Submersed vegetation has a major impact on characteristics of wetland systems. Percent cover of submersed vegetation data was collected bi-weekly at three treatment wetlands in central Iowa. On average 150 data points were collected in each vegetation survey. ArcGIS was used to investigate normality and stationarity. There were significant issues with normality in the dataset, leading to selection of universal Kriging method as the method for spatial interpolation.
GPS point data from vegetation surveys was interpolated to submersed vegetation cover surface. Autocorrelation analysis (Nearest Neighbor Analysis) was used to determine if the sampling method achieved significant dispersal of samples over the sampling area. Local Moran’s I and Getis-Ord G was used to analyze the patterns of vegetation growth by analyzing clustering and hotspots with results from interpolated surface rasters. Kriging interpolation was done with R, which, compared to ArcGIS, allowed for greater transparency and flexibility in scripting and fitting of the model to the dataset. ArcMap 10.4 was implemented as a visualization tool. A time series animation of interpolated surfaces shows changes in wetland vegetation from May to November. ArcScene 10.4 was used to model and animate the vegetation in the wetlands in 3D.

Improving the spatial and temporal representation of the surface water balance in streamflow forecasting models is critical for increasing the utility of water supply, flood and drought predictions. Bowman investigated the application of satellite remote sensing data in operational streamflow prediction — specifically, the consequence of the role hydrologic model structure accuracy has on streamflow simulations through input of satellite-derived evaporation data.
In her GIS application, Bowman applied several techniques to process and analyze satellite-derived and model-simulated data. Examples include automation of geoprocesses to convert time series spatial model output to files that can then be converted to raster files; raster analysis for comparison of the model simulated data to satellite data used as a validation tool; and, upscaling or downscaling, as necessary, of the satellite data to match the scale of the model simulations. Evaluation statistics of the overall streamflow simulations show mixed results with the use of the satellite-derived data. Analysis of model states indicates the water balance components progress through the model differently while simulations of streamflow discharge do not reflect this.
Nnamdi Elleh is a finalist for the position of chair of the Iowa State University Department of Landscape Architecture. He will visit campus March 26-28. His public presentation will be from 1:30 to 2:30 p.m. Monday, March 27, in room 0416 Design, followed by a discussion/question-and-answer period. Those who attend the public presentation are asked to fill out an evaluation form and submit it by 5 p.m. Wednesday, April 5, to Linda Galvin in the Administrative Services Office, 146 Design, or Jenn Wiederin in the Dean’s Office, 134 Design.
Elleh currently is a professor of architecture, history and theory in the College of Design, Architecture, Art and Planning at the University of Cincinnati. He coordinates the Master of Science and PhD programs in architecture. Research interests include modern architecture as a set of diverse, multi-centered, regional and localized experiences in different parts of the world; art, architecture, public space and politics as examined in his recent book, Architecture and Politics in Nigeria: The Study of Late-Twentieth Century Enlightenment-Inspired Modernism in Abuja, 1900-2016 (Routledge, 2016). He also studies vernacular modernism(s), architecture, tourism and environmental resources.
Elleh also is the author of African Architecture: Evolution and Transformation (McGraw Hill, 1996); Abuja, Nigeria: The Single Most Ambitious Urban Design Project of the 20th Century (Verlag Und Datenbank Fur Geisteswissenschaften, 2001); Architecture and Power in Africa (Praeger, 2002); and editor of Reading the Architecture of the Underprivileged Classes (Ashgate Publishing House, 2014). He is at work on Modern and Contemporary Architecture in Africa: Concepts, Historiography, and Theories of Sustainable Environmental Design (W.W. Norton, forthcoming).
Elleh holds a Bachelor of Arts in economics (1985) and a Master of Architecture (1994) from the University of Wisconsin-Milwaukee and a PhD in art history (20th-century architecture with a focus on Africa) (2002) from Northwestern University. He studied post-apartheid nationalist-inspired architecture in South Africa as a Fulbright Teaching-Research Scholar at the University of Cape Town in 2011-2012. He is a member of the Society of Architectural Historians, the African Studies Association and the College Art Association.
Caroline Bruzelius, founder of Wired! Lab at Duke University, will discuss how digital technologies are opening up the humanities to broader engagement with the public and revolutionizing the way scholars teach and do research. Bruzelius has been working with digital visualization technologies for art and architecture for more than 10 years and will share how they are changing how scholars model historical questions about places, buildings and change over time.
Bruzelius is the Anne M. Cogan Professor of Art, Art History and Visual Studies at Duke University and a member of the American Academy of Arts and Sciences.
Co-sponsors include the Benson Memorial Lecture in Literature, Science and the Arts; Center for Excellence in the Arts and Humanities; and Committee on Lectures (funded by the Government of the Student Body).

Carl Rogers is a finalist for the position of chair of the Iowa State University Department of Landscape Architecture. His campus interviews will be March 29-30. His public presentation will be from 1 to 2 p.m. Wednesday, March 29, in room 0416 Design, following by a discussion/question-and-answer period. Those who attend the public presentation are asked to fill out an evaluation form and submit it by 5 p.m. Wednesday, April 5, to Linda Galvin in the Administrative Services Office, 146 Design, or Jenn Wiederin in the Dean’s Office, 134 Design.
Rogers is an associate professor and interim chair of the ISU Department of Landscape Architecture. He joined the landscape architecture faculty in the ISU College of Design in 2000. He has taught courses in site engineering, site design and professional practice. Since 2011 he has directed the Community Design Lab, a collaboration between the College of Design and ISU Extension and Outreach. He served as the college’s Core Design Program director and Design Studies 102 studio coordinator in spring 2012. He has served as interim chair of the department since July 2016.
Prior to joining ISU, Rogers had been a landscape architect in training with Searle and Searle Landscape Architects in Providence, Rhode Island (1995-97), and RDG Crose Gardner Schukert (now RDG Planning and Design) in Des Moines (1997-98), and a landscape architect with Herbert Lewis Kruse Blunck Architecture, also in Des Moines (1998-2004).
Rogers holds a Bachelor of Architecture (1993) from Kansas State University and a Master of Landscape Architecture with honors (1997) from the Rhode Island School of Design. He received the Raymond G. and Lula G. Polster Teaching Award from the ISU College of Design and a Creative Achievement Award from the Association of Collegiate Schools of Architecture, both in 2008.
In April 2014, Keetra Dean Dixon packed up her happy New York City life and headed to Alaska, building a new studio practice with a remote home base. Ever since, she has been testing the claim, “I can do my job from anywhere.” Her adventuring and stubborn naivety have brought new vigor to old wisdoms as she continues to expand her category-defying practice. She’ll share how reinvention has amplified her love of developing new processes and discovering different ways to create connection through wonder.
Dixon traded in her role as an experiential design director to focus on independent practices, including lettering, sculpture and product design. Her hybrid design background continues to lead her work towards speculative terrain, leveraging emergent technologies and process-focused making.
Dixon is an ADC Young Gun and a recipient of the U.S. Presidential Award. Her client roster includes the New York Times, Nike, Volkswagen and Coach. She’s exhibited work at the Walker Art Center, the Cooper Hewitt and the Museum of Arts and Design in New York City, and her work is in the permanent design collection at the SFMOMA.
