All workshops are capped at 30 participants. Workshops may be selected during registration for an additional cost of $50 and are limited to one workshop per person. Each workshop will take place during the time specified in the description on Monday, June 5 (between 1-5 PM).

W1. Working with Geospatial Hydrologic Data for Watershed Analyses in R and Python Using Web Services

• Leader(s): Marc Weber (EPA); Dave Blodgett (USGS); Mike Johnson (Lynker)
• Time: Monday, June 5, 1-4 PM
• This workshop will focus on a project-based overview of concepts and open-source tools for performing geospatial analyses with hydrologic data for watershed scale analysis using web services in R and Python. We’ll provide an overview of foundational spatial libraries in R and Python and examine and work with key hydrology-focused packages in R and Python. This will be a hands-on tutorial where we will work through a watershed-scale project demonstrating use of a handful of geospatial web services in both languages for conducting scientific studies.

W2. Integrating USDA-ARS and NEON Water Quality Data for Southeast Rivers

• Leader(s): Jim Coloso (Battelle, NEON Project); Oliva Pisani (USDA ARS)
• Time: Monday, June 5, 1-5 PM
• This workshop involves retrieving data from the STEWARDS database and NEON data portal. Participants will then use a combination of excel and R software to merge the datasets and compare water quality parameters at two nearby Georgia rivers, the Little River and Flint River. Spreadsheets and code used for the workshop will be available on GitHub for reference before and after the workshop.

W3. Introduction to the Water, Energy, and Biogeochemical Model (WEBMOD)

• Leader(s): Rick Webb (USGS)
• Time: Monday, June 5, 1-4 PM
• This half day workshop will demonstrate how WEBMOD simulates flows of water, major ions, stable isotopes, and temperature for a natural watershed draining the continental divide in Colorado and fields irrigated with water from the Yakima River in Washington. The course will be taught by Richard Webb, the principal developer of WEBMOD and author of the User’s Manual. Participants will be provided with background theory, software and input files and learn how to run the model in batch mode and within a Graphical User Interface.

W4. Tracer Techniques and the OTIS Solute Transport Model

• Leader(s): Rob Runkel (USGS)
• Time: Monday, June 5, 1-5 PM
• 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.  An additional 1 hour of instruction will include a step-by-step “how-to” on the use of OTIS to estimate transient storage parameters based on tracer data. This optional 1-hour extension is recommended for attendees who plan to implement OTIS within their research programs. Beginner to intermediate model users are encouraged to attend.
