An interdisciplinary team of physicists and geologists led by the University of Pennsylvania has made a major step toward predicting where and how large floods occur on river deltas and alluvial fans. In a laboratory, researchers created a miniature river delta that replicates flooding patterns seen in natural rivers, resulting in a mathematical model capable of aiding in the prediction of the next catastrophic flood. The results appear in the current issue of Geophysical Research Letters....

For many areas of the West, the Federal Emergency Management Agency's Flood Insurance Rate Maps (FIRMS) overestimate the amount of land area within the 100-year floodplain. New research suggests a way to improve the maps. The new three-pronged approach combines a new numerical computer model with two additional methods, satellite-image analysis and field observations. Each method serves as a check on the other two. The research team focused on the floodplains for a 10-year flood, a 100-year...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
