NITY SEMINAR SERIES
           Presentation Title and Description
           Monitoring and Modeling of Circulation in Lakes
           The Indiana Water Monitoring Inventory: A tool for locating water monitoring information in Indiana
           Ecology and Evolution of An Aquatic Ecologist - Take a Swim on the Wild Side
           Water Availability in a Changing Environment

            What's in the Pool? Swimming Pool Chemistry and Human Health Implications
            Reactions between free chlorine and human-introduced chemicals in swimming pools lead to formation of a
            wide range of disinfection by-products (DBPs). Opportunities for human exposure to swimming pool DBPs are
            extensive, and several adverse human health effects are known or suspected to be linked to these compounds.
            Included in this presentation will be a discussion of the nature of the DBPs that are common to pools,
            representative DBP concentrations, the analytical methods used for swimming pool water characterization, and
            the need to develop a general-use analytical facility for the water community.

            Agricultural Drainage and Soil and Water Quality –
            Agricultural drainage provides many benefits for water quality but also presents some challenges. I’ll discuss
            research on reducing chemical loads to drains and improving soil quality, and will ask some questions about
            scaling up to optimize practices on a watershed basis.

            A Simple Case of Scour? Scour is a fundamental sediment transport phenomenon with implications in hydraulic
            engineering, fluvial geomorphology, and possibly even the study of aquatic habitat. We consider an idealized
            case of scour that is primarily two-dimensional, and discuss experimental results that raises interesting
            questions regarding the nature of equilibrium scour, the mechanisms, and the time scales involved.
            Environmental Fate and Transport of Chemicals: Fullerene Photochemistry, PAHs in River Sediments, and
            Nutrients in Agricultural Ditches
            To study these old and new environmental issues, we must take advantage of old and new tools to discover
            dominate environmental processes.


            Backcasting and Forecasting Land Use-Hydrologic Interactions: Importance of Legacies, Temporal Profiles and
            Planning Scenarios for Watershed Management - Humans have altered landscapes through land use change
            significantly over the last century. These changes have had perverse impacts on the hydrologic cycle and water
            biogeochemistry. Through the use of backcasting and forecasting land change models, I illustrate several
            important reasons how past land uses impact current land use planning considerations. The concepts of land
            use legacies, temporal profiles and chronologies, and future ecological-economic planning scenarios will be
            briefly summarized in this presentation.

            Lakes and wetlands in arctic environments - Lakes and wetlands are prevalent in Arctic environments, due to a
            history of glaciations and the presence of permafrost. This surface storage provides a poorly quantified control
            on the discharge into the Arctic Ocean. In addition, interactions between the soil thermal and moisture regimes
            lead to disparate observations of changes in lake and wetland extent in the face of recent climatic warming at
            high latitudes. I will describe on-going model development aimed at helping to improve our understanding of
            this sensitive region.
A chicken-and-egg conundrum: Energy or water? - Producing energy demands water, and water treatment
and distribution consume energy. How can this interdependency be quantified, and could it be used to diminish
overall environmental impacts of utilities?


Scaling-up to the population level: Linking empirical and modeling studies of fish - A wide range of studies
demonstrate how fish respond individually (and molecularly) to a seemingly infinite suite of
physical/chemical/biological factors. However, since fish stocks are generally managed at the population or
community level, there is a need to scale up such lower level understanding to population-level consequences.
I will present some examples of inter-disciplinary studies whereby we have integrated field/laboratory
approaches with modeling analyses to explore population and food-web processes.
Social Dimensions of Watershed Management - In this talk, I will present an overview of a regional framework
for measuring social indicators. I will discuss how this framework can help improve watershed planning and
implementation.

Pedostructure: Prospects for Multi-Scale Hydrologic Modeling - A fundamental problem confronting the
hydrologic systems is the lack of interdisciplinary linkages to the Pedology of these systems that controls the
hydrologic processes. Soil structure contains a hierarchy of organization at several different scales that also
varies spatially, to constitute what is known as the soil cover. Based on methodology involving soil mapping,
characterization and modeling approaches this research explores the application of systems theory to pedology
and soil physics; and characterization and modeling of the hydrostructural soil organization to provide a
platform for connecting the hydrologic scales.


Water Infrastructure Systems: Changing the Paradigm in Indiana - Recent reports from the National Research
Council and the National Academy of Engineering both list water infrastructure systems as critical challenges to
be addressed in the future. Managing future water resources and developing sustainable solutions for water
infrastructure problems will require new approaches. The Purdue Water Community can and should have a
leadership role in setting a new direction that will have great environmental and economic impact. Future
water infrastructure challenges present the Purdue Water Community with opportunities around which
research themes and identity can emerge. Many of the barriers to implementing alternative water
management strategies are not technical limitations but rather “business as usual is easier” economic, social,
regulatory and political attitudes. The NRC asserts that using “the same processes, practices, technologies, and
materials that were developed in the 20th century and will likely yield the same results” which are
underperforming, short lived, more expensive systems that are more vulnerable to failure. Some examples of
problems that have been solved with traditional methods will be discussed, as well as alternative solutions that
could have been considered.

Improving Water Quality in Drained Agricultural Watersheds: What Has the Most Impact? Our
understanding of nutrient loading from drained agricultural land continues to increase, but nutrient loads in
Indiana’s streams are not generally decreasing, despite millions of dollars spent on conservation practices. I do
not propose to answer the question posed in the title of this seminar, but will present watershed modeling,
monitoring, and education activities I am involved in that might contribute towards solutions, and hopefully
generate lively discussion about future directions.
Biodiversity and Environmental Studies of Aquatic Vertebrates and Water-Related Initiatives in the Center for
the Environment - I’ll talk about my use of aquatic vertebrates in ecotoxicology studies in Azerbaijan,
population genetic studies of Steller sea lions and bowhead whales, and ongoing C4E initiatives that might
relate to the water community.
Water, Wildlife, and Development: Panama Under Transition - I plan to talk about water resource issues
relative to economic development and the canal expansion project. I’ll also talk about wildlife rescue efforts in
the canal zone plus plans to develop an eco-tourism industry.
Water isotopes: Research and opportunities at Purdue - I will briefly introduce a range of ways that the water
isotopes (2H/1H and 18O/16O) are being used in the Isotope Ratio Hydrology and Ecology group and
collaborative projects at Purdue. These include studies to trace fluxes of water between the land surface and
atmosphere, natural fluxes and human diversion of water across the land surface, reconstruction of
paleoclimate from sedimentary archives preserving water isotope proxy records, and ecological studies
involving assimilation of water isotope signatures by plants and animals. I will describe existing analytical
capabilities and future development goals of the Purdue Stable Isotope Recharge Center (PSIRC), an open
resource for the campus research community.
Hormones and Hormone-mimics in the Environment: The New Generation of Gender-Bender Fish and Wildlife
- Hormones play complex roles in living organisms, stimulating and inhibiting various cellular functions. Over
the past decade, scientists have discovered several dozen environmental pollutants that can act as hormones
and thus are capable of disrupting normal development. I will present work on estrogen and androgen mimics
and how exposure to minute concentrations of these compounds can lead to changes in sexual development
and reproductive output.
Water Research Results for Policy Makers – Otto Doering will talk about his involvement in national
assessments related to water quality and the trials and tribulations of such efforts.
Flood Modeling and Mapping: History and Research Opportunities - In this brief talk, I will discuss the state-of-
the-art related to flood modeling and mapping at the national level, and describe some of our recent work
related to this topic.
Pesticides and Water Quality: Products of Past and Present Regulatory Paradigms and Collaborative
Opportunities

Quantifying soil-landscape relationships to create functional maps - The soil heterogeneity has been
represented by soil series with broad ranges of soil property values between and within map units with no
representation of the continuum of soil property values. Currently with high quality DEM’s, Online Soil Survey
(SSURGO), geographical information systems (GIS) and powerful geo-referencing tools, the specific geo-
referenced spatial location can be used to understand soils. Additionally, recent advances in terrain-based
digital soil mapping allow us to take a new approach of mapping soils based on their functional similarities
rather than the taxonomic heterogeneities. Discrete soil property values associated with each soil polygon are
weighted by their "influence" based on their fuzzy membership values to generate continuous functional soil
property maps rather than discrete taxonomic soil map units. This presentation will provide examples of
methods used to create functional maps and examples that apply to watershed research.
Visualizing Soil Landscapes - Many of the concepts that soil science students must master are inherently
spatial. Although we implicitly acknowledge the existence of spatial patterns in our courses, our ability to
explicitly make these spatial patterns clear to our students has been limited. I will describe how we are teaching
students complex soil geomorphological concepts in the field using geographic information system (GIS)
software running on rugged tablet PCs equipped with GPS receivers. For the classroom, we are developing a
web-based application based on Google Earth. We use a high resolution, 5 meter Digital Elevation Model (DEM)
of the state as our base map, and then overlay various thematic maps derived from the detailed, second order
soil survey. Soil parent material, soil drainage class, loess depth, and many other features can be displayed at
resolutions from 1:3,000,000 to 1:2,000. Although our focus has been on teaching and learning, the data sets
we have developed and the issues we have encountered have broader applicatons to the water community at
Purdue.
