Nonstationarity in the means and extremes of water resources (e.g., streamflow) due to climate change presents challenges to water resources management and planning. Changes in hydrologic variables such as streamflow critically impact infrastructure, water use planning and adapt…

This project examines how indigenous agrarian communities in Mexico’s Central Highlands used both legal and extralegal strategies to maintain their access to water while facing increasing environmental changes and competition from private landholders, cities, and other indigenou…
This dissertation presents an in-depth study of one of the most controversial endangered species in United States history, and advances a theoretical framework for understanding the emergence of environmental problems in contemporary society. The delta smelt is a tiny fish found…
The White Clay Creek watershed in southeastern Pennsylvania and northern Delaware plays a vital role as an important drinking water source for communities in the watershed and as habitat for wildlife. As a critical link in the Delaware Estuary system it provides economic benefit…
Unlike most states west of the 100th meridian, California has, until recently, never enacted a comprehensive set of regulations to govern consumptive use of groundwater resources, even though groundwater provides between 40 percent and 60 percent of the water used by residents, …
Seasonal and ephemeral surface water resources are essential to human consumptive uses and the nourishment of aquatic habitats, but they are increasingly threatened by climate-change related impacts. Western North America, for example, has already experienced significant decline…
Silver carp (Hypophthalmichthys molitrix) is an invasive species to the United States that is capable of spawning multiple times within a single reproductive season. In 2016, an abundance of age-0 silver carp, with size-structure indicative of multiple hatch dates, were captured…
Movement and dispersal of migratory fish species is an important life history characteristic that can be impeded by navigation dams. Although habitat fragmentation may be detrimental to native fish species, it can act as an effective and economical barrier for controlling the sp…
The United States and the world have recently been challenged with the disparate effects of COVID-19 and the continual killings of unarmed Black men and women across the nation. A history of anti-black racism has led to systemic structures of inequity that thread throughout inst…
This research deals with setting up a GIS and hydrological modeling based approach for sustainable water resources management in the West Bank of Palestine. This water sustainability approach took into consideration the water balance, the social, the economic, the demographic, t…
This thesis examines the recent emergence of “vulnerability to climate change” as a framework for development in rural Guyana. More specifically, I study experts’ use of the term “vulnerability” throughout the implementation of four recent water infrastructure projects on Indige…
For more than a century, a large volume of gold-mining tailings was deposited in Whitewood Creek and the Belle Fourche River, tributaries to the Cheyenne River in western South Dakota. Much of it still remains, and field and historical evidence indicates continued remobilization…
The American Southwest is one of the most rapidly growing regions of the United States, as are similar arid regions globally. Across these landscapes where surface water is intermittent and variable, groundwater aquifers recharged by surface waters become a keystone resource for…
Climate variability and its impacts on the agriculture system is clearly evident in Ghana. Weather and seasonal climate forecast information service has been in operation for some time in the country. However, farmers generally do not find the information useful for their farm-l…
Underground utilities and wastewater collection systems deteriorate over time demanding utility owners to involve in continuous revisions and development of their asset management frameworks to maintain the functionality of their assets. In any asset management framework, inspec…
A Colina do Castelo, onde se inclui Alfama, é uma zona da cidade de Lisboa rica em recursos hidrológicos, frios e termais, que foram aproveitados ao longo dos tempos pelas populações e onde se encontram identificadas dezenas de estruturas de abastecimento de águas de diferentes …
The common practices for planning and management of Water Resources Systems (WSSs) are challenged in the last decades by global climate change processes which are observed around the world in increasing frequencies. Climate change is manifested by climate variability, temperatur…
Human-caused changes in water use, emissions, and land cover have increasingly impacted the natural and built environments. As a result, the natural hydrologic cycle has been disrupted, causing changes in the quantity and quality of water, extreme events (i.e., droughts and floo…
Growing food demand has been the primary cause of increasingly unsustainable water consumption in the world’s breadbasket regions. This unsustainable demand can have steep human and environmental consequences, leading to physical and economic hardship among vulnerable communitie…
