Bedform Dynamics and Mine Burial
Large bedforms in the nearshore (with heights of 10 – 50 cm and lengths of 1-10 m) are observed to occur frequently and to be ubiquitous throughout the surf zone (e.g., Clifton et al. 1971, Gallagher et al. 2002, Hay and Wilson 1994, Thornton et al. 1998). However, their dynamics are poorly understood and they are generally neglected in models of sediment transport, morphology change and nearsh...
متن کاملRanging performance of satellite laser altimeters
Topographic mapping of the earth, moon and planets can be accomplished with high resolution and accuracy using satellite laser altimeters. These systems employ nanosecond laser pulses and microradian beam divergences to achieve submeter vertical range resolution from orbital altitudes of several hundred kilometers. In this paper we develop detailed expressions for the range and pulse width meas...
متن کاملBedform climbing in theory and nature
Where bedforms migiate during deposition, they move upward (climb) with respect to the generalized sediment surface. Sediment deposited on each lee slope and not eroded during the passage of a following trough is left behind as a cross-stratified bed. Because sediment is thus transferred from bedforms to underlying strata, bedforms must decrease in cross-sectional area or in number, or both, un...
متن کاملImproved procedures for estimating amplitudes and phases of harmonics with application to vibration analysis
In this paper, we propose two procedures for accurate amplitude and phase estimation of multifrequency signals in rotating machinery. The first method reduces the amplitude attenuation and phase shift caused by the “nonflat” top of the main lobe of the window. The second procedure is able to reduce not only the leakage effects due to windowing but also the distortion that appears when the rotat...
متن کاملNearshore Processes
Our approach is to test hypotheses by comparing model predictions with field observations. Waves, currents, and bathymetry were observed on a natural beach during the SandyDuck field experiment on the North Carolina coast. Pressure gages, current meters, and sonar altimeters were deployed on a grid extending 370 m from near the shoreline to about 5 m water depth and spanning 200 m along the coa...
