Gis Analysis Application Of Flood Risk Map In Beijing, China, Yuxuan Liu
Honors Capstones
From the end of July to the beginning of August 2023, Beijing, China, affected by Typhoon "Dusuri" experienced the most precipitation in the Beijing area in 140 years of instrument measurement records. This event led to the evacuation of more than 1.8 million people across the Beijing-Tianjin-Hebei region and the tragic loss of 62 lives. After experiencing such fierce heavy rainfall and flood disasters, how to predict and prepare for such catastrophic events and avoid losses in the future has become a crucial problem. Geographic information systems (GIS) can integrate different layers of geospatial information and provide us with powerful …
Exploring The Role Of Near Channel Geospatial Attributes To Predict Suspended Sediment Concentration Patterns Across The Conus Region, Aaron J. Sigman
Exploring The Role Of Near Channel Geospatial Attributes To Predict Suspended Sediment Concentration Patterns Across The Conus Region, Aaron J. Sigman
All Graduate Theses and Dissertations, Fall 2023 to Present
High concentrations of suspended sediment (SSC) in a river can represent a critical water quality concern, reduce the storage capacity of reservoirs, and impact aquatic habitat. The total amount of sediment is calculated from a combination of river properties, including the amount of available sediment and the flow of water carrying the sediment. Water flow properties can be found using local information about the channel, however understanding the concentration of sediment in the river requires understanding the supply of sediment from the watershed. To understand where sediment is coming from, we examined over 1000 United States Geological Survey sites with …
Stable Water Isotopes Provide Insight Into The Spatial Variability Of As And U In Drinking Water Across The Northern Plains, Jacob Abbott
Stable Water Isotopes Provide Insight Into The Spatial Variability Of As And U In Drinking Water Across The Northern Plains, Jacob Abbott
Honors Theses
Arsenic (As) and uranium (U) contamination in drinking water affects millions of individuals across the US. This issue is particularly acute across rural populations where many people obtain drinking water from unregulated private wells. One specific location greatly affected by high levels of As and U in both surface and groundwater is the Northern Plains of the USA. However, the environmental and anthropogenic factors responsible for the mobilization and heterogeneous distribution of As and U in the waters of this region remain poorly characterized. Groundwater recharge sources and the flow path of water supplying surface water can strongly influence the …

Snow Distribution And Influence In Taylor Valley, Antarctica, Using Remote Sensing, Katherine Mcnulty, Peter Doran, Mark Salvatore, Suniti Karunatillake
Snow Distribution And Influence In Taylor Valley, Antarctica, Using Remote Sensing, Katherine Mcnulty, Peter Doran, Mark Salvatore, Suniti Karunatillake
LSU Master's Theses
The McMurdo Dry Valleys is the largest ice-free area in Antarctica, but seasonal snow covers the valley floors sporadically throughout the year. In this study, a model to estimate areal snow coverage from satellite imagery was created. An area-volume model was created to estimate the amount of snow water equivalent (SWE) from the snow area extracted from the imagery. Snow cover influences the total albedo, the hydrologic budget, and the soil moisture and soil temperature in Taylor Valley (TV). Quantifying snow precipitation in TV is challenging because snow redistributes with winds, sublimates, or melts within a short period. Previous estimates …
Hydrologic Outcomes For Ecological Meadow Restoration In The Northern Sierra Nevada, Emma Sevier
Hydrologic Outcomes For Ecological Meadow Restoration In The Northern Sierra Nevada, Emma Sevier
Cal Poly Humboldt theses and projects
Ecologically functioning meadows provide critical ecosystem services including improving a catchment’s water yield, flood dispersion and attenuation, fostering groundwater-dependent ecosystems, and creating natural fire breaks (Loheide and Booth 2011). Degradation from past and current land use has resulted in incised channels that change the magnitude and timing of watershed and meadow fluxes and cause water table decline. Process-based restoration (PBR) is an approach which leverages fluvial processes to increase restoration efficiency. Though PBR is a promising tool to restore degraded meadow ecosystems, more studies are needed to understand its hydrologic outcomes and whether hydrodynamic modeling can be used as a …
Predictors Of Summer Chloride Concentrations In Urban Aquatic Ecosystems, Georgianna S. Fischer
Predictors Of Summer Chloride Concentrations In Urban Aquatic Ecosystems, Georgianna S. Fischer
Honors Theses and Capstones
Urban aquatic ecosystems are highly threatened by excess concentrations of chloride (Cl-), which can negatively impact the biodiversity and functioning of aquatic ecosystems. High Cl- concentrations in most northern cities come primarily from road salt use for de-icing, in the form of NaCl. Specific pathways of runoff and hydrology of waterbodies will regulate Cl-concentrations in the months after the snowmelt season. This study attempted to understand the hydrologic controls on Cl- concentrations and identify how the hydrology of urban ecosystems may impact exposure to chloride in streams. To accomplish this, stream sites around the …
Characterizing Karst Mountain Watersheds Through Streamflow Response To Snowmelt, Daniel Meade Thurber
Characterizing Karst Mountain Watersheds Through Streamflow Response To Snowmelt, Daniel Meade Thurber
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The climate in many parts of the Western US is characterized by cold, wet winters preceding long, dry summers. In the absence of precipitation, water supplies in these regions are sustained by melting snow and mountain groundwater. Changes in regional climate can reduce snow accumulation, accelerate melt, and prolong dry periods, all increasing the importance of groundwater on summertime water availability. In mountainous regions with limestone and dolomite geology, bedrock formations can host significant karst aquifers comprising dissolution-enhanced karst conduits which play an outsized and variable role in how precipitation is translated into streamflow. In this study, we considered an …

The results confirmed effective inundation performance in these floodplain or wetland-related CE …
Highly Variable Rainfall-Runoff Patterns Across Burned Mountainous Watersheds In The Colorado River Headwaters, Haley Anne Canham
Highly Variable Rainfall-Runoff Patterns Across Burned Mountainous Watersheds In The Colorado River Headwaters, Haley Anne Canham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wildfires can contribute to enhanced flooding, erosion, debris flows, sediment transport, and water quality changes that impact downstream infrastructure, water users, and aquatic habitat. With increasing wildfire risk in the western U.S. due to a changing climate, understanding post-wildfire rainfall-runoff patterns and controls is critical for continued water resources security. To improve understanding of post-wildfire rainfall-runoff patterns and controls, we developed a transparent, repeatable analysis framework to collect precipitation and streamflow data, identify paired rainfall-runoff events, and analyze these events to evaluate post-wildfire rainfall-runoff patterns and controls. To automate the rainfall-runoff event identification, the Rainfall-Runoff Event Detection and Identification (RREDI) …

Giving Form To Flow: Modeling The Paleohydrological Context For Human Settlement And Water Use In The North-Central Coast Of Peru, Elizabeth Leclerc
Electronic Theses and Dissertations
Within coastal Andean archaeology there is a growing emphasis on the roles of hydrology and hydrological knowledge in Andean strategies for water management, settlement, and land use. Hydrological methods can not only help reconstruct past water environments but also illuminate the influence of changing climates and conditions in the Andean highlands on coastal water flows. Through a case study of the Supe River basin in north-central coastal Peru, focusing on the period from 5000 to 3000 calibrated radiocarbon years before present (cal. BP), I review several hydrological methods useful for archaeological study. I then combine these to develop a paleohydrological …
Interventions Towards Sustainable Watershed Management As Demonstrated By Hydrologic Simulation, Shan Zuidema
Interventions Towards Sustainable Watershed Management As Demonstrated By Hydrologic Simulation, Shan Zuidema
Doctoral Dissertations
Increasing population, changing climate, and on-going legacies of environmental mismanagement motivate our need for deeper understanding of the process and limits of adaptation towards sustainable management of water resources. Movements towards open-science and transdisciplinary research have enabled deeper assessments of the co-evolution of human society and changing landscapes. Policies and decisions enabling environmental restoration or sustainable resource use have been actively pursued for decades. The social barriers that prevent adaptations to succeed are deep and entrenched, but equally important are the physical barriers. Successful adaptations in water resource management need to explicitly consider the joint interactions of intervention magnitude, or …

The Music Of Rivers: How Climate, Land Use, And Disturbances Tune The Frequencies And Volumes Of Streams Worldwide, Brian Charles Brown
The Music Of Rivers: How Climate, Land Use, And Disturbances Tune The Frequencies And Volumes Of Streams Worldwide, Brian Charles Brown
Theses and Dissertations
The amount of water flowing through streams and rivers changes through time. The seasonality and duration of these changes can have profound impacts on human freshwater availability, aquatic habitat, and biogeochemical cycling. Numerous factors are thought to influence streamflow regime, including drainage basin area, temperature, precipitation, and land cover. Few of these qualities have remained untouched, either directly or indirectly, by expanding human activities. Altered climate, sweeping changes to large portions of the earth's surface, and the construction of dams and other infrastructure have fundamentally altered streamflows worldwide. Understanding the nature of these changes, both globally and regionally in the …

Characterization Of Problematic Red Clay Soils In Arkansas For The Purpose Of Onsite Wastewater System Placement, Bailey Darnell
Characterization Of Problematic Red Clay Soils In Arkansas For The Purpose Of Onsite Wastewater System Placement, Bailey Darnell
Graduate Theses and Dissertations
Distinguishing between red-clay soils that are non-expansive and can reduce and red-clay soils developing in problematic red parent material, which are expansive, but also non-reducing, is key for proper on-site wastewater system placement. The Arkansas Department of Health allows for the placement of on-site wastewater systems in certain red-clay soils that have the potential to reduce, but only in the Ozark Highlands [Major Land Resource Area (MLRA) 116A], which is referred to as the red-soil exception. There is currently little scientific data to support the geographic restriction of the red-soil exception. The objectives of this study were to: i) confirm …

Bridging Data Gaps For Strategic Conservation Of Gulf Of Mexico Coastal Region Landscapes, Andrew Challen Shamaskin
Theses and Dissertations
The Gulf Coast Region (GCR) of the United States holds immense ecological and cultural value. However, constant environmental changes, from sea-level rise and hurricanes to the Deepwater Horizon oil spill in 2010, threaten many of the values that define the region. Additionally, recent financial settlements from civil and criminal penalties of the Deepwater Horizon oil spill have created an unprecedented opportunity to fund conservation throughout the region. With such a large area of interest (over 700,000 km2) and so many conservation priorities throughout the GCR, there is a great need to strategize which lands are most efficacious for conservation to …

Effects Of Historical Land-Use Change On Surface Runoff And Flooding In The Amite River Basin, Louisiana, Usa Using Coupled 1d/2d Hec-Ras–Hec-Hms Hydrological Modeling, Alexandre G. H. Cowles
LSU Master's Theses
The Amite River Basin is a largely rural watershed spanning parts of four counties in southern Mississippi and seven parishes in southeast Louisiana, with basinwide imperviousness increasing from 0.82% in 1938 to 3.85% in 2016. The Basin has been the subject of significant research interest since catastrophic flooding in 2016 caused 13 deaths and widespread damages. Rapid development in recent decades has led to an expansion of impervious surfaces in Baton Rouge and surrounding areas, encroaching on floodplains and wetlands. At the basin scale, differences in flooding due to impervious cover changes were found to be somewhat limited, particularly along …
Hydrologic Modeling Of A Small Wetland Complex To Inform Estimates Of Phosphorus Retention, Isabelle C. Augustin
Hydrologic Modeling Of A Small Wetland Complex To Inform Estimates Of Phosphorus Retention, Isabelle C. Augustin
UVM Patrick Leahy Honors College Senior Theses
Phosphorus (P) is an important nutrient in ecosystems and is often limiting in freshwater systems and the human application of P in agriculture has made P management a priority to maintain freshwater ecosystem health. Previous studies suggest that small wetlands play a disproportionately large role in landscape-scale nutrient processing. Modeling watershed P dynamics requires estimates of water budgets within the areas of interest. The objective of this work is to model the inflow, outflow, stage, and storage relationships of a small wetland with an active beaver dam in the Prindle Brook floodplain in Addison, VT using HydroCAD. A sensitivity analysis …

Understanding The Effect Of Climate And Hydrometeorological Extremes On Natural And Human-Induced Hydrosystems, Jeongwoo Hwang
Dissertations and Theses
The contemporary hydrosystems of the United States involve a complex combination of natural and modified basins in the presence of changing climate and anthropogenic impacts. An enhanced understanding of the interdependence between climate forcings, human-induced interventions, and water balance in both natural and modified basins are essential for developing reliable and resilient hydrosystems and for better water resources management. In response, this dissertation focuses on investigating the hydroclimatology of natural and modified basins across the contiguous United States. It has three research objectives: (1) to explain flow alterations due to anthropogenic activities, especially dam operations, in modified basins and understand …
Spatiotemporal Patterns In Water Yield From The Humid Puna: A Case Study In The Agrarian District Of Zurite, Perú, Wyeth Wunderlich
Spatiotemporal Patterns In Water Yield From The Humid Puna: A Case Study In The Agrarian District Of Zurite, Perú, Wyeth Wunderlich
Cal Poly Humboldt theses and projects
The humid puna is a seasonally dry alpine grass- and shrub-land biome that exists at the altitudinal limits of plant survival, hosts peat-forming wetlands known as bofedales, and yields water to streams used by small and large communities throughout the central and southern Peruvian Andes. Despite the importance of the humid puna in supplying water resources, particularly to perennial streams, few studies have quantified water yield and no studies have explored relationships between the structure of puna landscapes and spatial patterns in water yield. Zurite (population: 3,640, elevation: 3,011 m.a.s.l., annual precipitation: 855 mm) is an agrarian district in …
Nitrogen Dynamics And Transport Along Flowpaths In A Rural Wetland-Stream Complex, Colton Kyro
Nitrogen Dynamics And Transport Along Flowpaths In A Rural Wetland-Stream Complex, Colton Kyro
Graduate Student Theses, Dissertations, & Professional Papers
Human activities have doubled the rate of nitrogen inputs onto the landscape resulting in elevated nitrogen concentrations in our streams. Anthropogenically applied nitrogen is largely transported to stream networks via groundwater movement. Groundwater discharge occurs in distinct points along a stream but whose influences can often persist far beyond that area due to insufficient biogeochemical removal of imported nitrogen potentially causing alterations in community structure and precipitating large algae blooms. To understand the factors governing nitrogen abundance in a historical polluted stream, I used a mass-balance approach to quantify groundwater-surface water interaction and the magnitude of groundwater nitrogen input and …

Human And Climate Impacts On Flooding Via Remote Sensing, Big Data Analytics, And Modeling, Eunsang Cho
Doctoral Dissertations
Over the last 20 years, the amount of streamflow has greatly increased and spring snowmelt floods have occurred more frequently in the north-central U.S. In the Red River of the North Basin (RRB) overlying portions of North Dakota and Minnesota, six of the 13 major floods over the past 100 years have occurred since the late 1990s. Based on numerous previous studies as well as senior flood forecasters’ experiences, recent hydrological changes related to human modifications [e.g. artificial subsurface drainage (SSD) expansion] and climate change are potential causes of notable forecasting failures over the past decade. My dissertation focuses on …

Future Hydrological Failure Probability Of Dams In New England Under Land Use And Climate Change, Iman Hosseini-Shakib
Future Hydrological Failure Probability Of Dams In New England Under Land Use And Climate Change, Iman Hosseini-Shakib
Doctoral Dissertations
Floods lead to the overtopping of dams which is the main cause of dam failures and can result in significant loss of lives and property. This study investigates how the hydrological failure probability of dams in New England may change with future changes in climate and land use. Non-stationarity of future precipitation caused by the anthropogenic climate change and altered watershed concentration times caused by anthropogenic alterations such as urbanization, industrialization or deforestation can impact the mechanisms of runoff production and transfer. This can potentially change the frequency, magnitude, or duration of floods. Therefore, due to different flood patterns and …

Probabilistic Approach To Water, Sediment, And Nutrient Connectivity For Advancing Watershed Modelling, David Tyler Mahoney
Probabilistic Approach To Water, Sediment, And Nutrient Connectivity For Advancing Watershed Modelling, David Tyler Mahoney
Theses and Dissertations--Civil Engineering
The goal of this dissertation is to represent the spatial and temporal domains of water, sediment, and nutrient flux and pathways within fluvial and watershed settings. To complete this goal, we integrate connectivity theory into watershed model structures to simulate water, sediment, and nutrient movement at the fundamental unit they occur. Fluvial-based sediment and nutrient flux is an important driver of global sediment and nutrient budgets, and the quantification of which serves as an ongoing challenge to limnologists, engineers, and watershed managers. Watershed models have been richly developed over the past century, but are currently restrained by problems related to …
