Sediment Spews from New England River After Irene

Sediment Spews from New England River After Irene | Developing Spatial Literacy |
Nearly a week after Hurricane Irene drenched New England with rainfall in late August 2011, the Connecticut River was spewing muddy sediment into Long Island Sound and wrecking the region's farmland just before harvest.


The effects of the flooding in Vermont and New Hampshire graphically manifested on the downstream parts of the watershed.  Good image for showing fluvial deposition and stream load.

Fantastic image, One thing that isn't mentioned is the potential effect that this will have an marine navigation. With such a massive movement of sediment, it's hard to imagine that there won't be deposits left throughout the Connecticut River and Long Island Sound. This can have a tremendous impact on boats traversing the waterways, when a foot of sediment can be the difference between safe passage and running aground.

Historical Tornado Data Visualized

Historical Tornado Data Visualized | Developing Spatial Literacy |

This strangely beautiful map shows every tornado to hit the U.S. between 1950 and 2011.  What physical geographic factors lead to this distribution?  What are the impacts of this data on human geography?

Def in agreement with John I'm wondering myself as to what the cause of the hole is. Id speculate it is due to some sort of terrain issues. maybe even man made structures.

the physical geographic factors that lead to the the distribution of tornadoes in the US is because the jet stream coming from the west and hot air from the Gulf of Mexio air both crashing together. This mostly happens in the Midwestern part of the country. Though there are times when supercell thunderstorms pop up in different parts of the country and can form tornadoes, such as the southern part of the US. The impacts of this data on human geography are can range from little damage to catastrophic causing billions of dollars in damage.
