Infill vs greenfield development are key processes to understand in this study. For years the city of Grand Forks, ND has been trying to find a way to tackle the cost effectiveness of property value on infill vs. greenfield development. We set out to help inform them in their decision making process by creating a model looking at the property values over a span of 26 years. We want to …

Evaluation Of Staten Island's Wetland Services And Environmental Costs Of Removal, Gracyn Cole

Arts & Sciences Undergraduate Showcase

In 2017, the New York City Council approved a zoning variance allowing the demolition of 28-acres of wetlands near Staten Island’s Graniteville neighborhood in order to build a BJ’s Wholesale grocery store, a gas station, and a parking lot for 835 cars. This action raised concern for the people living within this neighborhood due to the amount of water detention the wetlands provide during natural disaster events. Specifically, the Graniteville Wetlands have protected the surrounding neighborhoods from severe natural disasters such as Hurricane Sandy which, in turn, has allowed these neighborhoods to contribute less to flood mitigation through infrastructure and …

Use Of Hyperspectral Remote Sensing To Estimate Water Quality, Mbongowo J. Mbuh

Geography & Geographic Information Science Faculty Publications

Approximating and forecasting water variables like phosphorus, nitrogen, chlorophyll, dissolved organic matter, and turbidity are of supreme importance due to their strong influence on water resource quality. This chapter is aimed at showing the practicability of merging water quality observations from remote sensing with water quality modeling for efficient and effective monitoring of water quality. We examine the spatial dynamics of water quality with hyperspectral remote sensing and present approaches that can be used to estimate water quality using hyperspectral images. The methods presented here have been embraced because the bluegreen and green algae peak wavelengths reflectance are close together …

Monitoring And Modeling The Effect Of Agricultural Drainage And Recent Channel Incision On Adjacent Ground Water-Dependent Ecosystems, Philip J. Gerla

Geology and Geological Engineering Faculty Publications

Channel incision isolates flood plains, disrupts sediment transport, and degrades riparian ecology. Reactivation and periodicity of incision may affect the water table and hydrological conditions far beyond the stream margin. Long-term incision and its recent acceleration along Iron Springs Creek, North Dakota, USA, has affected adjacent ecosystems. An agricultural surface drain empties directly into the original spring-fed source of the creek, which triggered channel erosion both up- and downstream. Historical maps, recent LiDAR, and field surveying were used to characterize incision since ditch excavation in 1911. Although the soils are sandy, small hydrological gradients impede natural drainage in the surrounding …

Reading The Landscape In Antler, North Dakota: Repeat Photography In An Atrophying Northern Plains Town, William A. Wetherholt, Gregory S. Vandeberg

Geography & Geographic Information Science Faculty Publications

This study presents repeat photography as an effective method to construct a narrative of change for a cultural landscape. The technique of repeat photography is the process of revisiting the vantage point of a historic photograph and capturing a contemporary image. This chapter focuses on the town of Antler, North Dakota, which has lost more than 85% of its population in the last 50 years (the 2016 estimated population was 25). Repeat photography with eleven historic photographs in Antler began to uncover a story of abandonment and change over the last century. It is this telling of a story through …

Late Summer Glacial Meltwater Contributions To Bull Lake Creek Stream Flow And Water Quality, Wind River Range, Wyoming, Usa, Jeffrey Vanlooy, Gregory S. Vandeberg

Earth System Science and Policy Faculty Publications

The Wind River Range in Wyoming contains more glacial ice than any other location within the USA’s Rocky Mountain states of Colorado, Idaho, Montana, and Wyoming. Bull Lake Creek watershed in the southeast portion of the range contains five major (0.6–1.5 km2) glaciers along with numerous smaller glaciers that contribute to the Wind River. Field measurements were made of discharge from the Knife Point and Bull Lake Glaciers to determine the contribution of glacial meltwater to the river system. Water samples were collected and analyzed for stable isotopes, major ions, nutrients, and selected trace elements. Meltwater from the two glaciers …

A Volumetric Water Budget Of Devils Lake (Usa): Non-Stationary Precipitation–Runoff Relationships In An Amplifier Terminal Lake, Paul E. Todhunter

Geography & Geographic Information Science Faculty Publications

Devils Lake, a terminal lake in eastern North Dakota, rose more than 9 m between 1992 and 2013, producing a 286% increase in lake area, and causing more than US$1 billion in direct damages. An annual volumetric lake water budget is developed from monthly hydroclimatological variables for the period 1951–2010 to investigate the rapid lake expansion. The lake is an amplifier terminal lake in which long-term climatic changes are amplified by positive feedback mechanisms, causing the lake to transition from a precipitation-dominated to a runoff-dominated water budget. Factors specific to the Devils Lake Basin further amplify this positive feedback relationship. …

This twentieth anniversary of the Red River Flood of 1997, which devastated the town of Grand Forks, North Dakota and surrounding areas, gives a new generation of Grand Forksers and Red River valley citizens the occasion to look backward so that they can look forward. Taking stock of how the city and its people have changed in these last twenty years offers us a new chance to envision the future of Grand Forks and the …

Mean Hydroclimatic And Hydrological Conditions During Two Climatic Modes In The Devils Lake Basin, North Dakota (Usa), Paul E. Todhunter

Geography & Geographic Information Science Faculty Publications

Proxy variables from palaeolimnological studies of lakes in the Prairie Pothole Region of North America have been used to infer large oscillations during the late Holocene between longer periods of high-salinity–dry conditions and shorter periods of low-salinity–wet conditions producing a normative pattern marked by the absence of hydrological stability. Studies of the historical rise in lake level at Devils Lake have identified 1980 as a transition point between two such hydroclimatic modes. This study uses multiple datasets to characterize the mean hydroclimatological and hydrological conditions of these two climatic modes. Mode 1 is a cool and dry phase, and mode …

Natural Hydroclimatic Forcing Of Historical Lake Volume Fluctuations At Devils Lake, North Dakota (Usa), Paul E. Todhunter, Rhonda Fietzek-Devries

Geography & Geographic Information Science Faculty Publications

Devils Lake, a terminal saline lake in eastern North Dakota, has experienced catastrophic flooding over the past two decades producing direct damages in excess of $1 billion ($USD). We use three long-term datasets to examine the temporal coherence between historical lake fluctuations and basic hydroclimatic drivers. Monthly precipitation and mean monthly air temperature data are used to characterize long-term precipitation delivery and evaporative demand. Monthly water balance data for a representative location are used to assess basin soil moisture conditions. A lake volume time series documents lake volume fluctuation in response to long-term precipitation and regional soil moisture conditions. Three …

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 …

Bias In Severe Thunderstorm And Tornado Warnings Issued By The National Weather Service In The Doppler Radar Era: A Spatial-Temporal Evaluation, Gary S. Votaw

Theses and Dissertations

A climatology of severe thunderstorm (damaging wind and/or hail) and tornadoes in the United States has established the location of the areas of highest frequency of occurrence. This climatology was attained through analysis of a basic data source, that of observed events, which carries many associated biases. Among these biases is the requirement that someone be on hand to witness the event no matter what time of the day or night, the assumption that the observer had sufficient visibility to see the event clearly, and whether there was something available on location to damage. In this study I use an …

Snowpack Control Over The Thermal Offset Of Air And Soil Temperatures In Eastern North Dakota, Andrew Grundstein, Paul E. Todhunter, Thomas Mote

Geography & Geographic Information Science Faculty Publications

[1] The close relationship between air and ground temperatures has been used to reconstruct paleoclimate conditions from ground temperatures. Unfortunately, the presence of snow decouples air and ground temperatures and obscures their relationship. The objective of this paper is to investigate the role that snowpack conditions play in affecting the relationship between air and soil temperatures. The annual thermal offset between mean annual soil and air temperatures is examined over a 12 year period (1990–2002) at Fargo, ND, using observed soil temperatures along with simulations from a physically based snowpack model. Early season snow cover does not necessarily lead to …
