Nomination process
The Hydrology Section has adopted a two-round process for its Section Awards to allow a more flexible, open and efficient development of the Section’s talent pool. The first round of nominations requires only a letter from the lead nominator, the nominee’s CV and optionally, a Selected Bibliography. The Langbein lecture committee will review the first round nominations and request full nomination packages from a select number of applicants (nominally 5) for further consideration. The procedures and requirements for both first and second round packages are outlined below:
First Round nomination packages must be submitted through the online platform and received no later than midnight, EST, 28 February 2023.
First Round Requirements:
- Nomination letter, no more than two pages in length, stressing the nominee’s qualifications to meet the selection criteria and qualifications as stated in the award description. The nomination letter must also list at least three potential writers of letters of support.
- The nominee’s CV, no more than two pages in length, and containing the following information as a minimum: CVs must list all the following candidate information: name, mailing and email address, history of employment, degrees, research experience, honors, memberships, service to the community through committee work, advisory boards, etc.
- A Selected Bibliography, no more than two pages in length, may be included in the first round nomination package, but is not required for first round consideration. The Selected Bibliography should briefly state the total number and types of publications; specify the number published in AGU publications. For example: “Jane Doe is the author of 92 publications, 86 in peer-reviewed scientific journals, 14 of which have been published in AGU journals and books. The following selected list best supports Jane’s nomination for AGU Fellow.”
Second round notifications to all nominators will occur around mid-to-late March 2023. Nomination materials for the second round must be submitted through the online platform.
Second Round Requirements
- The nomination letter may be up to two pages in length and should stress the nominee’s qualifications to meet the selection criteria and qualifications. The nomination letter should clearly document the contributions to the science of hydrology, education, or societal impacts at an early stage in their careers.

The Selected Bibliography should briefly state the total number and types of publications; specify the number published in AGU publications.
