Tide gauge data

The power-crossing section A-B during the storm can be evaluated from the current meter records from locations D and S and tide gauge data, but the quality of the data is not as high as that shown in Fig. 2 for two reasons. First, mechanical clocks were used in the current meters and interpolated corrections for their rates are required. Second, the available water level data are from a tide gauge within New Haven Harbor (rather than one at a current meter site), and a correction for the phase and amplitude difference of the tide between this location and that of the current meters is required. The tide height was corrected by a factor of...

Wind and density induced currents near the bottom temporarily are very weak. If there were no tidal currents, which are weak but are always ( ) present oxygen depletion in the near-bottom layers of the Baltic Sea probably would occur more frequently. Land uplift and subsidence play a major role in current studies of sea level rise. However, when evaluating gauge data, also the tides have to be taken into account, especially in historical datasets (Liebsch, 1997),... 

The water level data in Fig. 5 show that Ah at any place in the Sound (except at the extreme western end) is proportional to Ah at New London. Then, the analysis of water level deviations need be done only for the New London tide gauge. The hourly water levels at this station for the years 1938-1975 were obtained from the U.S. National Ocean Survey. The tidal component of the water level was removed by a regression... 

If it is available, historical information such as records of runup heights, tide gauge records and reports of observed tsunamis and the damage they caused should be used to assess the validity of the computational methods used for determining the near shore effects of tsunamis. The justification of the analytical methods presented for determining the probable maximum tsunamis should be supported to the extent possible by evidence of satisfactory agreement with data from observations, but in any case the results should be demonstrated to be conservative.

With the model approach described above, it has been possible, for the first time, to represent the tides in the entire B altic Sea, which could not be done using the measured water level data from coastal gauge stations. 

Ensure calibrated pressure gauges, 0—1, 380 kPa (0—200psig), are installed on the suction and discharge of each fire pump to be tested (record calibration dates on the flow performance data sheet, with +/—3% accuracy). For pumps taking suction lift, calculate the NPSH to the level of pump discharge. Offshore installation vertical turbine lift fire pumps require a calculation of the vertical head loss to the point of pressure reading, taking into account tide levels and seawater densities.
