Mapping Lake Michigan Fish Catch Data, Jacob Wodd, Jarrod Doucette, Tomas O. Höök

Purdue GIS Day

The only Great Lake completely contained in the U.S., Lake Michigan offers an abundance of recreational fishing. This project takes 20 years’ worth of salmonid fish catch data, and uses GIS to organize and visually represent the data in a way that is meaningful and helpful to local fisherman and researchers. Species represented included Brown Trout, Lake Trout, Rainbow Trout, Chinook Salmon, and Coho Salmon. The species are organized by both decadal and yearly spans, as well as catch per trip, catch per angler hour, and total catches. These data are the foundation for a web based app that allows …

Functional Approach To Simulating Short Rotation Woody Crops In Process Based Models, Tian Guo, Bernard Engel

Purdue GIS Day

Short rotation woody crops (SRWC) such as hybrid poplar have great potential as a biofuel feedstock. Biomass yields and yield stability at potential sites are important considerations when such SRWC is widely planted. To simulate poplar growth accurately, the functional components and parameters of hybrid poplar Tristis #1 (Populus balsamifera L. × P.tristis Fisch) were determined, and related algorithms improved in ALMANAC and SWAT based on improved simulation of leaf area and plant biomass as well as biomass partitioning. The improved tree growth simulation was applied to hybrid poplar plots in Wisconsin, and the modeled biomass yield, and LAI were …

Water Resources And The Historic Wells Of Barbuda: Tradition, Heritage And Hope For A Sustainable Future, Rebecca Boger, Sophia Perdikaris, Amy E. Potter, John Mussington

Earth, Environment & Sustainability: Faculty Publications

The island of Barbuda has a relatively unique history, land tenure and geography. Unlike its Caribbean counterparts, the island is not suited to large-scale agriculture due to its arid climate and relatively thin soils. Instead, the enslaved and eventually free people of Barbuda developed a complex herding ecology centered on common land ownership. As a result, carefully designed historic wells are strategically located around the island. With the challenges brought about by climate change, an interdisciplinary, international team led by the Barbuda Research Complex is investigating the state of existing water and food resources and examining how the availability and …

China's Nine-Dashed Map: Maritime Source Of Geopolitical Tension, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

The South China Sea (SCS) is becoming an increasingly contentious source of geopolitical tension due to its significance as an international trade route, possessor of potentially significant oil and natural gas resources, China’s increasing diplomatic and military assertiveness, and the U.S.’ recent and ongoing Pacific Pivot strategy. Countries as varied as China, Taiwan, the Philippines, Indonesia and other adjacent countries have claims on this region’s islands and natural resources. China has been particularly assertive in asserting its SCS claims by creating a nine-dash line map claiming to give it de facto maritime control over this entire region without regard to …

An Investigation Of Methodologies For Determining Walkability And Its Association With Socio-Demographics: An Application To The Tampa - St. Petersburg Urbanized Area, Oana A. Mckinney

USF Tampa Graduate Theses and Dissertations

Walkability research has broadened in the past few years, being performed by researchers in different fields such as urban planning, public health, and transportation planning. Definitions of walkability and methods of operationalizing the concept vary widely. Since the results of studies that incorporate walkability may well have policy implications, it is important to consider the potential impacts of different definitions and methods of measurement.

This thesis investigates to what extent walkability indices may differ when either the composition of the indices is changed or when different quantitative methods of standardization are used to summarize their component measures. The association of …

Assessing The Impacts Of Climate And Land Use And Land Cover Change On The Freshwater Availability In The Brahmaputra River Basin, M. S. Pervez, G. M. Henebry

Natural Resource Management Faculty Publications

Study Region: Brahmaputra River basin in South Asia.

Study Focus: The Soil and Water Assessment Tool was used to evaluate sensitivities and patterns in freshwater availability due to projected climate and land use changes in the Brahmaputra basin. The daily observed discharge at Bahadurabad station in Bangladesh was used to calibrate and validate the model and analyze uncertainties with a sequential uncertainty fitting algorithm. The sensitivities and impacts of projected climate and land use changes on basin hydrological components were simulated for the A1B and A2 scenarios and analyzed relative to a baseline scenario of 1988–2004.

New hydrological insights for …

Lake Flooding And Synoptic Weather-Type Frequency At Devils Lake, North Dakota, Usa, Between 1965 And 2010, Paul E. Todhunter, Emily A. Knish

Geography & Geographic Information Science Faculty Publications

Since the spring of 1993, the water surface elevation at Devils Lake, a terminal lake in eastern North Dakota, USA, has risen by 8.8 m, producing more than 1 billion USD in direct flood damages. We examine the relationship between weather-type frequencies at Bismarck, North Dakota, and lake volume changes from 1965 to 2010 using the Spatial Synoptic Classification (SSC) system. First, we find statistically significant changes in the frequency of selected weather types over both annual and seasonal time periods. This indicates a trend toward in - creased advection of more humid weather types that is consistent with the …

Mapping Licit And Illicit Mining Activity In The Madre De Dios Region Of Peru, Arthur Elmes, Josué Gabriel Yarlequé Ipanaqué, John Rogan, Nicholas Cuba, Anthony J. Bebbington

Geography

Since the early 2000s, the Madre de Dios Region of southern Peru has experienced rapid expansion of both licit and illicit mining activities, in the form of artisanal and small-scale mining (ASM). ASM typically takes place in remote, inaccessible locations and is therefore difficult to monitor in situ. This paper explores the utility of Landsat-5 imagery via decision tree classification to determine ASM locations in Madre de Dios. Spectral mixture analysis was used to unmix Landsat imagery, using WorldView and QuickBird l imagery to aid spectral endmember selection and validate AMS maps. The ASM maps had an overall area-weighted accuracy …

Sustainability Planning, Environmental Justice And Climate Change: Applications Of The Long Island Markal Model, David S. Friedman, Yehuda Klein, Jose Pillich, Michael T. Sullivan

Suburban Sustainability

As pointed out by many authors, sustainability is often vague and amorphous (See, for example, Dovers, 1989; Faber, et al, 2005; Glavič, et al. 2007). There is a clear need to make analytical and data-driven analyses of established and or proposed plans. MARKAL (MARKet ALlocation model) is an analytical tool that can be used characterize the impacts of sustainability plans at multiple spatial scales: global, national, regional, and local. In this study we apply the Long Island MARKAL model to answer three interrelated issues: 1, the development and incremental improvement of local and regional sustainability plans; 2, the impact of …

Hidden In Plain Sight: Exploring The Vulnerabilities Of Street-Working Boys In Se Asia, Jarrett Davis, Glenn Miles

Annual Interdisciplinary Conference on Human Trafficking: 6th (2014)

The sexual exploitation of men and boys is often little understood and commonly goes ignored. Internationally, it is said that 1 in 6 boys are sexually abused before reaching adulthood and in some nations the exploitation and abuse of boys far outweighs that of girls. Social and cultural norms often assume men and boys to be inherently strong and/or invulnerable to sexual exploitation; however, research in this area continues to show these assumptions to be false. Because of this lack of awareness, the efforts of the organizations and individuals who work to provide for the needs of male victims are …
