This second of three parts of the history of the St Anthony Falls Laboratory (SAFL) at the University of Minnesota documents environmental research. From its beginning in 1938, SAFL has been an interdisciplinary science and engineering research and educational facility with a strong grounding in fluid mechanics. Starting in the 1970s, SAFL’s areas of research expanded to include the interconnection of fluid flow processes with the chemistry and biology of aquatic environments.
Environmental research at SAFL began with its early interest in sediment-related processes. Since that time, cutting edge models of lake and stream water quality have been developed by SAFL researchers. The influence of fluid flow on the growth of microorganisms has also been extensively studied. Geo-physical processes became a centerpiece of SAFL research with the National Center for Earth- surface Dynamics (NCED), which had a home at SAFL from 2002 to 2012. Fluid flows in the human body such as with blood and air have been studied as well. Environmental studies have used laboratory- and field-scale experimentation, deterministic and stochastic analysis, and analogue (model) or numerical simulations. Sophisticated experimental facilities and data acquisition and simulation tools have been developed by SAFL’s researchers.
Examples of environmental research and design studies conducted at SAFL will be presented in eight major areas: (1) water-sediment interactions in the geo-physical environment; (2) protection of fish and fish habitat; (3) pollutant transport from effluents into the environment; (4) water quality dynamics and management in lakes and reservoirs; (5) eco-fluid/micro-organism mechanics and ecosystems; (6) nutrient chemistry and transport in the environment; (7) storm water runoff and water quality improvement in the urban environment; (8) global climate change effects on water resources and fish habitat availability.
Specific historical examples will showcase the evolution of SAFL capabilities and the significance of the associated research.
