... ABSTRACT In this study, a new integrated methodology (WLRSM) for mapping tidal flats elevation is proposed, which integrates the waterline (WL) method and remotely sensed moisture (RSM) method. Level-1 DEM of tidal flats is provided by WL, and then improved furtherly by RSM. The level-1 DEM...

... and the Coriolis force (Klyachkin, May, 2012; etc.). The wind impact force is comprised of tangential and normal stresses and hence for calculation of this force it is necessary to know the area of cross- (vertical) section Sva and the area of horizontal section Sha (iceberg area by waterline) of the iceberg...

Department, CECI Engineering Consultants, Inc., Taipei, Taiwan China ABSTRACT In-site bathymetric measurements are too expensive to be sufficiently available for the investigation on beach changes. We proposed a series of image processing to detect waterlines from 31 satellite images over 12 years...

... be guaranteed throughout the computation. In order to trace the exact wave-body intersections i.e. waterline, the marker (intersection) is enforced to move along cross section line of body surface, which can take into account complex body geometry above still waterline. In the computation, HOBEM and 4th-order...

From the comparison of the characteristics of plural ship s aft frame lines, waterline volume coefficient wvC and bottom volume coefficient bvC were adopted as the parameters of sensitivity analysis. Consequently, the authors propose the measures of modifying aft frame...
