		+	10.3.1 Current data (see S-4 –B-408)The term “current(s)” in this document is used to describe water movements which are generally constant in direction, and are not dependent on astronomical conditions (that is, are non-gravitational). A current is described by the direction towards which it is running. For tidal streams, see clauses10.2 and 10.5.
		+
		+	Currents occur as:
		+
		+	The flow of river water in rivers and estuaries;
		+
		+	Permanent flows in other restricted waters, for example İstanbul Boğazı (Bosporus);
		+
		+	Permanent or seasonal oceanic currents;
		+	Temporary wind-induced currents.
		+
		+	Only surface currents should be encoded. It is particularly important to depict currents (both the main flows and permanent eddies) which could set a vessel towards dangers.

(IHO Dictionary –S-32). Approximate tidal stream rates may be given as discrete rate values for flood and ebb flow during springs.  (S-57 Edition 3.1, Appendix A –Chapter 1, Page 1.173, November 2000).
