Applications of OTEQ, OTIS, and Transient Storage

for Metals, Cations, and Acidic Streams

OTEQ is formed by coupling the solute transport model OTIS with a chemical equilibrium submodel. The submodel is based on MINTEQ, a model that calculates the distribution of inorganic species under the assumption of chemical equilibrium. The coupled model considers a variety of processes including advection, dispersion, transient storage, transport and deposition of water-borne solid phases, acid/base reactions, complexation, precipitation/dissolution, and sorption. Precipitated and sorbed species may reside within the water column or on the streambed; precipitated and sorbed species residing in the water column are subject to transport and settling. Total component concentrations are partitioned between dissolved, precipitated and sorbed phases based on equilibrium calculations for each computational stream segment.
