BASIC REQUIREMENT OR INDIVIDUAL OCCUPATIONAL REQUIREMENT:
Degree: 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

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.
Applicants with related experience in hydrology gained through earlier Federal Government employment might have gained that experience in one or more occupational series. Such series include Soil Conservation, GS-457; Forestry, GS-460; Soil Science, GS-470; Civil Engineering, GS-810; Chemistry, GS-1320; Meteorology, GS-1340; and Geology, GS-1350.
