How did the huang he differ from a river such as the nile?

1. the nile was made of yellow silt known as loess.
2. the nile was not depended on for daily survival.
3. the huang he did not cover a large portion of the country.
4. the huang he flooded without warning or predictability.

The way that the Huang He differed from a river such as the Nile is 4. the Huang He flooded without warning or predictability.
In the beginning, there was no way to predict whether this river was going to flood, whereas with the Nile and other rivers, it was pretty obvious and predictable. This is what makes the difference between these two rivers.
