Final answer:
Riparian rights are for landowners adjacent to rivers or streams, while littoral rights are for landowners adjacent to lakes or seas, granting them certain privileges and responsibilities.
Step-by-step explanation:
In the context of property rights, riparian rights refer to the rights of a landowner whose property is adjacent to a body of water, such as a river or stream.
Littoral rights, on the other hand, refer to the rights of a landowner whose property is adjacent to a lake or sea.
Both riparian and littoral rights give the landowner certain privileges, such as access to the water, fishing rights, and the ability to construct docks or piers, but the specific rights and regulations may vary depending on the jurisdiction and the specific body of water.
