The potential development of density currents in the Chicago River has been analyzed with the help of a three-dimensional hydrodynamic model. It was found that during the winter months, density currents can develop at the junction of the Chicago River with its North and South Branches. Such density underflows show a clear tendency to flow from the junction(More)
Chicago Waterways System (CWS) is a highly engineered and complex combination of natural rivers and artificial canal. Although not very long, CWS is famous for the engineering feat that directed its flow south away from the Lake Michigan into which it previously used to drain. In this research work two three dimensional models, Environmental Fluid Dynamics(More)
Bidirectional flows in a river system can occur under stratified flow conditions and in addition to creating significant errors in discharge estimates, the upstream propagating currents are capable of transporting contaminants and affecting water quality. Detailed field observations of bidirectional flows were made in the Chicago River in Chicago, Illinois(More)
RVR Meander was developed as a toolbox for modeling restoration and naturalization processes in rivers. This model includes Windows-based and Geographical Information System-based programs for analyzing and modeling planform migration of streams. In the past, several rivers have been channelized causing environmental and ecological problems. Restoration(More)
Asian carp eggs are semi-buoyant and must remain suspended in the water to survive, supported by the turbulence of the flow, until they hatch and develop the ability to swim. Analysis of the transport and dispersal patterns of Asian carp eggs will facilitate the development and implementation of control strategies to target the early life stages.(More)
D epartment faculty members have hit the road, pursuing projects that cross disciplines and cultures, putting the University of Illinois at the forefront of earth sciences on an international level. The impact of the Department's research and educational efforts is being felt worldwide through a series of collaborations between U. of I. and universities and(More)

Keywords: Stokes waves Free second harmonic Wave attenuation Graphical user interface MATLAB a b s t r a c t The ability to determine wave heights and phases along a spatial domain is vital to understanding a wide range of littoral processes. The software tool presented here employs established Stokes wave theory and sampling methods to calculate parameters(More)
Turbidity currents are a subset of gravity-driven flows and can be categorized as non-conservative gravity current, as it's driving media (entrained sediment) is in a continuous flux with the bed through erosion and deposition. Thus, turbidity currents are one of the main methods of sediment transport and dispersal in the submarine environment. This(More)
