Modern Water Cycle
For the first time in over 20 years, the U.S. Geological Survey (USGS) has released a new version of the water cycle diagram. The original USGS water cycle has been the basis for thousands of replica diagrams and a cornerstone of early-environmental education. The updated water cycle has quite a few changes, but the one that stands out the most, is the introduction of humans into the cycle. Up until now, the cycle has always been considered "natural" and humans have been treated as observers with little to no impact on the cycle itself.
Watershed Address
A watershed is the area of land that drains to a common creek or river. When it rains anywhere within a watershed boundary, water flows into the river and creeks and begins moving downstream. Knowing your location in the watershed and understanding what watersheds are upstream of you will help you understand your risk of flooding.
