This report documents mathematical model studies conducted to evaluate the environmental impacts of Hurricane Katrina. One of the primary environmental concerns associated with Hurricane Katrina was the impacts to ecological resources stemming from contaminants that were released into the floodwaters and subsequently pumped into surrounding water bodies outside the levee system. Contaminant concentrations within the water column and sediment bed were computed for two environmentally important water bodies, Lake Pontchartrain and Violet Marsh, both of which received pumped floodwater effluents following Hurricane Katrina. Two different mathematical models were used to simulate contaminant concentrations within the lake and marsh. Contaminant concentration information in these two systems was used to draw conclusions regarding the environmental consequences of contaminant releases. The models were used to determine the consequences of dewatering the floodwaters of Hurricane Katrina, with or without levee failure.
