Effect of land use on sediment oxygen demand dynamics in blackwater streams

Sediment Oxygen Demand (SOD) is believed to be an important process affecting dissolved oxygen concentration in blackwater streams of the southeastern coastal plain. Because very few data on SOD are available, it is common for modelers today to take SOD values from the literature for use with dissolved oxygen (DO) models. In this study, SOD was measured in seven blackwater streams of the Suwannee River basin within the Georgia coastal plain for approximately 9 months. SOD was measured using 2four in-situ chambers, and was found to vary on average between 0.3-2.3 g O2/m-day for the seven study sites. SOD was found to vary significantly between the river basins within the Suwannee River, however land use was not found to be a driving force behind SOD values.
