|
 | A modified version of Professor W. Hansen's (l966) numerical hydrodynamical prediction model is used to predict typical tide and tidal current variations in the South China Sea for five different wind fields. Cotidal charts constructed from the sum of the major partial tides are presented for higher high and lower low water. The model, basic assumptions and boundary conditions are presented. No statistical evaluation of the model results can be ... |

|
| Predicted tidal corrections are used primarily in reducing soundings (entered on the work sheet) to an approximate common tidal plane, prior to obtaining observed tidal corrections (used on the final sheet). In the event tidal observations are not feasible, as with surveys of limited extent and where time does not permit, it becomes necessary to use predicted corrections for the reductions of soundings to be entered on the final sheet. ... |

|
| A hydrographic survey of Block Island was made on August 17th to 19th on board the R/V UCONN and the CONRAD, JR. The two ships made several runs of two triangular circuits of stations, measuring temperature and salinity at all stations. The change of temperature and salinity due to tides reaches maximum at the deep layer in the center of the southern channel. The water of low temperature and low ... |

| TIDE LEVEL AND BOTTOM FRICTION EFFECTS ON WAVE REFRACTION AS DETERMINED BY NUMERICAL WAVE REFRACTION PROCEDURES. |

|
| Numerical wave refraction programs permit a detailed study of the transformation of wave energy as waves move from deep water to shallow water. By eliminating the subjectivity that is present with hand drawn diagrams the effect of small variations in the initial assumptions and wave conditions can be investigated. The effects on wave refraction of tide level changes and bottom friction are investigated here. It is demonstrated that a uniform ... |

| NON-LINEAR WAVE EFFECTS ON TIDE GAGES. |
MAY 1967 |

| Authors:

|
| For tide stations at locations subject to moderate or high waves, the damping device is not linear, since the flow through the orifice is approximately proportional to the square root of the differential head. The purpose of this paper is to investigate the non-linear interaction between this filter and second-order wave theory, specifically estimating the effect of this interaction on the water level inside the stilling well for a variety ... |

|
| Simultaneous measurements by Eulerian and Lagrangian methods were made continuously between 30 July and 5 August 1962. The survey zone extended southward along the shore 11.5 km (7.2 mi.) from the Cape Henry Light and offshore for a distance of 1.4 km (0.87 mi.). Three Roberts Radio Current Meter Stations were established along the seaward margin of the zone; five stations were established on shore for longshore-current and wave measurements. ... |
