Conceptual Model: Main Channel and Storage Zone

OTIS: Conceptual model that includes the main channel and the storage zone.

Detailed Description

Depicts the processes that affect solute concentrations in the main channel and the storage zone. Within the main channel, solutes are transported downstream by advection and dispersion. Advection and dispersion are not included in the storage zone, where downstream transport is negligible. Lateral inflow represents additional water entering the main channel as overland flow, interflow, and ground-water discharge. Lateral outflow represents water discharging from the main channel to the surrounding watershed. The main channel and storage zone are linked through the process of transient storage; the exchange of solute mass between the main channel and the storage zone attributable to transient storage is modeled as a first-order mass transfer process. Chemical reactions occur within the main channel and the storage zone.
