Responsibilities

Performs hydrologic technician work in support of hydrologists, civil engineers, and other professionals engaged in scientific studies of surface water, meteorology, sediment and debris production, and water quality for water resource planning and design. Applies skills in mathematics, and the study of hydrology analysis and consideration of techniques and procedures, to perform the following duties:

• Collects, compiles and prepares various hydraulic data, in the form of tables or graphs, such as precipitation, stream flow, water quality, and reservoir storage, inflow, and outflow from published reports and responsible agencies.

• Uses topographic maps and construction plans to determine watershed drainage boundaries, flow paths, elevation area relationships, stream channel cross-sections, and basin hydrologic parameters. Uses longitude, latitude and other standard surveying descriptions to locate sites on map. Uses a planimeter to measure area. Transfers information from a map of one scale to a map of another scale

• Performs mathematical computations involving the use of algebra and geometry. Uses a calculator and mathematical tables and graphs in making calculations. Utilizes a knowledge of reproduction techniques in the preparation of complex or unusual plates, tables, and graphs for effective presentation of hydrologic information in reports.

• Performs field investigations accompanied by an engineer or hydrologist so as to become familiar with hydrologic characteristics of a study area. Locate water courses, stream gages, hydraulics structures, and drainage boundary divides. Measures channel cross sections and the physical characteristics of hydraulic structures.
