Hydrologist basic education* requirements are listed below: Hydrology Series 1315 (opm.gov)

* Note the specific requirement for six semester hours each of calculus and physics. Calculus coursework must include differential and integral calculus.


Your application and resume must clearly show that you possess the experience requirements. Transcripts must be provided for qualifications based on education. Provide course descriptions as necessary.

Basic Requirement:
GS-1315 – Hydrology
Degree: Successful completion of a full 4-year course of study in an accredited college or university leading to a bachelor’s or higher degree that included a major field of study in physical or natural science, or engineering that included at least 30 semester hours in any combination of courses in hydrology, the physical sciences, geophysics, chemistry, engineering science, soils, mathematics, aquatic biology, atmospheric science, meteorology, geology, oceanography, or the management or conservation of water resources. The course work must have included at least 6 semester hours in calculus (including both differential and integral calculus), and at least 6 semester hours in physics. Calculus and physics, as described above, are requirements for all grade levels.
OR
Combination of education and experience — course work as shown above, plus appropriate experience or additional education. Acceptable experience must have included performance of scientific functions related to the study of water resources, based on and requiring a professional knowledge of related sciences and the consistent application of basic scientific principles to the solution of theoretical and practical hydrologic problems. 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.

In addition to meeting the basic requirement, you must also possess experience and/or directly related education in the amounts listed below.

Specialized Experience Requirement:

For the GS-11 level: One year of specialized experience equivalent to at least the GS-09 federal grade level. Qualifying specialized experience includes meeting one or more of the following: Collected, analyzed, and interpreted watershed data for input to environmental reports or assessment of stream condition; Used data to inform land management decisions or assess effects to all resources, i.e., physical and biological features; Applied conventional methods to analyze water samples and determine the causes of data anomalies; Prepared and carried out water quality monitoring programs, including preparation of plans, collection and analysis of samples, and interpretation of data, and reports.

For the GS-12 level: One year of specialized experience equivalent to at least the GS-11 federal grade level. Qualifying specialized experience includes meeting one or more of the following: Participated in hydrologic and soil productivity investigations and studies required for planning and design of multi-purpose projects; Compiled information from investigations and studies into long range prescriptions or plans for watershed management and/or water yield improvement; Reviewed completed watershed rehabilitation projects to determine their effectiveness; Participated in the land management planning process as required in the development of environmental assessments or environmental impact statements; Assisted in responding to environmental interrogatories by coordinating with technical experts in the preparation of responses and technical analyses.

Experience refers to paid and unpaid experience, including volunteer work done through National Service programs (e.g., Peace Corps, AmeriCorps) and other organizations (e.g., professional; philanthropic; religious; spiritual; community, student, social). Volunteer work helps build critical competencies, knowledge, and skills and can provide valuable training and experience that translates directly to paid employment. You will receive credit for all qualifying experience, including volunteer experience.

Work Experience:Your resume must clearly document the following for each block of work experience; the beginning day, month and year the work assignment started and ended; the hours worked per week; position title, and series and grade if applicable; and description of duties performed. This information must be provided for each permanent, temporary or seasonal appointment/work assignment or volunteer work and should be clearly documented as a separate block of time. Incomplete, inaccurate or conflicting work history may not be credited for qualifications purposes. This can result in an applicant not being considered for the position.

TIME IN GRADE REQUIREMENT: If you are a current federal employee in the General Schedule (GS) pay plan and applying for a promotion opportunity, you must meet time-in-grade (TIG) requirements of 52 weeks of service at the next lower grade level in the normal line of progression for the position being filled. This requirement must be met by the closing date of this announcement.
