Cyanobacterial harmful algal blooms (cyanoHABs) are becoming more frequent and intense due to anthropogenic activities. CyanoHABs degrade water quality and impose threats to human and ecosystem health. Yet, we do not fully understand under which circumstances a bloom turns toxic…

Lake Erie is one of the five Laurentian Great Lakes, that includes three basins. The central basin is the largest, with a mean volume of 305 km2, covering an area of 16,138 km2. The ice used for this research was collected from the central basin in the winter of 2010. DNA and RN…
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 …
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…
Eutrophication is defined as 'an increase in the rate of supply of organic matter (OM) to an ecosystem'. In estuaries, this can take two forms: an increase in allochthonous and an increase in autochthonous OM. The goal of this dissertation was to use spectrofluorometry, as excit…
Factors regulating composition and relative abundance in phytoplankton communities were investigated in an ancient lake with a highly endemic food web. Lake Matano has genera diversity (21) similar to tropical lakes, but low phytoplankton biomass (0.0162 μg/L). Vertical mixing p…
Lake of the Ozarks was constructed for hydropower and has become a popular recreational river-reservoir in the Ozark Plateau of Missouri. Wide spread use of septic tanks in porous soils of the region poses a threat to public health via leaching into drinking wells and coves used…
Aquatic macroinvertebrates are well-established biological indicators of water quality and a major component of water quality assessment of flowing waters because of their ability to detect and integrate natural and anthropogenic changes in physical and chemical habitat. The New…
Onondaga Lake in Syracuse, New York was once considered to be the most polluted lake in North America. Since the lake’s placement on the EPA’s superfund site list in 1994. The purpose of this study was to determine historical and surficial sediment concentrations of organic poll…
The purpose of this study is to build a library of flood inundation extent in Bangladesh based on river height gauge levels, satellite imagery, and digital elevation models. The ability to forecast the extent of inundation during floods will help decision-makers to manage extrem…
Due to its geographical location and socioeconomic conditions, the country of Bangladesh in vulnerable to the hazard of riverbank erosion, which poses a significant threat to homes, property and livelihoods. In recent years, the government of Bangladesh has intensified efforts t…
