Hydrology Education

 

Curious how hydrologists track rainfall patterns or monitor river levels? Want to learn more about what goes into river forecasts?

Hydrology is a complex science overlapping with many other sciences such as meteorology, geology, agronomy, and geography. Accurate river forecasts can't be made without accurate weather forecasts, for example. Learn more about the basics of hydrology such as the water cycle, monitoring current conditions, forecasting, and human impacts on hydrology, below.
