“…Figure 19 shows the increasing tide elevation at Bayshore as spring tide is approached (smoothed by a 7-day running average). The large bumps in the curve occur about every 2 weeks during spring tides (the general rising trend of this ciirve is associated with the annual cycle of sea level increase until autumn (Harris 1981) be related to the limitation of ebb flow discharge through the channel during spring tides. Friction effects on maximum ebb flow limit the amount of water that can leave the bay.…”

ABSTRACT:The objective of this monitoring at Bamegat Inlet was to determine the response of the inlet system to a new south jetty completed in 1991 that essentially parallels the existing north jetty. Bamegat Inlet is accessed by a large number of commercial, sport fishing, and recreational vessels each year. An unstable navigation channel and numerous accidents and deaths at Bamegat Inlet led to the constmction of the new south jetty. The response of the new south jetty and inlet system was determined by data collection and monitoring and compared with design predictions, lliis new knowledge will contribute to improved jetty and inlet system design guidance, enhance construction of rabble-mound jetties, and develop better maintenance techniques for tidal inlets. The monitoring plan evaluated four fundamental hypotheses of the project design objectives: (a) the new south jetty and new channel alignment will not adversely affect tidal hydraulic response or high tide level in the inlet by system (i.e., no flooding problem), and prototype hydraulic response will be as predicted by a previous physical model evaluation; (b) the new south jetty realignment will improve navigation safety by stabilizing the navigation channel and depth between the jetties and over the outer bar (ebb tidal shoal), and will eliminate dredging in these regions; (c) flie new south jetty will be stracturally stable; and (d) the jetty system realignment will not adversely affect upcoast or downcoast beaches.

“…The annual maximum and minimum water levels without astronomical tides, namely the annual maxima (or minima) dataset shall be used to predict the extreme water levels at different return periods using probability distribution functions. The effects of astronomical tides on the predicted extreme water levels are retained by using a joint probability of both surge and tide (Harris 1981), which is considered to be conservative (CEM 2002).…”

The paper presents comprehensive statistical analyses of winds and water levels in Mobile Bay, Alabama, based on long-term meteorological and tidal observations at several locations. A procedure has been developed to select the most probable parent distribution function from a list of candidate distributions. The theoretical functions that fit the data best enable us to predict the extreme values of winds and water levels at different return periods. We have demonstrated the importance of dividing the winds into hurricane and nonhurricane seasons and separating astronomical tides from weather-driven water level changes. The statistical analysis suggests that the wind speed averaged over 8 min at Dauphin Island, Alabama, at the 100-year return period would be 48.9 m/s, which is equivalent to a sustained 1-min wind of 205 km/h, a very strong category 3 hurricane on the SaffirSimpson scale. The probability distribution models predict that the 100-year maximum water level would be 3.23 m above the mean lower low water (MLLW) level at the bay entrance and 3.41 m above the MLLW level near the head of the bay, respectively. Extremely low water levels important to navigation are also found. Application of the predicted extreme winds and surges is illustrated through the development of a storm wave atlas in the estuary. It is expected that the methodology and results presented in this paper will benefit the management and preservation of the ecosystems and habitats in Mobile Bay.

Bending effects on Nb 3 Sn wires have been investigated to understand the critical current degradation of large Nb 3 Sn superconducting cables. An integrated model taking into account the neutral axis shift, the current transfer length, the mechanical filament breakage and the uniaxial strain release due to applying bending has been developed for a Nb 3 Sn wire. Five different Nb 3 Sn wires developed by the ITER parties were tested. The experimental data are presented and analyzed with a newly developed integrated model. The current transfer effect appears to be an important factor.
