Droughts to Floods: Mapping Extreme Weather
Extreme weather conditions
are happening this summer in the United States.
Severe drought is affecting the Southwest and West, while flooding is a
concern in the Midwest. The Ball State
University Libraries’ GIS Research and Map Collection (GRMC) on the second
floor of Bracken Library includes maps and atlases depicting historic weather
conditions, climate maps, and atlases of natural disasters.
The
New York Times has
published a set of interactive maps showing how the drought has affected water
use in California. Users can view maps showing the
changes in daily residential water use over the last two years: “Statewide, water use decreased 13.5 percent
during that period.” Maps showing the
size of proposed water usage cuts are available due to new mandatory
restrictions on water use. And maps
showing the daily gallons used per capita are also available.
The Indiana Department of
Natural Resources maintains an Indiana Floodplain Mapping page which includes the Indiana Floodplain Information Portal that provides an interactive
floodplain mapping tool, with specific address searching.
The GRMC includes flood
insurance studies and Flood Insurance Rate Map (FIRM) maps for cities and towns
in Indiana. Maps from the Indiana flood
Control and Water Resources Commission are also available in the GRMC.
Maps from the GRMC
circulate for two weeks or longer. For
more information about these cartographic resources, please contact the GRMC at
765-285-1097.
