Slack water - Coastal Wiki
Slack water occurs twice during a tidal cycle. In coastal waters (flow influenced by friction and boundaries), one slack water occurs closer to low water (low-water slack tide, LWS) and another slack water occurs closer to high water (high-water slack tide, HWS). LWS marks the end of the ebb flow and the start of flood flow; HWS marks the end ...
