Quantitative impacts of lake-level stabilization on sediment and nutrient dynamics. By Johan F Gottgens. Abstract (Thesis) Thesis (Ph. D.)--University of Florida, (Bibliography) Includes bibliographical references (leaves )(Statement of Responsibility) by Author: Johan F Gottgens.   Current paradigms of reservoir ontogeny suggest that water-level fluctuations may increase sedimentary nutrient release, causing long-term eutrophication of water bodies formed by dryland flooding. Less is known of the changes in nutrient status following conversion of natural lakes into reservoirs. Here, we use historical hydrological and limnological data and paleolimnological .

Introduction. Phosphorus (P) is the main nutrient that controls the productivity of fresh waters, thus excessive external loading of P causes eutrophication problems (Schindler, ).The majority of P in lake ecosystems is usually stored in the bottom sediment, which can be recycled into the water column by various mechanisms (Pettersson, ; Søndergaard et al., ). river form and processes, including sediment transport and nutrient exchange (Poff et al., ). Morphological effects on the river channel (e.g., Kondolf and Matthews, ; Shields et al., ) that includes riverbed incision, riverbank instability, upstream erosion in tributaries.

Knowledge about historical nutrient accumulation and effect of environmental parameters on nutrient dynamics at the sediment–water interface in the lakes from this region is important to. The treatments were pure topsoil, a mixture of soil and biochar on top of the sediment, a mixture of biochar with top 20 cm of sediment, and a 75– cm layer of sediment directly on topsoil. In June , mixture of red fescue, Kentucky bluegrass, ryegrass, and white clover was sown to all plots with meat bone meal organic fertilizer. Consequences of sediment deficits and impacts on the river are (1) decrease in habitat heterogeneity (Kondolf ); (2) risk of river bank erosion (Rinaldi and Casagli ); (3) risk of damage to infrastructure, e.g., scouring bridge piers (Jäger et al. ); (4) lack of spawning habitats for salmonid fish species (Hauer et al. ) and. Eighteen sediment cores were dated radiochemically with Pb and Cs using γ-ray spectroscopy to determine modern and historic mercury accumulation rates for these subtropical wetland systems. ,Quantitative impacts of lake-level stabilization on sediment and nutrient dynamics: Coupling limnology with modeling, Ph.D. dissertation.
