Phosphorus Content And Release From Lake Sediments By Agitation, Hsien Ping Tang

Retrospective Theses and Dissertations

Man-made mixing in shallow lakes will resuspend bottom sediments and increase phosphorus concentration in the water body. The increase in phosphorus content may affect the lake productivity. During the course of this study, a better understanding of the water-sediment-phosphorus relationships of some shallow lakes in Central Florida was attempted. Column studies and batch experiments were used to investigate the effect of mechanical mixing on the release of phosphorus from bottom sediments collected from Lake Claire and Jessup. The particle size distribution and density distribution of the bottom sediments were studied and the release of phosphorus from each fraction was measured. …
