River Management Decision Support System (RIMDESS)
Since 1991, RTI has been involved in the development of decision support systems (DSS) for water quality management in Central and Eastern Europe, Central Asia, and, now, the United States. RTI's River Management Decision Support System (RIMDESS) is an approach to managing water quality that centers on a computerized data integration and modeling tool.
RIMDESS is a PC-based system that integrates databases on instream water quality, dischargers, pollutant loads, regulatory standards, hydrologic structure, and treatment costs, and an array of programs for analyzing these data. RIMDESS supports informed decision-making regarding the control of emissions in a watershed. Most water resources agencies in the U.S. and abroad have scattered databases and models that do not talk with each other -- they lack linkages and tools to evaluate the complex interactions in a river basin . RIMDESS allows users to evaluate the water quality and economic impacts of management options for controlling emissions from industrial and municipal point sources and nonpoint source runoff.
RIMDESS represents a collaborative effort among the staff of RTI's Centers for Environmental Analysis and International Development. Tim Bondelid led the project in the Danube and the technical work and training in the Aral Sea Region; Gene Brantley led the institutional work in the Aral Sea Region and Peter Iliev developed databases, adapted models, and provided training in that Region. The work was sponsored by the U.S. Agency for International Development's Environmental Policy and Technology Project under contract to CH2MHill.
