So, I'm coming up with a world in which, after a nuclear war in Africa, there is a bunker in the country of Chad. The landscape has been affected by over 50 atomic bombs. The main characters leave the bunker as the radioactivity has mostly worn off (after 100-something years), and I want them to discover a harsh, warped environment. What would the most extreme topographical effects of an atomic bomb be on a Saharan or Sahelian environment be?
- How would the landscape change? Would it flatten? Would it crack? Would it create strange landforms?
- How would the landscape's composition change? Would the sand turn to rock or glass?
- How would climate be effected? Would it become colder or hotter? Would precipitation levels change?
