21. In general, any saltwater intrusion into the hapua will only occur during a storm via wave overtopping or sea spray. 22. Large overtopping flows are still a problem, as they can scour the foundations if not accounted for in the design. 23. Others collapsed after a brief period of overtopping ( Industrial Canal ) caused scouring or erosion of the earthen levee walls. 24. The potential overtopping gave rise to sensational stories in Denver newspapers and caused annual nervousness in Pick Sloan Missouri Basin Project. 25. To accommodate overtopping , a single layer of 30t dolosse units was placed along the leeward side of the main breakwater. 26. The storm brought considerable damage to the Seaview Caravan and Chalet Park in Swalecliffe due to overtopping of the sea defences. 27. Overtopping devices are long structures that use wave velocity to fill a reservoir to a greater water level than the surrounding ocean.28. Others collapsed after a brief period of overtopping ( Industrial Canal ) caused scouring or erosion of the earthen levee walls. 29. No spillway was provided; instead, the dam was designed to withstand overtopping of of water pouring directly over its crest. 30. Even a small sustained overtopping flow can remove thousands of tons of overburden soil from the mass of the dam within hours.
