Tracer techniques and solute transport models are frequently used to quantify the temporary detainment of solutes in hyporheic and surface storage zones. The physical process of "transient storage" has implications for a wide variety of constituents as the storage process affects residence time and the extent of biogeochemical processing. This 2-hour workshop provides an overview of the hydrologic processes underlying the OTIS solute transport model (One-dimensional Transport with Inflow and Storage), and how these processes are represented in the stream transport equations. Emphasis will be placed on fundamental concepts such as experimental design, data evaluation, and parameter estimation using tracer techniques. Beginner to intermediate model users are encouraged to attend. Additional information on OTIS is available at http://water.usgs.gov/software/OTIS/. The workshop will be presented by Rob Runkel, a Research Hydrologist from the U.S. Geological Survey. Please contact Rob at runkel@usgs.gov if you plan to attend the workshop.
Important note: Due to time constraints, the step-by-step OTIS example that was previously described on the EGU website will not be presented.
