Inland Lakes Project
|Management of lakes is somewhat diffuse with authority organized around various levels including federal, state, water conservation districts, lake associations, and local land owners. While management approaches and goals vary among these different levels, there is a shared desire to sufficiently manage lakes and to predict the response of lake attributes to changing internal and external drivers.
The goal of our research efforts is to improve the ability of managers and stakeholders to anticipate how potential management decisions and natural dynamics interactively influence physical, chemical and biological characteristics of lakes. We hope to develop understanding and specific tools which will ultimately facilitate improved management of not only Indiana's glacial lakes, but also lakes and reservoirs in other regions.
Key aspects of our research approach are
1) development of methodologies and understanding with a focus on relevant endpoints for resource managers,
2) integration of information and quantitative model syntheses across a hierarchy of spatial and temporal scales, and
3) explicit consideration across the cause-and-effect chain: from drivers (land-use and climate) to management relevant endpoints (water quality effects and fisheries production).
Fate of Hormones in Tile-drained Fields and Impact to Aquatic Organisms Under Different Animal Waste Land-Application Practices
|This project is investigating the persistence and level of hormones entering the environment, specifically observing waterways next to agricultural land where animal manure from confined feeding operations is applied. The thrust of the research is to document hormone loads leaching from agricultural fields with tile drains that have animal manures applied, and to elucidate the mixing synergy of a suite of natural and synthetic hormones and their impact on water quality and aquatic organisms. The project is based at the Purdue Animal Science farms and utilizes the Purdue Water Quality Field Station.|
Mapping the Condition of Diporeia: Insights to Mechanisms of Declines
The holo-arctic amphipod, Diporeia spp., historically constituted a large component of benthic invertebrate communities throughout the Great Lakes region. However, since the early 1990's, this species-group has experienced a precipitous decline in abundance in the Great Lakes.
2)in the laboratory, use metabolomic techniques to characterize the metabolite profiles expressed by individual Diporeia when exposed to various environmental stressors; and
|The core tenet of the Isoscape Modeling, Analysis and Prediction (IsoMAP) project, a NSF-funded partnership between researchers at Purdue and Texas A&M University, is that spatial analysis can transform and integrate large datasets in ways that enable specialist analysis and non-specialist access. This data is commonly stored and distributed through decentralized databases, and provided in formats that create a 'barrier to entry' for potential users.
Within the IsoMAP project, we are developing a web-based geospatial modeling environment within which diverse datasets can be seamlessly combined and analyzed to produce maps of environmental chemistry over a range of systems and scales. These maps constitute a powerful and accessible common format for data access and interrogation, facilitating data exploration and hypothesis testing by specialists and non-specialists alike. As the nation moves forward with ambitious plans to monitor its environment and ecology, web-based cyberinfrastructure such as IsoMAP will increase the impact and widespread use of the large data sets resulting from these programs.
Soil Water Interaction Agro-Environment Modeling Project
|The Soil-Water Interaction Agro-Environment Modelling Project proposes revisiting existing soil maps (delinearization and characterization of primary soil map units) using the systems approach with addition of measured pedostructure thermodynamic parameters of representative soil mapping units that ensures the physical link with agronomic, biologic and geochemical models, and also, the physical link with geophysical mapping and remote sensing survey. This work of revisiting existing soil maps and database (multiscale) into the pedostructure/pedoclimate paradigm, will allow us to develop a soil information system as a platform for cropping system modeling.|
The Water Erosion Prediction Project (WEPP)
|WEPP is a national project, begun in 1985, focused on creation of next generation erosion prediction tools. Major model development was completed in 1995, but substantial work on interface and database development, model applications, user support, and software maintenance and updates continues. WEPP is a physically-based computer simulation model, for prediction of runoff, soil loss, and sediment yield from hillslope profiles and small watersheds up to about 260 ha in size. WEPP is maintained by the USDA-ARS National Soil Erosion Research Laboratory (NSERL), on the campus of Purdue University.|
Additional multi-collaborator projects will be listed in the near future.
