Naturalized Daily Streamflow Reconstruction For The Upper Wabash River, Sanoar Rahman, Laura C. Bowling

Purdue GIS Day

During the 1960s, the United States Army Corps of Engineers constructed a number of dams in the Upper Wabash watershed in Indiana, primarily for flood control, hydropower and recreation. In order to investigate the impact of other environmental changes, such as changes in land management and climate on streamflow, it is necessary to reconstruct what the natural flow of the impounded river would be without the influence of the upstream reservoirs.

All projects involved mapping, mobile apps, REST services or online map-based decision support services. All students completed soem ESRI Virtual Campus training.

Indiana Freshwater Use Projection And Spatial Analysis For Renewable Water Supply, Sanoar Rahman, Laura Bowling

Purdue GIS Day

Often, when governmental and non-governmental entities attempt to make plans for future water supply and environmental flows they fall into the trap of developing strategies for specific locations rather than working together and approaching a problem from a basin or regional scale. The problem persists when lack of knowledge of local situations and confining management plans with city and county lines merge together. The purpose of this study is to project future water use and then to reveal if there is any pattern in renewable water supply in Indiana to provide a basis for policy makers and stakeholders to consider …

Applying Voronoi Tessellations As A Non-Orthogonal Grid Methodology To Inform Public-Private Mix Efforts In Nigeria: An Examination Of The Distribution Of Private Healthcare Providers In Six States And The Covariates Underlying Their Utilization, Trinadh Dontamsetti

USF Tampa Graduate Theses and Dissertations

TB care and prevention is led by the public sector, but many TB symptomatics first seek care in the private sector, highlighting the importance of engaging these facilities. This report examines basic TB epidemiology (such as the gap in case finding that could be addressed in part via private sector activities), health-seeking behaviors (HSB) and diagnostic delays, the size of the private sector, activities of professional societies, and financing. It examines the potential utility of integrating Voronoi tessellations as a GIS-based method for informing and improving Public-Private Mix (PPM) efforts throughout six states in Nigeria. Further, it explores a potential …

Selection Of A Reanalysis Meteorological Product For Use In Solar Resource Assessment, Anthony Lopez

Geography and the Environment: Graduate Student Capstones

The U.S. Department of Energy’s National Renewable Energy Laboratory and collaborators are updating the National Solar Radiation Database with the next-generation satellite-based solar resource assessment known as the Physical Solar Model (PSM). This is part of an effort to achieve NREL and DOE’s goal to make solar energy technologies cost competitive with other forms of energy in the United States. Required in this effort is the selection of an appropriate meteorological reanalysis product- that provides critical inputs for solar energy estimation. This analysis quantitatively and qualitatively assessed the spatial and temporal accuracy of three meteorological reanalysis products using ground measurements. …

An Approach To Optimal Hyperspectral And Multispectral Signature And Image Fusion For Detecting Hidden Targets On Shorelines, Charles R. Bostater

Ocean Engineering and Marine Sciences Faculty Publications

Hyperspectral and multispectral imagery of shorelines collected from airborne and shipborne platforms are used following pushbroom imagery corrections using inertial motion motions units and augmented global positioning data and Kalman filtering. Corrected radiance or reflectance images are then used to optimize synthetic high spatial resolution spectral signatures resulting from an optimized data fusion process. The process demonstrated utilizes littoral zone features from imagery acquired in the Gulf of Mexico region. Shoreline imagery along the Banana River, Florida, is presented that utilizes a technique that makes use of numerically embedded targets in both higher spatial resolution multispectral images and lower spatial …

Modis-Derived Spatiotemporal Changes Of Major Lake Surface Areas In Arid Xinjiang, China, 2000–2014, Qingting Li, Linlin Lu, Cuizhen Wang, Yingkui Li, Yue Sui, Huadong Guo

Faculty Publications

Inland water bodies, which are critical freshwater resources for arid and semi-arid areas, are very sensitive to climate change and human disturbance. In this paper, we derived a time series of major lake surface areas across Xinjiang Uygur Autonomous Region (XUAR), China, based on an eight-day MODIS time series in 500 m resolution from 2000 to 2014. A classification approach based on water index and dynamic threshold selection was first developed to accommodate varied spectral features of water pixels at different temporal steps. The overall classification accuracy for a MODIS-derived water body is 97% compared to a water body derived …

Tracking Of Karst Contamination Using Alternative Monitoring Technologies: Hidden River Cave Kentucky, Caren Raedts, Christopher Smart

Sinkhole Conference 2015

Karst groundwater contamination presents great challenges for efficient monitoring because of rapid, discrete transport and the diversity of contaminants. Here a low cost approach is described and applied to Hidden River Cave, Kentucky, where a long history of contamination has been experienced. Local knowledge was acquired through informal interviews and coupled with observations of contaminant residues, faunal distributions and fluorescence spectra in the cave. The resulting patterns were interpreted using Google Earth and Street View to identify specific contaminant sources in the affected sub-catchment of the cave. Despite success in matching contaminant sources with the contamination history and pattern, the …

‘Capitalism A Nuh’ Wi Frien’. The Formatting Of Farming Into An Asset, From Financial Speculation To International Aid, Luigi Russi, Tomaso Ferrando

Catalyst: A Social Justice Forum

This paper deciphers the formatting of farming into an asset by tracking the modalities by which financial calculation is enabled across different sites of agency.

The first focus of our analysis are commodity futures markets, which have witnessed a double spike in prices in 2008 and in 2012. In the paper, we look at these hikes as the outcome of endogenous dynamics, caused by the changing makeup of market participants after 2000, which turned futures markets into resources for hedging commodity index-linked derivative products.

We subsequently analyse the increasing reliance on financial actors placed by public development agencies that channel …

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill

Journal of Ocean and Coastal Economics

In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …
