Fortran Program for Estimating Stream Transit Losses of Reusable Water, El Paso and Pueblo Counties, Colorado

The transit-loss accounting program, which has been in continuous daily use in some form since April 1989, has provided water-rights administrators with a tool to effectively manage RRFs and administer water diversion priorities along Fountain Creek on a daily basis.

One-Dimensional Transport with Equilibrium Chemistry (OTEQ): A Reactive Transport Model for Streams and Rivers

OTEQ is a mathematical simulation model used to characterize the fate and transport of waterborne solutes in streams and rivers. The model is formed by coupling a solute transport model with a chemical equilibrium submodel. The solute transport model is based on OTIS, a model that considers the physical processes of advection...

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.
