The Iowa State Water Resources Research Institute (ISWRRI) is a multi-campus, interdisciplinary research and training program focusing on major water resource problems facing Iowa and the nation. ISWRRI's roles are to assist in the solution of water problems by providing timely research on critical water issues and to educate engineers and scientists who are needed by the private and public sectors involved in water resources planning, development, and management.

ISWRRI cooperates in research conducted at all the Iowa Regents Universities. This inter-institutional linkage makes the ISWRRI research program much more effective in bringing together interdisciplinary research teams from all the Iowa universities to focus on critical needs.
