Morphology
high-water + mark
The compound literally combines 'high' + 'water' + 'mark' so an English learner who knows the words can infer a point indicating the highest level reached. However, the computing sense is a metaphorical domain-specific extension (resource ceiling/threshold and triggering behaviour) beyond the literal image, so full technical meaning may not be predictable to a B1 learner without exposure.
Etymology
High-water mark in computing uses the same image of a visible line showing the top level that water reached. It names the 'maximum level' of a computer resource (like memory or disk) that a process reaches, just as the high-water mark shows the top point in a flood.
