I know that when some rivers (such as the Nile) flow out to sea, they break up into several smaller channels. But I was wondering about the necessary features of the land and water for it to occur.

The reason why some rivers form a delta (Nile, Ganges, Mississippi, etc.) and some other form an estuary (Thames, Amazon, San Francisco Bay, etc.) is in the balance between sedimentary deposit from the river flow and sediment removal from the sea waters.
When this balance is positive (the river deposits faster than the sea can remove) a delta is formed, while when the sea removes faster than the river can deposit an estuary is formed.
On the sea side this is influenced mostly by tides and currents, while on the river side this is influenced by all the factor regulating the amount of transported sediments.
I.e. Nile has a delta, but since Aswan dam has been built, the amount of sediments transported to the sea has greatly decreased: in return this has resulted in the delta starting to be eroded by the Mediterranean sea.

Interesting. I live on an estuary (we just call it a river), so I've heard the term. But this is a nice clear explanation. I think you have a typo though. "the sea removes faster than the sea can deposit..." Do you mean "sea...river"?
