Answer to Question 1

Answer: Higher temperatures result in high evaporation rates. Also, the water table is lower in a desert, so there are significant losses to the water table.

Answer to Question 2

Answer: Both regions may have floods of similar magnitude, but the flood will crest more slowly in a humid environment. As a result, desert floods can erode large volumes of material in a short time. A humid environment will also have vegetation to anchor sediment and helping to hold it in place for longer.
