The American Institute of Hydrology (AIH) recognizes its members for outstanding accomplishments in the fields of groundwater, surface water, water quality, and institute development. These awards are named after prominent scientists and engineers, who have made numerous lasting contributions to the hydrologic sciences. AIH Awards include:

The Charles Vernon (C.V.) Theis Award was established in 1986 to recognize individuals who have made outstanding contributions in groundwater hydrology. Charles V. Theis graduated with a PhD from the University of Cincinnati in June 1929 and made numerous contributions to the field of groundwater science throughout his life. An excellent biography of C.V. Theis’ life and contribution to groundwater science is found online at

Nomination Criteria

The criteria for selecting an individual for an award includes, but is not limited to,

  1. A record of performance showing detailed scientific inquiries into water-related issues that are objective, credible, and useful — such as the integration of physical properties and chemical and biological processes.
  2. The record should show significant contribution to understanding how the hydrologic cycle affects humankind and how humankind affects the hydrologic cycle.
  3. The record should show the ability of hydrology professionals with multiple perspectives of water as a resource. Careful analyses and critical research are central, but guidance for making the value judgments that are necessary to choose among competing demands for limited resources is also important. Water users, hydrologists, watershed scientists, engineers, and resource managers must often make value judgments to decide among possible management actions.
  4. Award winners should be distinguished for their continued efforts to extend multidisciplinary approaches in the solutions of water problems.

Nomination Process

Each year, the AIH Executive Board will notify its members about the deadline for submitting nominations. 

The nomination packet for each award should contain the following:

  1. A formal nomination letter by the nominator, outlining the education, career, and a record of performance detailing accomplishments and noteworthy impact achieved by the potential candidate.
  2. A current resume of the nominee.
  3. A minimum of two and maximum of four supporting letters with a limit of three pages each.

The supporting letter writers should state briefly how they know the nominee and describe why the nominee is deserving of the award. Please submit your nomination to Award winners will be notified and the awards will be presented at an upcoming conference to be determined later in the year.

Award Vetting Process and Rules

  1. An ad-hoc awards committee will be established each year to evaluate the nominations and make a recommendation to the Executive Board.
  2. Upon review, deliberation and decision of the ad-hoc committee, at most a single candidate is selected for each award, and forwarded to the Executive Board for discussion and approval.
  3. Should the Executive Board approve the nomination, the President is responsible for contacting the selected person and informing them of the award. The President shall convey the time and venue for the award ceremony.
  4. The President cannot serve on this ad-hoc committee and is ineligible for any of the awards.
