John Little, PhD. Professor of Civil Engineering Virginia Polytechnic Institute, Blacksburg, VA email: jcl@vt.edu
Dr. John Little and Dan McGinnis (doctoral candidate) at VPI assist the aeration team in the modeling of aeration systems and linking their performance to water quality improvements in reservoirs, tailwaters, and rivers. The following aeration systems have been modeled by the aeration team and these partners: the porous hose line diffuser, bubble plume upwelling, the Speece cone, a side-stream supersaturation system, and a Kortman aerator.
Dan McGinnis Bubble Plume Technical Specialist EAWAG, Switzerland email: dan.mcginnis@eawag.ch
Mr. McGinnis (with Dr. John Little) has developed an aeration model that can be applied to any aeration method, and both work with members of the aeration team to incorporate the results into far-field reservoir water quality models and draft tube venting models.

Jon Knight, PhD. Limnologist Charlotte, NC email: joncknight@adelphia.net
Professional
experience has covered a broad range of limnology, with emphasis
on physical (heat and mass transfer) and chemical (dissolved oxygen,
carbon dioxide, and nutrient) processes as related to plankton dynamics,
plankton bioenergetics, and suspended solids. Professional goal
is to establish valid limnological and ecological models for reservoirs
and associated downstream releases for use in establishing reservoir
management strategies. Current research activities center on the
role of water use patterns (intake and discharge structures), meteorological,
and land use (erosion and runoff), as influencing the physical and
associated chemical dynamics of reservoirs and rivers.
Perry Johnson Environmental Hydraulics Denver, CO email: mkplj@aol.com
Mr. Johnson is an environmental hydraulics engineer who has extensive experience in using selective withdrawal approaches for improving water quality in the discharges from hydropower projects. He worked for the Bureau of Reclamation at the Federal Laboratory in Denver and developed various solutions for water quality problems at BOR projects. He works with members of the aeration team to evaluate methods such as submerged curtains and plates on the intakes or trash racks to improve water quality in tailwaters.
