Overlooking Revere Beach, the Ebb Tide soon became a "clubhouse" for members of the Patriarca family to socialize and plan crimes. In 1965, the Edward Deegan mob hit was organized there. By the late 1960s, the Ebb Tide had earned such a bad reputation that Castucci changed its name to The Beach Ball.
The Columbia Bar is a system of bars and shoals at the mouth of the Columbia River spanning the U.S. states of Oregon and Washington. It is one of the most dangerous bar crossings in the world, earning the nickname Graveyard of the Pacific. The bar is about 3 miles (5 km) wide and 6 miles (10 km) long. [1]
The water stops rising, reaching a local maximum called high tide. Sea level falls over several hours, revealing the intertidal zone; ebb tide. Oscillating currents produced by tides are known as tidal streams or tidal currents. The moment that the tidal current ceases is called slack water or slack tide. The tide then reverses direction and is ...
Waves have a double effect on mouth bar growth; while small and locally generated waves favor the bar formation by increasing the jet spreading, large, swell waves suppress bar development. [2] The complex effects of tides, on the other hand, depend on the relative strength of river inertia with respect to the tidal energy.
Wadden creek with exposed sandbar during an ebb tide. The littoral series of a flat coast starts in the permanently flooded shallow water region, or shoreface, with a sand or gravel reef (also called a bar). The longshore bar is an elongated ridge of sand found parallel to the shore in the surf zone on many flat coasts. It consists mainly of ...
Following low tide, visibility can be reduced as the ebb draws silt, mud, and other particulates with it. In areas with potentially dangerous tides and currents, it is standard practice for divers to plan a dive at slack times. For any vessel, a favourable flow will improve the vessel's speed over the bottom for a given speed in the water.
The exposure time can be much larger than the residence time if the water particles are leaving with the ebb tides and returning with the rising tide. The ratio between the number of water particles returning to the estuary and the number of water particles leaving is known as the return coefficient, r.
A tidal prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, [1] or the volume of water leaving an estuary at ebb tide. [2]The inter-tidal prism volume can be expressed by the relationship: P=H A, where H is the average tidal range and A is the average surface area of the basin. [3]
