Recognition is developing that a synergistic integration of knowledge and methods from a variety of allied disciplines are needed to study, engineer for, or manage water resources. Until recently, this comprehensive investigative approach was limited in part due to the lack of appropriate technologies. Recent advances in computer, communication, and information technologies have led to an increasingly pervasive and sophisticated cyberinfrastructure (CI) that enables integration in a common digital environment using remote and in-situ measurements with geotemporal databases and high-performance computational models.
