GIS and Water Resources Modeling Workshop

Apparently this page is accessed by lots of people from all over the world (thanks to Google!). Despite providing these tutorials along with sample data, many are unable to process their own data and/or create reasonable models. Consequently, I get several requests to look at error messages and give advice. The most common error message is "Exceptional error - ArcMap is Closing". To help out some of these folks I decided to offer GIS and Water Resources Modeling workshop here at Purdue University, and it was a success! It is a three day workshop with first two days spent on learning and third day devoted to modeling using your own data. I plan to offer this workshop in the future so if you are interested, please send me an email.

Note: All tutorials have links for necessary datasets. If you have questions, send email to vmerwade_at_purdue.edu
