Oxygen demand exerted by bed sediments of rivers, lakes and estuaries (SOD), which is due to the oxidation of settled organic matter, could often greatly affects their water quality.

Abstract
Oxygen demand exerted by bed sediments of rivers, lakes and estuaries (SOD), which is due to the oxidation of settled organic matter, could often greatly affects their water quality. Thus, a proper estimation of SOD amount is a relevant goal in dissolved oxygen balance modeling. However, SOD available modeling frameworks remain far from a complete understanding of complex phenomena involved. The paper proposes a dimensionless steady-state model of nitrogenous sediment oxygen demand (NSOD), where the solutions of mass balance equations for organic carbon and ammonium provide an useful estimation of system response. Moreover, a careful model parameterization allows to introduce some simplifications in the solution obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
