Abstract

This paper gives a summary and assessment of eight methods used by various researchers for estimating the sediment oxygen demand (SOD) rate. Part 1 defines the SOD rate and its importance in water pollution control studies. Part 2 discusses the in-stream processes that affect the SOD rate and thus complicate efforts to accurately measure the SOD rate. Part 3 reviews the eight methods used for estimating SOD rates in water quality modeling studies and compares the methods in terms of their precision, time requirements, and training requirements (ease-of-use). Part 4 suggests a logical procedure for determining the appropriate measurement precision and budget for SOD data collection. These precision and budget specifications can guide the selection of an appropriate method for measuring SOD rates for a particular water quality modeling study.
