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)
The size distribution of a particle suspension can be inferred from studying the diffracted light pattern produced by a laser beam that passes through the suspension. This involves solving an ill-posed linear system. Two previous versions of projection algorithms were tested by use of computer simulations and experiments. Both algorithms showed limitations(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)
