The effect of interactions between the sediment and water column on concentrations of microbes in streams is quantified with a one-dimensional, steady state model. The effects of nine main parameters describing the flow, sediment transport, and microbial growth and decay are encapsulated in two dimensionless parameters: the Damköhler number Da, or the ratio(More)
To improve the modeling of water quality in watersheds, a model is developed to predict resuspension of Escherichia coli from sediment beds in streams. The resuspension rate is expressed as the product of the concentration of E. coli attached to sediment particles and an erosion rate adapted from work on sediment transport. The model uses parameter values(More)
This study describes the development of WACCShed, an agent-based software platform that permits the systematic study of interactions among hy-drology, climate, and strategic human decision-making in a watershed over time. To illustrate the capabilities of the platform, findings are reported for a base-case application reflecting, in simplified form, the(More)
State's program: leadership, global awareness and understanding, systems thinking, and innovation and entrepreneurship. These outcomes, or pillars, are being integrated into curricular and co-curricular activities. The four pillar areas are introduced in a one-semester first-year seminar and reinforced in a two-semester second-year seminar. These seminars(More)
