Research Interests:

This working group’s primary thrust area is reservoir sedimentation. There are more than 130,000 reservoirs in Kansas greater than one-quarter of an acre in size. They are gradually filling up with sediment, some at much faster rates than others; and several major reservoirs are filling up at alarmingly high rates. Sediment buildup in reservoirs degrades water quality, commonly manifested in more frequent algal blooms, taste-and-odor episodes, and fish kills, and diminishes their capacity to serve their intended purposes, such as flood control, water supply, recreation, and fish and wildlife habitat.

The group seeks to address this problem, in concert with other individuals and organizations, by:
1) gaining greater understanding the actual sources of the sediment entering Kansas reservoirs (e.g., field runoff versus streambank erosion) and evaluating the effectiveness (and cost-effectiveness) of measures to prevent sediment from entering reservoirs; 2) examining the potential for reservoirs to be redesigned so they either retain less sediment or are less adversely impacted by sediment accumulation; 3) evaluating alternative dredging equipment and techniques, alternatives to dredging, and novel ways to cost-effectively utilize dredge spoils; 4) assessing the ecological impacts of sediment on reservoirs, and on streams upstream and downstream from reservoirs, and ways to minimize such impacts; 5) characterizing the changes that occur in the chemical and biological functioning of smaller reservoirs (e.g., farm ponds) as they age, and identifying the ecological and water quality implications of these changes; 6) gathering more data to characterize the condition of the overwhelming majority of Kansas reservoirs for which little or no data are currently available; 7) estimating the financial costs associated with current and alternative reservoir management strategies over the next 50 to 75 years, including the increased drinking water treatment costs incurred by municipalities as the quality of their source water deteriorates; and 8) determining how reservoir sedimentation, dredging, and disposition of dredge spoils affects mosquito populations and toxic algae, as related to public health.

This group began meeting in November, 2013. To date, the group has focused primarily on reservoir sedimentation, but one subgroup is currently considering applying for a grant to examine the ecological impacts of manufactured chemicals, another subgroup is evaluating potential sources of funding for novel techniques to assess watershed morphology, and the group as a whole is reviewing potential funding sources for opportunities to collaborate on other research topics of interest to some or all members of the group.

Other research topics of interest to various members of the group, which may eventually morph into defined thrust areas, include:
1) the impacts of nested impoundments and reservoirs within watersheds, under current and estimated climate conditions, on creation of artificial flow regimes, retention of sediment and organic matter, loss of floodplain/river connectivity, and emigration and immigration of species; 2) algal toxin occurrence, effects, and control; 3) drinking water treatment to control naturally occurring and synthetic chemical contaminants; 4) the impacts of nutrients, pharmaceuticals, and other contaminants on receiving streams, and treatment processes for removing these and other constituents from wastewater and stormwater; 5) water quality monitoring, particularly with respect to pathogens and identifying their sources using microbial source tracking techniques; 6) water quality modeling of agricultural runoff; 7) using statistical methods and GIS to analyze and improve hydrologic design methods; 8) applications of radar-based rainfall estimates in hydrologic modeling; and 9) developing sound engineering procedures to modify streams altered by human activity to better mimic natural channels.
