A 2-dimensional numerical sediment transport model using erosion rates in undisturbed conditions has been developed and applied to calculating the suspended sediment concentrations and bed level changes in the Lower Fox River The model reduces inaccu

A theoretical description of the initiation of movement of sediments consisting of uniform-size, quartz particles is developed. These sediments behave in a noncohesive manner for coarse-grained particles but show cohesive behavior for fine-grained pa

Erosion rates and the properties of bulk density, average particle size, organic carbon content, and gas fraction were determined as a function of depth for 35 relatively undisturbed sediment cores from the Kalamazoo River. In most cores, strong stra

Measurements were made of the erosion rates and bulk properties of sediments from eleven sites in the Grand River in Michigan. High concentrations of gas, up to 5% by volume, were present in the sediments; this significantly affected the sediment bul

Long-term experiments were done in order to investigate nonlinear isotherms and interactive effects in the sorption of hydrophobic organic chemicals (HOCs) by sediments. In the isotherm experiments, it was demonstrated that the isotherms for all HOCs

In order to understand the transport and fate of hydrophobic organic chemicals (HOCs) in consolidated sediments and saturated soils, long-term (up to 512 d), one-dimensional, time-dependent diffusion experiments were done with a representative HOC, h

Experiments have been done in order to determine the effects of particle size and bulk density on the erosion of quartz particles. Average particle sizes ranged from 5 to 1,350 μm, while bulk densities ranged from approximately 1.65 to 1.95 g/cm³.

Recent work has demonstrated that both the adsorption and desorption of hydrophobic organic chemicals to sediments and soils can be quite slow and that chemical equilibrium may not be a good approximation in many real situations. By means of long-ter
