What is Hydrologic Warning?


The phrase "hydrologic warning" is not commonplace, but it has a broad, diverse meaning to those familiar with it.

Hydrologic Warning is the ability to warn of imminent danger to life, property, and the environment from hydrologic disasters through the use of automated remote data collection networks, modeling and analyses, and integrated hazard communication.
