Understanding species-habitat relationships is vital to successful conservation, but the tools used to communicate species-habitat relationships are often poorly suited to the information needs of conservation practitioners. Here we present a novel method for translating a statistical species-habitat model, a regression analysis relating ring-necked pheasant abundance to landcover, into an interactive online tool. The Pheasant Habitat Simulator combines the analytical power of the R programming environment with the user-friendly Shiny web interface to create an online platform in which wildlife professionals can explore the effects of variation in local landcover on relative pheasant habitat suitability within spatial scales relevant to …
Improving The Accuracy Of Cosmic-Ray Neutron Probe Estimate Of Soil Water Content Using Multiple Detectors And Remote Sensing Estimates Of Vegetation, Xiaochen Dong
School of Natural Resources: Dissertations, Theses, and Student Research
The recently developed Cosmic-ray Neutron Probe (CRNP) for estimating soil water content (SWC) fills a critical measurement gap between point scale methods and large scale measurements collected from remote sensing. CRNP works by measuring the change in low-energy neutron intensity over time. However, the accuracy of CRNP to measure SWC is well known to be affected by other hydrogen sources (e.g. soil organic content, atmospheric water vapor, vegetation and surface water). This study focuses on the influence of rapidly growing vegetation in agricultural fields on the accuracy of the CRNP method. Here we use data from three long-term CRNP study …
Water Chemistry Dynamics In Four Vernal Pools In Maine, Usa, Lydia H. Kifner
Water Chemistry Dynamics In Four Vernal Pools In Maine, Usa, Lydia H. Kifner
Electronic Theses and Dissertations
Vernal pools are small seasonal wetlands that are a common landscape feature that contribute to biodiversity in northeastern North American forests. However, even basic information about their biogeochemical functions, such as carbon cycling, is limited. Dissolved gas concentrations (CH4, CO2) and other water chemistry parameters were monitored weekly at the bottom and surface of four vernal pools in central and eastern Maine, USA, from April to August 2016. The vernal pools were supersaturated with respect to CH4 and CO2 at all sampling dates and locations. Concentrations of dissolved CH4 and CO2 ranged …
Changing Tides In Water Management: Policy Options To Encourage Greater Recycling Of Fracking Wastewater, Romany M. Webb
Changing Tides In Water Management: Policy Options To Encourage Greater Recycling Of Fracking Wastewater, Romany M. Webb
William & Mary Environmental Law and Policy Review
The U.S. has recently experienced a domestic energy renaissance, made possible by technological advances, enabling the development of unconventional oil and gas resources. Vital to this development is hydraulic fracturing (“fracking”), whereby fluid is injected underground at high pressure to fracture the rock, thereby enabling the flow of oil and gas. Fracking has recently faced growing opposition with many concerned about its environmental impacts, particularly its potential to adversely affect water resources, because fracking uses vast amounts of fresh water that ends up as contaminated wastewater. Most of this wastewater is disposed of through underground injection, resulting in its permanent …
A Fix For A Thirsty World - Making Direct And Indirect Reuse Legally Possible, Heather Payne
A Fix For A Thirsty World - Making Direct And Indirect Reuse Legally Possible, Heather Payne
William & Mary Environmental Law and Policy Review
Reliably providing safe drinking water to the public is an essential function of state and local governments. Across the United States, government officials and public water system managers are exploring mechanisms for ensuring water security. One method for increasing public drinking water security that has garnered the attention of water officials and the public is returning treated wastewater to the drinking water supply. However, in the absence of federal regulations on water reuse, states need guidance to develop the statutory framework necessary to make potable reuse legal. This Article details the processes of direct and indirect potable reuse and reviews …

Target 6.4 of the recently adopted Sustainable Development Goals (SDGs) dealswith the reduction ofwater scarcity. To monitor progress towards this target, two indicators are used: Indicator 6.4.1 measuring water use efficiency and 6.4.2 measuring the level of water stress (WS). This paper aims to identify whether the currently proposed indicator 6.4.2 considers the different elements that need to be accounted for in a WS indicator.WS indicators compare water use with water availability.We identify seven essential elements: 1) both gross and net water abstraction (or withdrawal) provide important information to understand WS; 2) WS indicators need to incorporate environmental flow requirements …

Improving The Accuracy For The Long-Term Hydrologic Impact Assessment (L-Thia) Model, Anqi Zhang, Lawrence Theller, Bernard A. Engel
The Summer Undergraduate Research Fellowship (SURF) Symposium
Urbanization increases runoff by changing land use types from less impervious to impervious covers. Improving the accuracy of a runoff assessment model, the Long-Term Hydrologic Impact Assessment (L-THIA) Model, can help us to better evaluate the potential uses of Low Impact Development (LID) practices aimed at reducing runoff, as well as to identify appropriate runoff and water quality mitigation methods. Several versions of the model have been built over time, and inconsistencies have been introduced between the models. To improve the accuracy and consistency of the model, the equations and parameters (primarily curve numbers in the case of this model) …
Understanding Cigarette Butt Littering Behavior On Public Beaches: A Case Study Of Jekyll Island, Georgia, Maranda R. Miller
Understanding Cigarette Butt Littering Behavior On Public Beaches: A Case Study Of Jekyll Island, Georgia, Maranda R. Miller
School of Natural Resources: Dissertations, Theses, and Student Research
The world’s natural environment is degrading, and human behavior is a leading cause. Therefore, in order to address environmental problems it is important to understand the factors driving environmentally degrading behaviors and subsequently design behavioral interventions to alter undesirable behaviors.
One environmental issue of particular concern is toxins leeching from trash. Specifically, cigarette butts are of concern due to their prevalence in the environment. Cigarette butt discarding behavior is affected by personal attributes, but data regarding which personal attributes and how these affect discarding behavior is lacking. This thesis seeks to understand cigarette butt disposal on public beaches by exploring …
Soil Ecosystem Service Tradeoffs And Social-Ecological Resilience In The North Central Great Plains, Hannah E. Birge
Soil Ecosystem Service Tradeoffs And Social-Ecological Resilience In The North Central Great Plains, Hannah E. Birge
School of Natural Resources: Dissertations, Theses, and Student Research
Humans seek to improve their wellbeing by altering ecological processes to maximize the output of specific ecosystem services, which often leave the system vulnerable to unintended and undesirable side effects. Ecosystem services emerge from complex interactions among ecological structures and processes occurring at multiple scales. The degree to which an ecosystem maintains a predictable range of structures and processes in the face of disturbance can be described as its resilience. The 1930s Dust Bowl of the North American Great Plains is an example of a system reconfiguration and loss of resilience that was ultimately driven by human optimization for a …
Loss Of Buffer Value Due To Aquifer Depletion: The Case Of High Plains Aquifer, Mani Rouhi Rad, Timothy Foster, Nicholas Brozovic
Loss Of Buffer Value Due To Aquifer Depletion: The Case Of High Plains Aquifer, Mani Rouhi Rad, Timothy Foster, Nicholas Brozovic
Daugherty Water for Food Global Institute: Faculty Publications
Existing literature in economics and engineering do not realistically capture the effects of aquifer depletion on loss of profits from agricultural production. While the former literature ignores the physical characteristics of aquifer and the relationship between aquifer levels and groundwater availability, the latter strand of literature does not consider farmers' decisionmaking as a result of aquifer depletion. Misspecification of these relationships and their effect on irrigation decisions can result in misunderstanding the consequences of aquifer depletion and may provide ineffective policies. This paper provides a framework to study the effects of aquifer depletion on the profit of agricultural production. We …
Using Mountain Snowpack To Predict Summer Water Availability In Semiarid Mountain Watersheds, Rebecca Dawn Garst
Using Mountain Snowpack To Predict Summer Water Availability In Semiarid Mountain Watersheds, Rebecca Dawn Garst
Boise State University Theses and Dissertations
In the mountainous landscapes of the western United States, water resources are dominated by snowpack. As temperatures rise in spring and summer, the melting snow produces an increase in river flow levels. Reservoirs are used during this increase to retain surplus water, which is released to supplement growing season water supply once the peak flows decrease to below water demands. Once there is no longer surplus natural flow of water, the water accounting changes – referred to as the day of allocation (DOA), and water previously retained within the reservoir is used to supplement the lower flow levels. The amount …

Nudging Neighbors: Analyzing Peer Effects Of The Lakesmart Program In The Belgrade Lakes, George A. Voigt
Journal of Environmental and Resource Economics at Colby
Peer effects are an increasingly studied field in economics, and can have large impacts at a local level. In this research we seek to identify whether there is an impact of early adopters on their neighbors to become adopters. The scope for this study is the LakeSmart program that operate in Maine. Specifically we are focusing on the Belgrade lakes, and analyzing data from 2005 to present in addition with a survey of demographic characteristics conducted in 2011. Results suggest that the impact of a neighbor on the likelihood of a household to be LakeSmart certified is statistically significant and …
Water Restrictions And Water Use: An Analysis Of Water Restriction Effects In Norfolk County, Rebecca L. Robinson, Ashley Conley
Water Restrictions And Water Use: An Analysis Of Water Restriction Effects In Norfolk County, Rebecca L. Robinson, Ashley Conley
Journal of Environmental and Resource Economics at Colby
This paper aims to determine what effect water restrictions in Norfolk County, Massachusetts have on residential water usage. Using data from the Massachusetts Department of Environmental Protection, this paper analyzes subsequent municipal water usage within and across towns after water restrictions, both mandatory and voluntary, are implemented. Accounting for town fixed effects, the results indicate that for some towns, water restrictions do in fact have a significant impact on decreasing water usage.
The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney
The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney
Journal of Environmental and Resource Economics at Colby
Prior studies have expressed the value of location in real estate, but more recent studies have explored the influence that public transportation has had on housing prices. Access to public transportation is understood to increase the value of homes. Easier access to public transportation allows for shorter and more convenient commutes into or within cities. However, other studies have found that proximity to public transportation can also have adverse effects on property values. This paper investigates whether the implementation of the Greenbush Commuter line in Massachusetts in October 2007 increased the housing prices in Scituate, Ma--the furthest town from the …

Trophic Dynamics Of Flathead Catfish In The Missouri River Bordering Nebraska, Dylan R. Turner
Trophic Dynamics Of Flathead Catfish In The Missouri River Bordering Nebraska, Dylan R. Turner
School of Natural Resources: Dissertations, Theses, and Student Research
Understanding the trophic dynamics of large, riverine ecosystems is complex and requires knowledge from several inputs and outputs of the ecosystem. Most riverine ecosystems have been altered in some way whether through damming, channelizing, or diverting water. The Missouri River is not immune to these anthropogenic alterations. The river has dams throughout its middle portion and is channelized from Sioux City, Iowa to its confluence with the Mississippi River. Flathead Catfish pylodictus olivarius are one of the most ecologically harmful introduced species but little research has looked at the influence native populations of Flathead Catfish have on native prey populations …

Fish And Macroinvertebrate Response To Restored Off Channel Habitats On The Lower Platte River, Nebraska, Caleb Uerling
Fish And Macroinvertebrate Response To Restored Off Channel Habitats On The Lower Platte River, Nebraska, Caleb Uerling
School of Natural Resources: Dissertations, Theses, and Student Research
Anthropogenic alterations to large rivers ranging from impoundments to levees have caused many rivers to no longer access the floodplain. The ecological integrity of floodplain rivers depends on the interaction between main-channel and floodplain habitats. Fish communities inhabiting floodplain habitats are often dictated by the type of habitat and conditions within that habitat. As restoration projects are undertaken it is imperative that managers understand how fish and macroinvertebrates respond to these events. We collected fish, macroinvertebrates, and habitat parameters on two restored floodplain habitats on the lower Platte River, Nebraska to answer questions about aquatic community response to floodplain restoration …
Comprehensive Silica Removal With Ferric Compounds For Industrial Wastewater Reuse, Ehren D. Baca
Comprehensive Silica Removal With Ferric Compounds For Industrial Wastewater Reuse, Ehren D. Baca
Civil Engineering ETDs
Cooling towers, integrated circuit (IC) manufacture and reverse osmosis (RO) generate copious amounts of wastewater high in colloidal and reactive silica inhibiting on-site or synergistic reuse. Silica present in cooling water can reach solubility limits via evaporation and form impervious scale on heat transfer surfaces that decreases efficiency. When water is treated by RO operating at high rejection, silica forms difficult-to-remove scale on the membrane feed side in the form of glassy patches and communities of aggregate particles, inhibiting aspirations for zero liquid discharge. Current methods for silica scale mitigation include abundant dosing with chemical antiscalents or complex operating schemes. …
Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets
Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets
Journal of Ocean and Coastal Economics
Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …
Evaluating The Impacts Of Farmers’ Behaviors On A Hypothetical Agricultural Water Market Based On Double Auction, Erhu Du, Ximing Cai, Barbara Minsker
Evaluating The Impacts Of Farmers’ Behaviors On A Hypothetical Agricultural Water Market Based On Double Auction, Erhu Du, Ximing Cai, Barbara Minsker
Daugherty Water for Food Global Institute: Faculty Publications
Agricultural water markets are considered effective instruments to mitigate the impacts of water scarcity and to increase crop production. However, previous studies have limited understanding of how farmers’ behaviors affect the performance of water markets. This study develops an agent-based model to explicitly incorporate farmers’ behaviors, namely irrigation behavior (represented by farmers’ sensitivity to soil water deficit k) and bidding behavior (represented by farmers’ rent seeking l and learning rate b), in a hypothetical water market based on a double auction. The model is applied to the Guadalupe River Basin in Texas to simulate a hypothetical agricultural water market under …
