The following is illustrative of acceptable experience: field or laboratory work that would require application of hydrologic theory and related sciences such as geology, geo-chemistry, geophysics, or civil engineering to making observations, taking samples, operating instruments, assembling data from source materials, analyzing and interpreting data, and reporting findings orally and in writing. In some cases, professional scientific experience that is not clearly water resource experience may be acceptable if such experience was preceded by appropriate education in hydrology or by professional hydrology experience. SPECIALIZED EXPERIENCE I meet the basic requirement and I have 1 year of specialized experience that equipped me with the particular knowledge, skills and abilities to successfully perform the duties of this position. This experience is related to the work of the position and equivalent to at least the GS-12 grade level in the Federal service.

Additional selections may be made from this announcement if identical vacancies occur in the same location within 90 days from the closing date.

How to apply

If you are qualifying based on your education, you MUST provide transcripts or other documentation to support your educational claims. Unless otherwise stated: (1) official or unofficial transcripts are acceptable, or (2) you may submit a list with all of your courses, grades, semester, year, and credit for the course. All materials must be submitted by the closing date of the announcement. If more than 10 percent of your undergraduate course work (credit hours) were taken on a pass/fail basis, your claim of superior academic achievement must be based upon class standing or membership in an honor society. One academic year of graduate education is considered to be the number of credits hours your graduate school has determined to represent one academic year of full-time study. Such study may have been performed on a full-time or part-time basis. If you cannot obtain your graduate school's definition of one year of graduate study, 18 semester hours (or 27 quarter hours) should be considered as satisfying the requirement for one year of full-time graduate study. If you are using education completed in foreign colleges or universities to meet the qualification requirements, you must send a Certificate of Foreign Equivalency with your transcript in order to receive credit for that education which shows the education credentials have been evaluated by a private organization that specializes in interpretation of foreign education programs and such education has been deemed equivalent to that gained in an accredited U.S. education program; or full credit has been given for the courses at a U.S. accredited college or university.
