| Urban rivers are plagued with a variety of ailments ranging from hydraulic modifications, organic matter enrichment, loss of biodiversity, toxic pollutant loads, and chronically low dissolved oxygen (DO) concentrations. Utah's Jordan River is no exception, and the purpose of this research was to better understand the chronic DO deficits found in the lower river flowing through Salt Lake City. The primary goals were focused on identifying and quantifying DO dynamics in the water column and at the sediment-water interface, macronutrient dynamics, sediment methane production, sediment organic matter (OM) standing stocks, size speciation of sediment OM, and the estimation of OM loads associated with primary production in the Upper Jordan River. Solids, liquids, and gases were investigated to identify linkages and to conduct mass balances on both DO and OM to better understand the urban Jordan River. |
