One-Dimensional Transport with Inflow and Storage (OTIS): A Solute Transport Model for Streams and Rivers

OTIS is a mathematical simulation model used to characterize the fate and transport of water-borne solutes in streams and rivers.

The governing equation underlying the model is the advection-dispersion equation with additional terms to account for transient storage, lateral inflow, first-order decay, and sorption.
