Question

The data in this map comes from the federal emergency management agency (FEMA). This data spans 18 years. Why would having 18 years of data be more helpful than having data for only one year

Answer 1

Weather can change from year to year. That means the flood risk level can also change yearly. Studying 18 years of data makes it possible to identify which areas are most prone to flooding. It provides a more accurate picture of where resources and funding for flood control would be most effective.anation - brittany
