Dakota can be used to answer questions such as:</br></br>* What are the important parameters in my model?</br>* How safe, robust, and reliable is my model?</br>* What parameter values best match my observational data?</br></br>Dakota has been installed on the CSDMS supercomputer, ''beach.colorado.edu'', and is available to all registered users. The full set of Dakota methods can be invoked from the command line on ''beach''; however, this requires detailed knowledge of Dakota, including how to set up a Dakota input file and how to pass parameters and responses between a model and Dakota. To make Dakota more accessible to the CSDMS community, a subset of its functionality has been configured to run through the CSDMS Web Modeling Tool (WMT; https://csdms.colorado.edu/wmt). WMT currently provides access to Dakota's vector, centered, and multidimensional parameter study methods.<br><br>In this clinic, we'll provide an overview of Dakota, then, through WMT, set up and perform a series of numerical experiments with Dakota on ''beach'', and evaluate the results.</br></br>Other material can be downloaded from: https://github.com/mdpiper/dakota-tutorial.<br>from: https://github.com/mdpiper/dakota-tutorial.<br>)
