Using Archaeological Remote Sensing To Evaluate Land Use And Constructed Space In Chaco Canyon, Jennie O. Sturm

Anthropology ETDs

Archaeological remote sensing includes a suite of non-invasive methods that can be used to study elements of the archaeological record that may not be achievable otherwise. Using primarily geophysical remote sensing, and especially ground-penetrating radar (GPR), three studies involving questions of “use” were conducted in Chaco Canyon, New Mexico. The first used GPR to study the built interior features of a single room in Pueblo Bonito to evaluate use and function of that room. Three categories of features were identified in the GPR data and confirmed with subsequent excavation. The second study used GPR to re-evaluate an enigmatic land use …

Improved Estimates Of Tributary Nitrogen Load To Casco Bay, Maine, Whitley J. Gray

Electronic Theses and Dissertations

Over the past two decades, total nitrogen (TN) concentrations have increased in Casco Bay (CBEP 2015). The sources of the increased nitrogen are poorly understood but occur with simultaneous population growth and land use changes. The total riverine nitrogen load to Casco Bay was previously estimated by Liebman and Milstead (2012) using the United States Geologic Survey’s (USGS) SPAtially Referenced Regression On Watershed attributes (SPARROW) model. The SPARROW model uses watershed characteristics, regional monitoring data and nitrogen source data to estimate nitrogen loading but was not validated using measurements of nitrogen in the Casco Bay watershed. This study attempts to …

Interpreting The Ursinus Food Forest: Visualizing, Designing, And Realizing Signage At The Whittaker Environmental Research Station (Wers), Sarah Becker

Environment and Sustainability Summer Fellows

In the fall Ursinus will begin planting the initial species of its food forest on two acres at the Whittaker Environmental Research Station (WERS), an agricultural field currently characterized by livestock forage species, just off campus. By increasing biodiversity at the site and implementing a design that mimics the structure of a healthy forest ecosystem, this food forest intends to improve the wider ecosystem’s health and resilience, while also providing the local community with a source of harvestable food and craft materials. As the system matures and becomes available to the public, interpretive materials will become imperative to ensuring visitors …

Constituent Loads And Trends In The Upper Illinois River Watershed And Upper White River Basin: 2015 October Through 2018 September, Erin E. Scott, Brian E. Haggard

Technical Reports

The Arkansas Natural Resources Commission (ANRC) identified two priority hydrologic unit code (HUC) 8 watersheds, the Upper White River Basin (UWRB; HUC 11010001) and the Upper Illinois River Watershed (UIRW; 11110103), in northwest Arkansas. Nonpoint source (NPS) pollution is a concern in these watersheds, such as excess nutrients from agriculture and sediment from changes in land uses. Several NPS pollution projects have been funded by ANRC, including streambank restoration on Sager Creek and best management practices (BMP) to control urban sediment in Fayetteville. The purpose of this project was to collect water samples at 15 sites in the UWRB and …

2002 - North Monterey County Comprehensive Water Resources Management Plan

Monterey County Water Resources Agency Water Reports

North Monterey County experiences severe water supply and quality problems including falling water levels, seawater intrusion, and nitrate contamination. The region is in a significant state of overdraft where current demands greatly exceed the annual level of recharge. Without increased supplies, dramatic changes need to occur to the North County land use pattern to reduce demand. The Comprehensive Water Resources Management Plan combines water conservation, water supply, water quality, and land use actions into comprehensive policy alternatives. It is clear, however, that capital facilities are necessary if the problem is to be solved.

The study area overlies a portion of …

Identifying The Effects Of Land Use And Policy On Disturbance Regimes In The Teanaway Community Forest, Washington, Savannah Bommarito

All Master's Theses

The historic fire regime of the forests of the Eastern Cascades, Washington, has been described as one of high-frequency, low-severity fires using fire scar analysis. Over the past few centuries, the historically open, park-like ponderosa pine-dominated stands have been significantly altered due to Euro-American land use change such as fire exclusion, grazing, mining, and logging. The eventual encroachment of shade-tolerant species has resulted in a high-density forest structure that promotes rare, but extreme fire behavior and heightened susceptibility to insect attacks. As a result, the current disturbance regime is significantly less frequent and of higher severity, posing risks to forest …
