The USAUS-H₂O diagram creator connects directly to the IAN symbol library database so that users can search for symbols by keywords, browse the albums, select from an IAN project symbol set (check out the USAUS-H2O set), or work from their lightbox collection. This allows students to quickly and easily develop diagrams detailing various issues with the water cycle in their area.

For more information, check out this blog post.

There is also a PDF of all symbols (regularly updated)
