Talk:Proposed features/sluice gate
Needed, but ...
this proposal takes a too narrow view. As you see in the Wikipedia, there is much more to cover with this feature - not only „in agricultural areas“, not only used for irrigation. --nkbre 00:12, 10 January 2011 (UTC)
I don't really think, that this change will do enaugh. The description has to be more general. For example:
A sluice gate is a facility to control water levels and flow rates of waterways. Sluice gates are commonly used for controlled irrigation and drainage of agricultural or other areas. They can be part of the flood protection system. In some cases, sluice gates are in pairs with one on either side of a dike. (see wikipedia:Sluice, wikipedia:de:)

Another type of gate which somehow needs to be covered by this proposal: a flood gate which is built into a dyke, often to make it possible to have a road going through a dyke.

Yes, there is a tag needed. But wikipedia:Coupure doesn't fit here. Because sluice_gate is a part of waterway and what you mean is a highway crossing a gate in a man_made=dyke. Water shouldn't flow here - never.

There are seamark:gate:category=sluice with seamark:type=gate and seamark:gate:category=dyke with seamark:type=gate based on IHO Datamodel (International Hydrographic Organization). For further information see https://wiki.openstreetmap.org/wiki/Seamarks/Gates .
What about floodgates?
In https://en.wikipedia.org/wiki/Floodgate we have that a floodgate "may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system"
What exactly is the difference from a sluice gate and a floodgate?
Right now flow_control is slightly more used than floodgate (205 vs 167 objects)
