Selecting Terminal Water Surface Elevations

Journal of Hydraulic Engineering, 1986
The U.S. Army Corps of Engineers, San Francisco District has developed an annual maximum tide stage versus frequency relationship for water surface elevations observed since 1855 at the Presidio, San Francisco Bay. The results have been extrapolated to 50 locations in San Francisco Bay. Corte Madera Creek is a tributary to San Francisco Bay.

Effects of discontinuous submerged breakwater on water surface elevation

Ocean Systems Engineering, 2015
Submerged breakwaters are used to prevent shore line erosion and sediment transportation. One of their advantages is low visual impact. In this paper, the effects of discontinuous submerged breakwaters over water surface elevation was numerically studied considering the extended Boussinesq equations as governing equations using MIKE21 software.

Maximizing Multi‐Decadal Water Surface Elevation Estimates With Landsat Imagery and Elevation/Bathymetry Datasets

Water Resources Research, 2022
AbstractIdentifying patterns and trends in long‐term lake dynamics is essential to establish effective water management procedures and boost our understanding of inland water's role in the global water cycle. This research leverages Google Earth Engine to estimate multi‐decadal water surface elevations for 52 lakes and reservoirs with varying physical ...

Measurement of Ruffled Water Surface Elevation

Journal of the Hydraulics Division, 1965
A probe is described for the measurement of the mean level of a ruffled water surface in a laboratory. In principle the instrument is a probe that measures down from a reference datum by counting increments of 0.001 in. until it makes contact with the water surface.

Distribution of sea-surface elevations in intermediate and shallow water depths

Coastal Engineering, 2020
Abstract Waveforms described by the second-order Stokes-type approximations are prone to display anomalous troughs with spurious negative crests. The systemic occurrence of such physically unrealistic features restricts the range of relative validity of second-order models and causes serious errors in modeling the statistics of sea-surface elevations,

Effect of water at elevated temperatures on the wool fibre surface

Surface and Interface Analysis, 1999
Aqueous treatments are found in many stages of wool processing. Water and heat are known to alter the chemical nature of the whole fibre. There is an incomplete understanding of the full effects of aqueous treatments on the fibre surface. This study investigates changes to the fibre surface as a result of exposure to water at elevated temperatures ...

Shallow Water Surface Wave Elevation Distributions

Journal of the Waterway, Port, Coastal and Ocean Division, 1980
Many widely used engineering formulas dealing with wind-generated waves have been derived with the assumption that the distribution of instantaneous sea surface elevations is described by the Gaussian distribution law. When real wave conditions are not well described by the Gaussian law, the propriety of theses formulas and designs based upon these ...

Statistical distribution of nonlinear random water wave surface elevation

Chinese Journal of Oceanology and Limnology, 2006
This study deals with the development of statistical modeling for water wave surface elevation by using a method that combines a dynamic solution with random process statistics. Ocean wave data taken from four NOAA (National Oceanic and Atmospheric Administration) buoys moored in the northeast Pacific were used to validate the model.

Determining water surface elevation in tidal rivers by ANN

Proceedings of the Institution of Civil Engineers - Water Management, 2008
Fluvial flows and tidal flows are governing on tidal rivers while fluvial flows are governing on non-tidal rivers alone. In addition to analytical and numerical models, stochastic methods must be considered to determine water surface elevation at the tidal limit of tidal rivers because hydraulic routing of this reach is very complex.
