| - | Sedimentation in **lakes** is a sink for particulate phosphorus (PP) and organic nitrogen (ON), as well as for suspended sediments (SS), algae (AE), and silica in algae (AS). Sedimentation (//sed<sub>lake</sub>, kg/timestep//) is calculated as a function of concentration (//conc//) in the lake and lake area (//area, m<sup>2</sup>//). The sedimentation rate (//par<sub>sed</sub>, m/timestep//) is given by parameters (//sedon//, //sedpp//, //sedss//, //sedae//,//sedsi//) which are generic, but can be specified for each lake. The concentration used in the equation may be reduced (//lim, mg/L//) by general parameters (//limsedON//, //limsedPP//, //limsedSS//), but not for AE (//lim//=0). | + | Sedimentation in **lakes** is a sink for particulate phosphorus (PP) and organic nitrogen (ON), as well as for suspended sediments (SS), algae (AE), and silica in algae (AS).
