OTIS En Español

OTIS - (One-dimensional transport with inflow and storage: 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.
