Indian Floods

A while back I published a lesson plan showing the causes and effects of global warming on flooding in the Brahmaputra. Unfortunately the discussion was all to accurate and floods have been occurring in the region I discussed in the last month or so. Google have published their own Google Earth project showing imagery from August 3oth and 1st of September.

Here is a screenshot from my lesson plan:
this image shows settlements in the area, the color of the circle shows how 'sensitive' they are to flooding and the size the population.
this image shows the same area with a red overlay of what has been flooded from the google project. The two translucent areas show regions I identified in the lesson plan as;
  • North area: poor people living close to the river
  • South area: richer people living further from the river.
Design Point: The red color used is far too intense and isn't a natural 'water' color - dark purple or blue would have been a better choice. At the moment 'river of blood' is what springs to my mind.
