HYDROLOGICAL TECHNICIAN

Hydrological technicians gather and record data on water levels, flow, and quality. They check readings of instruments that record rates of flow of water in streams and rivers. They record changing water levels of ponds, streams, and reservoir to chart changes in the water table, which is the depth in the ground where the soil becomes totally saturated with water. They examine water quality by physical inspection. They look for color and amount of sediment present through chemical analysis. They record all these things to monitor long-term changes. Other jobs hydrological technicians perform include studying precipitation, evaporation, run off, infiltration, and the capillarity of water. In all of these categories they study types, distribution, time, and area. They also record data on floods, population, and the chemical and physical properties of water. Sometimes they must figure out dimensions of a flood control damn. They may figure the safe and economical capacity of a reservoir. Also, they may figure correct spacing for irrigation to prevent erosion. Hydrological technicians must be knowledgeable about Hydrology, which is the study of movement and distribution of water on the earth. They must take courses in high school such as chemistry, physics, and math at least through geometry, and have language skills developed sufficiently to enable them to read technical manuals, and to write analytical reports on their findings. Usually some post high school prep classes are necessary. Types of classes include geology, physics, and laboratory practice. A hydrological technician earns roughly 25,000 dollars per year. Hydrological technology is only one of many jobs that this nation's river system provides for. Hydrological technicians play an important role in protecting rivers and putting them to use.
