I came across the sentence like
"The ship began to move gently down the river with the out-running tide".
I checked "out-running tide" in dictionary but I can't find them. Could you teach me?

The out-running tide is tide which is running out. The participle-phrase can be turned into an adjective, but when that happens, the preposition, here out, is moved to the head:
When the tide is running out we can call it the out-running tide.
You won't necessarily find in a dictionary every adjective which can be formed in this manner.
Although it would be grammatical to transform almost any such phrase in this manner, if native speakers as a group don't tend to do so, the transformation would sound a little odd, or perhaps "literary". Here's an example:
His baggy trousers were slipping down.
He tightened his belt because he was wearing baggy down-slipping trousers.
