Abstract : Sediment oxygen demand (SOD) and related processes control many water quality conditions. An understanding of SOD processes and their quantification is needed to assess the effects of US Army Corps of Engineers (CE) projects on sediment-water interactions and water quality. The US Army Engineer Waterways Experiment Station (WES) is presently developing methods to quantify SOD and determine its effect on water quality. A literature review and other papers presented at a WES workshop give an understanding of current techniques used to measure SOD and nutrient flux and determine the current state of the art of SOD research. Three major areas are examined by the papers: (1) the physical, chemical, and biological processes critical to SOD; (2) a predictive model for SOD; and (3) the techniques presently available to monitor and measure SOD. A panel discussion following the presentations identified the present strengths and weaknesses in the understanding of SOD processes and determined important areas for future investigation.
