3)  urbanization ... meaning city life produces heat

I have more coming

6) Increase of temperature in a city due to heat absorption of buildings and roads 

still more coming....

7)  Long, sustained climate shifts .... climate does not shift in desert
8)  Increased chance for erosion ... sand blows away
9)  A population of people that live downstream .... rivers generally go upstream, so you would not do anything to it from the source; downstream
10) mining .... mining is nowhere near rivers

There you go, hope this helps! :D
