http://RiverWeb.ncsa.uiuc.edu/ An alliance of the National Center for Supercomputing Applications (NCSA), the Geographical Modeling Systems Laboratory and History Department at the University of Illinois at Urbana-Champaign, the Illinois State Museum and several other prospective partners, RiverWeb is a multidimensional, multiscale, multidisciplinary, digital information architecture for the Mississippi watershed, a framework that will enable broad public access to and use of knowledge, tools and data required for integrated river management, wetland conservation and land use. As an unfolding program, RiverWeb will eventually include a web-based virtual exploratorium of river history, culture, science and management, a data archive, and the "Living WebTM," a multifaceted program of training, education and outreach projects centered on the Web and targeted at schools, colleges, libraries and their communities.
