We discuss a visualization system for the comparison of simulated and measured water quality. The system extends SCIRT (Site Characterization Interactive Research Toolkit), an interactive system originally developed at the NSF Engi-1 Introduction Management of environmental quality requires analyses of complex processes which often defy direct insight. The(More)
This paper describes our experience in designing and building a tool for visualizing the results of the CE-QUAL-ICM Three-Dimensional Eutrophication Model, as applied to water quality in the Chesapeake Bay. This model outputs a highly multidimensional dataset over very many timesteps – outstripping the capabilities of the visualization tools available to(More)
BACKGROUND: In recent years new ideas for nutrient management to control eutrophication in estuarine environments have been under consideration. One popular approach being considered in the Chesapeake Bay Program is called the “top down” approach based on the premise that restoring algal predators, such as oysters and menhaden, will limit excess(More)
Approved for public release; distribution is unlimited. Abstract: The Corps of Engineers Integrated Compartment Water Quality Model (CE-QUAL-ICM or simply ICM) was designed to be a flexible, widely applicable eutrophication model. Ecopath with Ecosim (EWE) is a freely distributed network model supported by the Fisheries Centre, University of British(More)
Environmental Laboratory Approved for public release; distribution is unlimited. ABSTRACT: The CE-QUAL-ICM three-dimensional eutrophication model was applied to Lake Wash-ington, northwestern Washington State, for the period 1995-1997. Transport processes were obtained from the companion CH3D-WES hydrodynamic model. The model activated 18 state variables in(More)
Algal growth kinetics based on internal phosphorus concentration were incorporated into an existing eutrophication model. Application to a closed system resulted in damped oscillations in algal biomass and phosphate relative to a model with fixed composition. Peak biomass did not differ substantially, however, from that attained using a model with fixed,(More)
