Two things stick out for me:

1. You propose to map all streams with "intermittent=yes". I am not
familiar with Tenerify hydrography but is it really correct that they
are all subject to drying out?

2. You propose to import the original object ID as "ref:pht". At the
same time you say you're not envisaging any later updates. Keeping an
external ID can often be an impediment for mappers working with the data
later: Imagine you want to merge two streams and your editor asks you:
"should the resulting stream have ref:pht=123 or ref:pht=234"? That
would certainly confuse you. Or if you split a stream and you wonder if
it is ok that you are now breaking the presumed 1:1 relationship to the
original data. -- I would recommend to include ref:pht only if the
assumed good use of that is much bigger than the potential issues. You
write that the ref:pht could "be used to locate the stream in the
location map", but when the stream is mapped in OSM then it should be
easy to locate it on any map!
