History
A concise historical narrative of NAICS Code 541690-85 covering global milestones and recent developments within the United States.
- Hydrology, the study of water and its movement in the environment, has been an important field of study for centuries. The ancient Greeks and Romans were among the first to study water resources and develop irrigation systems. In the 19th century, hydrology became a more formalized field of study with the development of new technologies such as the steam engine and the telegraph. In the United States, the establishment of the U.S. Geological Survey in 1879 marked a significant milestone in the development of hydrology as a scientific discipline. In recent years, the field of hydrology has seen significant advancements in technology, including the use of remote sensing and computer modeling to better understand and manage water resources.
