A top priority for today's science advisor should be Alternative Energy, with a fleet of Think Again Tanks to reconsider the potential of cold fusion, hydrogen cells, more efficient solar power, better methods of drilling for methane, and employing wind and tidal energy. [1] Numerical simulations of the Hudson River estuary using a terrain‐following, three‐dimensional model (Regional Ocean Modeling System (ROMS)) are compared with an extensive set of time series and spatially resolved measurements over a 43 day period with large variations in tidal forcing and river discharge. The model is particularly effective at reproducing the observed .

Recent numerical experiments with high horizontal resolution (grid spacing of 25km or less) have suggested that the impact of the Gulf Stream on the “storm track” is mediated by the frontal circulation embedded in extra-tropical cyclones. In a series of controlled experiments with the UK Met Office Model, we were able to show that. The channel analysis and design evaluation tool (CADET) is a numerical program to determine the optimum dredge depth for the offshore portions of entrance channels.A brief description of the theoretical basis and risk assessment in CADET is presented. Validation comparisons between CADET predictions and field measurements of wave-induced vertical motions at Ambrose .

  Indeed certain regions near the Gulf Stream and in the Equatorial Countercurrent have a marked downscale transfer. Nevertheless, on average an upscale transfer is a reasonable mean description of the extratropical energy scale transfer over regions of O (10 3) km in by: The Persian Gulf is a marginal sea in a typical dry zone and is an extension of the Indian Ocean. It is located between the longitude of ° E and the latitude of 24–30° N (Fig. 1). This inland sea is connected to the Gulf of Oman in the East by the Strait of Hormuz. The gulf includes an area of km2. It is km long and its width.

At this location variability in the zonal velocity, within and across different seasons, is largely influenced by generation and propagation of long waves (Fu ; Iskandar and McPhaden ).The southern site 2 is located near the eastern edge of the thermocline ridge and the flow of currents here is Cited by: 4.

the mean axis of the Gulf Stream moves to the south, and the northward overshooting of the Gulf Stream separa-tion is reduced when the input boundary transport of their model DWBC at 45°N was increased.

Ezer and Mellor () showed that the NCG north of the Gulf Stream is necessary to Gulf Stream separation at Cape Hatteras. The sea level unit is in meter relative to the average inand the Gulf Stream gradient anomaly unit is in meter elevation change per km relative to m/ km.

Various lines of evidence suggest that Gulf Stream heat transport profoundly influences the climate of the entire Northern Hemisphere and, thus. averages about every 8 to 9 months (Leben, ).There is some evidence of a higher probability of separation during the spring and fall (Hall and Leben, ), but there is notable variability in the timing of terms of mechanisms, Sturges et al.

Three large sedimentary basins exist within the gulf. The northern edge of the Gulf of Elat, the Gulf's Head, forms the divide between the northern sedimentary basin of the gulf, the Elat Deep basin, and the on-land sedimentary basins of the southern Arava by: Next, the book covers the numerical methods for the solution of the equations of tidal dynamics.

The Mississippi river is the seventh largest river globally in terms of its sediment flux (Meade and Moody,Allison et al., ), where it delivers ∼ Mt of sediments per year to the northern Gulf of Mexico (nGoM).The combined high fluvial sediment discharge, relatively steady sea level, and modest wave and tide energy have resulted in the relatively Cited by: 2.
