Gunston Cove is an inlet of the Potomac River, at the confluence of Accotink Creek and Pohick Creek in Northern Virginia.The Cove forms the northern boundary of Mason Neck, once home to the revolutionary hero George Mason and now site of several regional parks and the Mason Neck National Wildlife Refuge.
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
Mason Neck is a peninsula jutting into the Potomac River in Fairfax County, Virginia, southwest of Washington, D.C..It is surrounded by Belmont Bay to the west, the Potomac River to the south and east, Gunston Cove to the northeast, and Pohick Bay to the north-northeast.
SR 242 heads southeast as a two-lane undivided road through a forested area with scattered residences on Mason Neck, a peninsula that fronts the Potomac River between Belmont Bay and the mouth of the Occoquan River to the west and Gunston Cove, a bay formed by the confluence of Pohick Creek and Accotink Creek, to the east.
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
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 ...
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
The semi-diurnal tides go through one full cycle (a high and low tide) about once every 12 hours and one full cycle of maximum height (a spring and neap tide) about once every 14 days. The semi-diurnal tide (one maximum every 12 or so hours) is primarily lunar (only S 2 is purely solar) and gives rise to sectorial (or sectoral) deformations ...
