Model of beach processes and responses for a gradually shoaling 
sandy beach uninfluenced by tidal currents. 
(A) Definition sketch of problem; (B) degree of separation of 
boundaries of the jet flow for the inlet to be studied in 
nature. 
Model of (A) shoals at inlet entrance; (B) dynamic conditions 
during inlet outflow and under wave action; and (C) tendencies 
of mean size (Mz) and sorting (S,) in response to (B). 
Conceptual fluid process (A) sedimentary response; (B) model for 
area around inlet entrance under ebb tidal flow in presence 
of wave fronts approaching shoreline obliquely. 
Area of investigation, Rudee Inlet, and three transects where 
samples were taken. 
Position of inlet channel and sampling stations at Rudee Inlet on 
25 March 1963. Coordinates are Virginia Coordinate Systems, 
south zone. 
Sampling stations and scheme for U, V coordinate systems. 
Observed distribution of mean-grain-size values, expressed as 
nominal diameters (mm). 
Linear trend surface for mean size (mm). 
Deviations from linear trend surface for mean size (mm). 
Quadratic trend surface for mean size (arcuate contours) based on 
Rudee Inlet samples (large dots) and quadratic trend surface 
(straight-line contours) for mean size (mm) based on samples 
from the three transects (Figure 5). 
Deviations from quadratic trend surface for mean size (mm). 
Cubic trend surface for mean size (mm). 
Deviations from cubic trend surface for mean grain size (mm). 
Deviation of quadratic trend surface for whole beach from quadratic 
trend surface for Mz for the inlet area. Contour values are 
in mm.
