Water CirculationWater circulation in Lake Pontchartrain was characterized by wind, current, tide, turbidity, salinity, and temperature measurements. Satellite images were also studied to observe water quality over time. Water circulation resuspends polluted bottom sediments, and knowledge of circulation is key to predicting where the contaminants are likely to be concentrated. The objective was to construct a computer model of circulation patterns. Resuspension and transport of bottom sediments and pollutants due to wave action are important physical components to sediment distribution in Lake Pontchartrain. Two critical processes related to sediment transport in the lake are:
