Coagulation is a complex processes where multiple interactions occur between an infinite number of particles. In the past, scientists generally have taken a reductionist approach to complex problems. However, as alluded to by Gallagher and Appenzeller (1999), many complex systems are best interpreted using an "integrative agenda". Coagulation has been studied in this context by many researchers, particularly physicists, who view coagulation as a self-similar or fractal phenomenon. Results from such studies indicate that the small-scale interactions between particles give rise to large-scale self-organization. In addition, information about the small-scale interactions can be deduced from properties of the large-scale features.

520 $a Coagulation is a complex processes where multiple interactions occur between an infinite number of particles. In the past, scientists generally have taken a reductionist approach to complex problems. However, as alluded to by Gallagher and Appenzeller (1999), many complex systems are best interpreted using an "integrative agenda". Coagulation has been studied in this context by many researchers, particularly physicists, who view coagulation as a self-similar or fractal phenomenon. Results from such studies indicate that the small-scale interactions between particles give rise to large-scale self-organization. In addition, information about the small-scale interactions can be deduced from properties of the large-scale features.
520 $a In this dissertation, I will examine how results on the fractal nature of coagulation can be extended to natural and engineered aquatic systems where initial conditions, sedimentation, and zooplankton grazing affect the self-similar characteristics of the coagulation process. I will show how bimodal initial conditions lead to non-universal scaling characteristics of particle distributions when the kinetics of coagulation are not governed by particle size. I will illustrate how particles undergoing steady-state coagulation and settling poise themselves in a self-organized critical state and arrange themselves into self-similar particle distributions with moments that obey power-laws with depth. I will show how zooplankton grazing affects the self-organized state of particles undergoing steady-state coagulation and settling. I will also show how the scaling characteristics of zooplankton grazing and settling of particles result in an uncoupling of vertical mass flux from the processes of coagulation and fragmentation. Data from natural systems including Lake Zurich, the Arabian Sea, the Equatorial Pacific, and the North Atlantic are used to test theoretical predictions.
520 $a This work is relevant to studies on biogeochemical cycles where particles serve as a phase for elemental transport between sediment, air, and water. The results also extend to water quality engineering where particles are an undesirable component of waste-water, channel discharge, and blooms of noxious protozoa and plankton.
