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 ...
This huge volume of water retreats at the start of the ebb tide in a surge. Later on during the ebb tide, water remains only in the creeks and the current is mainly a river (drainage) current and not tidal. Tidal creeks deposit sediment in a process called accretion, during the flood tide, which can maintain a flat plain by counteracting sea ...
Augusta wrote three books, two under a pseudonym. Her first, in 1895, was The Century Cook Book, as Mary Ronald.In 1901 The Century Company of New York published her seminal biology-research handbook The Sea-beach at Ebb Tide - A Guide to the Study of the Seaweeds and the Lower Animal Life Found between Tide-Marks.

Suisun Marsh, 116,000 acres (470 km 2) of land, bays, and sloughs, is one of the largest estuarine marshes in the western United States. Geologically, the Suisun Marsh is the product of water-borne sediment deposition, carried from the Sacramento and San Joaquin Rivers into the San Francisco Bay.
The name Dry Bay derives from the fact portions of the delta became dry at ebb tide and when river levels are low." [3] According to the U.S. Geological Survey's Geographic Names Information System, it was named in 1869 by the U.S. Coast Survey "because it appeared to be a shallow lagoon fed by silt-laden glacial streams."

It is hypothesized they enter pools during flood tides to feed and retreat to cover with ebb tides. [21] There are a range of fish species that can be found in anchialine pools and their presence usually indicates lower populations of hypogeal shrimp and an absence of epigeal shrimp. [20]
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.
