Hurricane Harvey's Effect on Soil Moisture
In this mini-lesson, students analyze soil moisture quantities associated with Hurricane Harvey around Houston, Texas on August 25, 2017.
Hurricane Harvey dropped record-breaking amounts of rainfall on August 25, 2017 in southeastern Texas. This includes the greater Houston region.
Note: Houston is the 4th largest city in the United States. Over a twenty-year span (1997 to 2016), this area added almost 1000 km2 of impervious surfaces (such as concrete, asphalt, etc.) to the landscape. This is almost 187,000 football fields of pavement, concrete, and buildings. (Source: Rice University)
