Morphology
The meaning is directly and transparently derived from combining 'tidal' (pertaining to tides) with 'stream' (a watercourse): a stream whose flow or level is affected by the tide. This adjective + noun composition follows a regular, cross-linguistic pattern and would be predictable to a B1 learner who knows both constituent words.
Etymology
The noun tidal stream comes from the simple picture of a stream being pushed and pulled by the tide, so the water moves forward and then back with each tide. So, the name means a part of a river where the 'flow' and 'direction' change because of the tide.
