Abstract: An analytical model is developed for unidirectional-flow waterways in which the dissolved oxygen (DO) mass balance is dominated by reaeration and sediment oxygen demand (SOD) fluxes. To accurately represent the feedback ...

Abstract: A modeling framework that combines both two-dimensional (2D) and one-dimensional (1D) numerical models for the evaluation of organic-matter transport across the bed-water interface is presented. Emphasis is placed on ...

Abstract: Sediment oxygen demand (SOD) can be a significant oxygen sink in various types of water bodies, particularly slow-moving waters with substantial organic sediment accumulation. In most settings in which SOD is a concern, ...
