<br>
Following from the discussion on "Seasonal, intermittent, and
ephemeral water tags" I have created this proposal.<br>
<br>
<br>
Hopefully the definition is tight enough that it excludes
intermittent, seasonal and any other thing that is not
ephemeral.<br>
<br>
I have also included a guide on determination so that mappers
can see how to determine if something is ephemeral.<br>
<br>
<br>
So here it is ...<br>
<br>
<a

<br>
<br>
Is it clear? Do you understand it?<br>

<p>No, "ephemeral=summer" is unclear -</p>

<br>
It is a possible ephemeral flow (a flow of short duration) ... that
can only occur in summer.<br>
<br>
Similar to a tag seasonal=summer ... something that is seasonal that
can only occur in summer.<br>
<br>
I quote from the seasonal OSM wiki page <br>
"describes exact season (if possible) when feature is present." <br>
<br>
I'll put simillar on the proposed ephemeral page too, see below. <br>
<br>
<br>
<blockquote type="cite" cite="mid:LD8jaOQ--3-0@tutanota.com">
<p> is it <br>
</p>
<p>for flow that is constant but ephemeral</p>
</blockquote>
<br>
An ephemeral flow is of short duration. <br>
A constant flow would be there all the time ... so it could never be
described as ephemeral. <br>
<br>
-------------------<br>
The tagging text on the ephemeral page now reads <br>
"If a season is specified it states the exact season (if possible)
when the ephemeral can occur, during other seasons there would be no
ephemeral flow. <br>
<br>
For example, when tagged ephemeral=summer the ephemeral flow can
only take place in summer, thus the ephemeral flow is restricted to
one season." <br>
<br>
Is that clear? <br>
<br>
------------------------------------<br>
Note that ephemeral=yes does not mean that a flow will occur every
year. <br>
It only says that any flow will be of short duration and will be dry
most of the time. <br>
