Is a desert a topographic feature?

Why do flash floods and mudflows occur in deserts?

In the desert, storms can come on quickly, and because desert sands don’t readily soak up water, heavy rains can rapidly lead to flash floods. While rainfall over farmland can seep into the ground, sidewalks and pavement are impervious to moisture, causing heavy rains to run off to low spots very quickly.

Can deserts flood?

Defined by their aridity, rainfalls are rare in deserts. Desert sand does not easily absorb water, and many areas may only see a couple of inches of rainfall over multiple years. Therefore, heavy rains and irregular storms can trigger flash floods, which often follow the paths of dry stream channels.

How does flash flooding occur?

Flash floods occur within a few minutes or hours of excessive rainfall, a dam or levee failure, or a sudden release of water held by an ice jam. Most flash flooding is caused by slow-moving thunderstorms, thunderstorms repeatedly moving over the same area, or heavy rains from hurricanes and tropical storms.
