... to evaluate the extreme influence of these three hydraulic loads exerting together on a drilling riser. Comparative analysis indicates that the maximal response of a riser emerges when the phase angles of SW and ISW are 12° and 0° respectively; around ISW trough, bending moment changes suddenly in a step-like...

Since the hydraulic flow is downward around the crest of sea waves and upward below the trough of sea waves, z is high (increases) below the crest and low (decrease) below the trough of the wave.
