| - | flat shorelines usually absorb most wave energy while steep shorelines and barriers in the water can cause waves to bounce off and rebound with the rebounding waves working at odd angles to the prevailing wave patterns and causing greater turbulence. This can create more challenging paddling. It also can contradict the usual wisdom of staying closer to shore for safety or easier paddling when rebound makes for more difficult paddling conditions closer to shore. Transient rebound can quickly cause more turbulence when larger waves from passing boats or ships bounce off of the shore. Abrupt barriers in the water can cause pronounced rebound referred to as "[[https://en.wikipedia.org/wiki/Clapotis|clapotis]]". If a steep shoreline is shallow enough to expose flat shore at lower tide levels then wave energy will be better absorbed and rebound can be mitigated during lower tide. | + | flat shorelines usually absorb most wave energy while steep shorelines and barriers in the water can cause waves to bounce off and rebound with the rebounding waves working at odd angles to the prevailing wave patterns and causing greater turbulence.

| - | If you have access to a shipping channel or some water where there is large boat or ship traffic, be aware of the interaction between water depth and boat wakes (refer to "breaking waves" above) and where it is better to position yourself. Shallower water can cause boat wakes (like all waves) to steepen and possibly break. This may be good for surfing where it allows you to more easily catch boat wakes (particularly from smaller boats) if they get somewhat bigger and steeper, or it can make already good size wakes too big, too steep, breaking, and more dangerous than you want to deal with. | ||
