Mission Statement

The purpose of AIH is to enhance and strengthen the standing of hydrology as a science and a profession by:

  • Establishing standards and procedures to certify individuals qualified in surface-water, groundwater and water-quality hydrology.
  • Establishing and maintaining ethical standards to protect the public from irresponsible work.
  • Providing education and training in hydrology.
  • Providing the public and government advice and guidance concerning activities related to the hydrologic profession.


During the late 1970s and early 80s, a variety of regulatory and quality assurance requirements resulted in a great demand for services of hydrologists and hydrogeologists, a demand that could not be met by the existing number of professionals. Because of the concern that unqualified individuals would be hired to satisfy this demand, the need for certification of hydrologists and hydrogeologists was expressed repeatedly by individuals, consulting firms, and some state and federal agencies. For example, in 1979, an Ad Hoc Committee of the Association of University Watershed Scientists recommended strengthening of the U.S. Civil Service entry-level requirements for hydrologists. This effort was in response to professionals within the U.S. Forest Service and U.S. Bureau of Land Management who were concerned that the existing standards “did not ensure high-quality entry-level professionals in hydrology.”
