AGU Hydrology Section Standing, Technical & Advisory Committees

The Hydrology section has a very active group of technical and standing committees, which is where much of the planning for section activities takes place. The wide range of activities offered by the section is due in large part to the work of the many dedicated committee chairs and members. Technical committees initiate most of the section’s special sessions at AGU meetings. For information on the work of a committee, how to make suggestions for special sessions, or how to join a committee, contact the committee chair.
