Model My Watershed Release 1.21

Model My Watershed Release 1.21

Release 1.21 of the Model My Watershed web application was made public today!

MMW Release 1.21 prototypes a Data Search Portal with funding from the NSF-funded BiG CZ Data project. CLICK TO EXPAND.

We continue to pave the road for advanced features, with Release 1.21 focused on building a foundation for interoperability with other data and modeling platforms, while also including a pile of minor improvements and bug fixes.

Using the WikiWatershed platform, we launched the BiG CZ Data Portal to search an Area of Interest for datasets listings from three separate data catalogs (CINERGI, HydroShare, and CUAHSI Water Data Center). We developed this data search portal with separate funding from the National Science Foundation (NSF OAC award #1339834) with the goal to integrate diverse data from of biological and geological (BiG) disciplines for Critical Zone (CZ) science. Of most interest to WikiWatershed users is that we consider the BiG CZ Data Portal to be a precursor to the Monitor My Watershed workflow that we plan to launch within WikiWatershed in spring of 2018. Try it out at, and let us know what you think!

Release 1.22 also introduces a new public web-service Application Programming Interface (API). This modern REST API allows anyone to access nearly every function of Model My Watershed. CLICK TO EXPAND.

Developers will be most interested in our new public web-service Application Programming Interface (API). This modern REST API allows anyone to access nearly every function of Model My Watershed from their own custom scripts or software, written in Python, R or any other modern programming language. This API is our first step toward building two-way interoperability with HydroShare, an online collaborative environment for sharing hydrologic data and models that we will leverage for advanced sharing capabilities for Model My Watershed projects, BMPs and eventually monitoring data. Please explore our new API at, which allows you to try the service from a web browser, or read the RESTful Web Services: A Tutorial for more background. Note that to use our API, you will need to register for an account on the Model My Watershed web app at, and get your API Authorization Key/Token, which is available in the new My Account pages.

In Release 1.21 we also added a number of small improvements and fixed many bugs. Most prominent is our user profile page and updated new user registration forms. If you see a blue dot next to your user name, please add information to your profile!
