The American Institute of Hydrology (AIH) was founded in 1981 to promote hydrology as a science and a profession and to help protect public interest and the profession from non-professional practices. It is the only nationwide organization that certifies the competence and ethical conduct of professionals in all fields of hydrology. The AIH Board of Registration, which consists of nationally recognized and respected scientists and professionals, thoroughly examine each applicant. The certification process is very demanding and surpasses many registration processes.
