  • Association to a nationwide network of hydrologists
  • Access to and opportunities for contributing to AIH Bulletin
  • Access to career development and continuing education resources
  • Eligibility for annual awards


Unlike certification examinations for other organizations, AIH examinations focus solely on knowledge and understanding of hydrology.

President's Message

This is an overdue update to our AIH members and community about what your AIH leadership team has been up to this year. I am thrilled to announce completion of critical and timely updates to the governing documents for our organization – our AIH Articles of Incorporation (formerly, Constitution) and AIH Bylaws. We initiated the review and update process in 2016. Over the past six years, past and current AIH leadership team members devoted many, many hours to completing a comprehensive review and developing suggested revisions to these documents. This review and update provided a great opportunity to reflect on how we have operated and how we will function in the future. In the spirit of these changes, Leonardo Da Vinci once remarked (translated to English): “When you put your hand in a flowing stream, you touch the last that has gone before and the first of what is still to come.” It is extremely gratifying to see the results of our review/update process in our new governing documents, and I look forward to the next steps.
