Water underpins the survival of the ecosystem and of human civilization, which exists within a certain delicate balance. Water is especially crucial to the economic development of developing countries that happen to have limited water supplies. The state of Turkey once called As…

Dams provide immense societal benefits in the form of hydropower generation, flood control, and water supply. However, they also cause significant negative environmental impacts by altering the timing and magnitude of natural streamflow, limiting the transport of sediment, nutri…
Dissolved oxygen is an important parameter of water quality in aquaculture. Aeration has been known to improve oxygen levels and yields, but its use is uncommon in many developing world environments due to high costs. As a more effective implementation, this thesis presents the …
Research efforts on mixed bedrock-alluvial rivers primary focused on the bedrock incision and very few studies investigated the alluvial morphodynamics of such systems. To the best of my knowledge none of these models have been considered the spatial variability of the sediment …
A short (3 to 5-day) to mid-range (6 to 10-day) flood forecasting lead time is desired to increase the flood response and preparedness in flood-prone regions across the world. The major limitation of providing accurate flood forecasts of such lead times is mainly associated with…
Flood Impact Assessment (FIA) is an integral part of flood risk management (FRM) that requires extensive data collection and rigorous modeling. Elevation data is one of the main inputs for this venture that is often fulfilled by digital elevation models (DEM). DEM provides a con…
Making Water Pure: A History of Water Softening from Potash to Tide, is a history of water softening in the United States from 1860 through 1970. Water’s materiality, specifically its tendency to dissolve geological features, consistently interfered with labor processes, especia…
Glaciers are an integral part of polar and alpine landscapes, providing water, inorganic, and organic material subsidies to downstream ecosystems. These subsides regulate downstream temperature, streamflow, and sediment supplies. Warming in high altitude and high latitude enviro…
Anthropogenic nutrient loading has long been identified as potentially harmful to coastal waters surrounding the Hawaiian Islands, with excess nutrients being delivered by stream runoff as well as by inputs to groundwaters that exit the coast as submarine groundwater discharge (…
The sensitivity of water resources to climate change challenges water planning in the semi-arid western United States. Paleoclimate records illustrate the potential for hydrological change in response to warming, but questions remain regarding the sensitivity of Rocky Mountain s…
Ubiquitous presence of plastic debris in global oceans, lakes and streams/rivers is a result of large-scale use of plastics in this period of human history, known as plastic age. These micro-plastic particles could serve as scavenging agents in the removal of dissolved particle …
