AHS supports public understanding, education, and training in the science and technology of hydrology and water resources. An important part of our mission is promoting the responsible use, management, and preservation of water resources in the arid Southwest.
To support these goals, AHS funds meetings, scholarships, symposia, and other outreach and educational activities, mostly through its 501(c)(3) charitable arm, the AHS Foundation.
