Climate variability and extreme events continue to worsen resulting in significant impacts to society and the environment. Quantifying precipitation variability, streamflow, and extreme events at local scale is crucial for local planning and management due to spatial and tempora…
Fresh water or wai was an integral aspect of ancient Hawaiian culture. For thousands of years, water was collected, stored, and directed throughout the land from the mountains to the ocean through a sequence of rivers, lakes, or streams. Today, the Board of Water Supply (BWS) se…
Hydropower dams have received increased global attention due to their detrimental socioenvironmental ramifications, resulting in increased concerns as to whether their energy benefits can outweigh the detrimental consequences. To fulfill rising energy demands driven by rapid pop…
Within the northern Great Plains of the United States is the southeast Prairie Pothole Region (SEPPR), an important habitat for waterfowl, pheasants, deer, and many unique species that cannot be found anywhere else in the regional landscape. There are millions of wetlands in thi…
The Columbia River basin is a large transboundary basin located in the Pacific Northwest, straddling the US-Canadian border. The basin spans seven US states and one Canadian province, encompassing a diverse range of hydroclimates. Strong seasonality and complex topography, combi…
This study explores 20 years of Minnesota regional phosphorus (P) management data across agricultural landscapes and how these are modeled by the Minnesota Phosphorus Index (MNPI). Nutrient-loading and farm management records from 1999-2019 were compiled across 17 different Minn…
Anthropogenic climate change has resulted in more frequent and higher intensity storm events. These events will increase flooding, resulting in property damage, evacuations, and in extreme cases, death. The Midwest United States has experienced increased temperatures and oscilla…
Climate change and human activities are already affecting water resources in the Great Lakes region. A further projected increase in high-intensity precipitation events may cause flooding and added stress on urban infrastructure. In addition to climate, land use may change to ac…
Expanding agricultural lands and urbanization threaten the integrity of both natural aquifers and surface waters, and in turn, the multitude of water services they provide. The goal of this work is to investigate tradeoffs between water services and economic considerations in th…
The role of climatic and anthropogenic drivers in groundwater storage depletion and recovery in California’s Central Valley has been investigated. Specifically, the dissertation addresses three research questions: (1) How does climate change impact the groundwater storage? (2) C…
The environmental impacts of COVID-19 and the “new normal” of working from home are being explored in the scientific community. However, there is currently no published study on the COVID-19 impacts to nitrate load via septic systems. This study aims to determine the increase of…
This paper investigates climate change impact on the water resources in the Greenbrier basin using a distributed hydrological model VIC and future climate series. The GCM outputs under the SRES A2 greenhouse gas emission scenario is downscaled and bias-corrected by the BCCAQ met…
Monthly unimpaired flow calculations have been at the heart of hydrologic forecasting and water management in California for decades. Yet only recently have daily unimpaired flow calculations been applied directly to state-level water management policy. In 2018, the California S…
Phosphorus is an essential nutrient that allows life in water to flourish, but changes in phosphorus supplies are not well understood in remote watersheds. In mountain environments, remote watersheds contain critical high-quality water supplies and unique ecosystems, but excess …
Knowledge of the dynamics of rivers and reservoirs is important to help manage the impacts of climate change and anthropogenic activities on water resources, which are intimately tied to human well-being, economic wealth and environmental health. However, ground-based measuremen…
The Spring River, located within the Interior Highlands, supports one of the most biodiverse fish faunas (137 species) within Arkansas. However, threats to the fish communities include chronic pasture land-use and potential fish introductions from farm ponds within the watershed…
Meandering rivers across the globe present a striking similarity in their alignment, and this pattern has intrigued scientific curiosity for almost a century. However, still very little is known about ‘unconventional’ river meanders with a “zigzagging” planform appearance, but w…
The significance of water cannot be overstated. Water is necessary for the metabolic functioning of all life. From the earliest records of human social life, water has determined where people settled and how societies formed. Yet the biological role of water does not capture its…
