A partly enclosed coastal body of water in which river water is mixed with seawater is called an estuary. An estuary is thus defined by salinity rather than geography. Many coastal features designated by other names are in fact estuaries (for instance, Chesapeake Bay). Some of the oldest continuous civilizations have flourished in estuarine environments (for example, the Tigris and Euphrates rivers, the Nile delta, and the Ganges delta).
âFederal crimesâ refer specifically to offenses that violate U.S. federal laws. They are investigated by federal law enforcement and prosecuted by United States attorneys in federal courts with federal judges.
There are federal violations that often are attached to credit card fraud. These appear under Title 18 USC 1029. If a thief pulls his stunt on government property across state lines, or against a government entity, then federal charges may apply. The consequences there are much worse â as in, 10 to 20 years in prison.
