The original purpose of AIH was to certify those individuals practicing as hydrologists. As the organization grew, other membership categories began to be recognized and included within the Bylaws of the organization. The first two certifications offered to hydrologists were for surface water and ground water/hydrogeology. Eventually a certification for water quality was added to complete the suite of sub-disciplines within hydrology. Any of the three certifications is open to individuals meeting the education and experience requirements, and who have successfully passed both the Fundamentals Examination and the Principles and Practice Examination. A certified member is entitled to purchase a stamp and embosser with their name and certification number. Also, a certified member may represent him/herself as either a Professional Hydrologist (PH) or Professional Hydrogeologist (PHG). Applications for hydrology certification are carefully reviewed by the Board of Registration and are finally approved by the Executive Committee.

Hydrologic Technician (certified)
After much deliberation among the AIH Executive Committee, the formation of a special committee to outline a program, and vetting by the academic, government and private sectors, the Hydrologic Technician certification was enacted within the organization in 2007. The program began with a charter membership period that brought qualified individuals into the organization to help build the program. Prospective certified hydrologic technicians can chose from one of three levels of certification that represents their level of experience and education. Qualifications for Hydrologic Technician certification is weighted heavily in favor of field method, hydrologic instrument, and data processing experience. While education for this certification is important, it is considered secondary to the hands-on knowledge gain through extensive field experience. AIH recognizes that the hydrologic technician's work is the foundation of all hydrologic application and interpretation; therefore, the organization considers it appropriate for this group to be included as hydrology professionals. Certified Hydrologic Technicians may represent themselves as HT I, HT II, or HTIII reflecting their level of certification. Applications for hydrology certification are carefully reviewed by the Board of Registration and are finally approved by the Executive Committee.
Annual Cost: $90
The Associate member is a category that includes individuals who have achieved a level of education that qualifies them to be certified, but do not meet the experience requirements. Associate members have neither taken any of the examinations for certification nor have their credentials been reviewed by the Board of Registration. An Associate member has all the same benefits as a certified member but cannot represent him/herself as either a certified Hydrologist or Hydrologic Technician. The purpose of this category is to give new practicing hydrologists and hydrologic technicians a point of entry in to the organization so they begin networking with cohorts and preparing themselves for certification.
Annual Cost: $35
Modeled after the very successful American Society of Civil Engineer entry-level program, the Hydrologist-In-Training (HIT) membership is for new college graduates who have passed the Fundamentals Examination. HIT members remain in status until they have met the required minimum years experience and have successfully passed the Principles and Practice Examination. An HIT member has all the same benefits as the other member categories; however, an HIT cannot represent him/herself as a certified Hydrologist.
Annual Cost: $100
The future of the American Institute of Hydrology relies on those who we train and mentor in the profession. Students enrolled in a full-time curriculum pursuing a degree in hydrology, earth sciences, and engineering may apply for this membership category. Student members have not taken the Fundamental Examination. More information about student membership and student chapters can be found at the student membership page.

A membership category that is specific to businesses, companies and other organizations that support the hydrologic sciences and industry. At least one individual within the prospective Corporate/Institutional category must be a certified member of AIH. Examples of Corporate/Institutional members can include engineering and environmental consulting firms, Universities, government agencies, hydrologic equipment manufacturers and vendors, laboratories, and other scientific organizations. The benefits of this membership category include free web-link advertising to the member's website, reduced cost on advertising and member notification of new hydrologic products and/or services, free posting of job announcements, and negotiated reduced cost for certifying new hydrologists and hydrologic technicians within their organization. Application for this membership category should be sent to the AIH Executive Director. The annual fee will be requested after review and approval of your application. Upon acceptance the Executive Director will contact your company regarding web services and other benefits.
Annual Cost: $250
A membership category that is nearly the same as the Corporate/Institutional with the exception that no member of the prospective organization has an AIH certified hydrologist or hydrologic technician. The benefits of this membership category include a web-link to the member's website , reduced cost on advertising and member notification of new hydrologic products and/or services, and free posting of hydrology related job announcements. Examples of this membership category may include equipment manufacturers and vendors that have an interest in communicating their products to the hydrologic community; engineering and environmental firms who are growing their presence in applied hydrology and wish to attract certified talent as well as advertise their services; and state and local government and non-government organizations that actively deal with water issues who wish to communicate their activities to the hydrologic community. Application for this membership category should be sent to the AIH Executive Director along with the annual fee. Following the processing of your application, the Executive Director will contact your company regarding web services and other benefits.
Annual Cost: $250
This is a category for members who have maintained active member status for 15 years and are now retired to an inactive status.
