갯벌에서 미세기(조수 간만)에 따라 바닷물이 흐르는 자연스런 물길에는 waterway=tidal_channel을 씁니다. 이러한 물길은 일반적으로 갯벌, 염습지 또는 맹그로브 숲 안에서 파도의 작용이 제한적이고 완만한 경사를 가진 보호된 해안을 따라 형성됩니다.

이러한 물길은 염분 농도가 높고 밀물 때 바다에서 멀어지는 물의 흐름이 썰물 때 바다로 향하는 물의 흐름과 같기 때문에 강과 구별할 수 있습니다.

Tidal channels are frequently found along coastlines with a gentle slope where the salt marsh, mangroves, or tidal flats are protected from wave action. In these areas, many branching channels may be found, which can appear to create networks similar to rivers and streams. However, these are not rivers: they usually contain salt water which flows away from the sea at high tide and towards the sea at low tide.

Some tidal channels connect to an estuary of a river and may be less salty than the sea, since the connect to the estuary. But in contrast to a river estuary, in a tidal channel the water flowing towards the sea at low tide is often slightly higher in salinity than the open sea water, due to evaporation, especially in mangroves and subtropical salt marshes. Unlike in a river estuary, the flow of water towards the sea at low tide is not significantly greater than the flow away from the sea at high tide in a tidal channel. By following the channel away from the sea, or observing the flow of water at low tide and high tide, it is apparent if the waterway is the estuary of a river, or a tidal channel.

Many tidal channels are currently mistagged as waterway=river, waterway=stream, natural=bay, or natural=water areas, and could be updated to this tag.

매핑 방법

• To map a tidal channel, make a simple linear way and add the waterway=tidal_channel tag to it. The direction of the way should be towards the sea (i.e. the direction of water flow at low tide).
• The centreline of a tidal channel should be outside of the coastline (natural=coastline), because this is a marine water body, below the high tide line.
• In mangroves, the natural=coastline is often drawn at the border of the open water at the ends of the tidal channel, but sometimes is drawn farther inland. In either case, the end of the mangroves should be drawn up to the edge of the open water in the tidal channel.
• In salt marshes and tidal mud flats, the borders of the tidal channel will still be outside of the coastline, but may be drawn as the outer limit of the natural=wetland.
• In tidal flats, tidal channels may only be visible at low tide. In these cases the tag should generally be reserved for named tidal channels, or those that are significant for navigation.

덧 태그

• name=* to specify the name of the tidal channel; for example, Big Creek.
• width=* to indicate the width of the channel in meters. This is an approximate average width of the channel throughout most of the length of that part of the waterway.
• salt=yes/no to indicate whether the water is salty.
• intermittent=yes to indicate the waterway is dry at low tide.

비슷한 지물

• For an artificial (man-made) small watercourse, see waterway=ditch and waterway=drain.
• For a wider man-made watercourse created for navigation use waterway=canal.
• If the waterway is a natural estuary with lower salinity than the sea and a significantly greater flow of water toward the sea than away, use waterway=river
  • (or waterway=stream if narrower than a few metres).
