science.

Hydrologic Observatory — Since the beginning of 2006, observatory development has focused on integrating activities among the various environmental disciplines interested in water-oriented observatories. Tangible results of CUAHSI's development of a Major Research Equipment and Facilities Construction (MREFC) initiative with the Environmental Engineering community, the WATer and Engineering Research System network (WATERS network) are awards for WATERS test bed sites. These two-year projects, which began in the Fall of 2006, will examine various aspects of observatories such as development of digital observatories, sensor network deployment, and data distribution. CUAHSI will assist in coordinating these projects and will be distributing results to the community.

Hydrologic Synthesis Activities — Recognizing the importance of water to life and to Earth systems, CUAHSI seeks to advance the full breadth of hydrologic science through interdisciplinary research aimed at synthesizing existing data and information. The integrative aspects are critical for hydrologic science, as water is the link between climate and ecosystems, humans and environments. These synthesis activities will be primarily conducted by working groups and the data will be made widely available.

Education & Outreach — The goal of the E&O Standing committee is to develop strategies for and descriptions of programs and initiatives that can provide education and outreach opportunities to any science initiatives that are to be included in the CUAHSI Science Plan.
