The tidal prism method is simple and easy to apply.

Therefore, flushing times of sewage waters of Karachi harbor and Gizri creek are calculated by modified tidal prism method [22, 23] and freshwater fraction method [20, 24].

Among specific topics are the flushing of Louisiana's coastal bays under hurricane conditions, Puget Sound Operational Forecast System as a real-time predictive tool for marine resource management and emergency responses, overland tidal power generation using a modular tidal prism, and coupling a high resolution hurricane storm surge model to operational weather and ocean predictive systems.

Estuarine and coastal modeling; proceedings

Tide restrictions reduce the tidal prism and thereby limit seawater flushing and dilution of constituents delivered to the estuary in discharging freshwater; this dilution is reduced both landward and seaward of the restricting structure.

Effects of tidal restrictions and potential benefits of tidal restoration on fecal coliform and shellfish-water quality

Highest densities were measured at sites immediately upstream of the tidal prism, and at the head of the open channel where it daylights, with geometric mean densities (MPN/100 ml) ranging from [10.sup.2]-[10.sup.3] for E.

This is approximately 0.045% of the tidal prism of an average tide.

Tides and their seminal impact on the geology, geography, history, and socio-economics of the Bay of Fundy, eastern Canada

Reconfiguration of the south jetty (completed in 1991) and dredging of a 91-m wide, 3-m deep inlet channel in 1992 improved inlet and channel stability and increased the tidal prism to that observed in the 1930s.

This situation restricts the tidal prism so that during the dry season (May through October) the mouth of the lagoon remains blocked by sand, preventing tidal exchange.

Also, on the other hand, the damming of large areas of marshland for fish-farming has contributed to a sharp decrease of the tidal prism.

Efectos antropicos en la morfodinamica de la costa de Huelva (SO Espana)

Because tides are variable in strength, the tidal prism and tidal volume in an estuary are also variable as is the wet cross-sectional area, which is that part of the total cross-sectional area filled with water.

Tides and their seminal impact on the geology, geography, history, and socio-economics of the Bay of Fundy, eastern Canada

However, total tidal range and the tidal prism are reduced due to a cobble sill at the inlet (Hubbard 1996).
