Chatham Bars Inlet

Shoaling of Waves Under Ice
In winter, ice is often present along the shores of water bodies. The vertical motions of such ice can affect winter coastal dynamics and structures supported by offshore pilings. These...

Channel Erosion in Southwestern Louisiana Canal
Geomorphic processes active in the man-made Southwestern Louisiana Canal are studied with the aid of color infrared and multiband imagery aerial photography and various field analysis...

Bed Form Response to Nonsteady Flows
The rate of response of bed forms and the coexistent bar roughness of a sand bed in a laboratory flume to changing hydraulic conditions was studied. Sophisticated electronic feedback control...

Shoaling Rate Prediction Using a Sedimentation Tank

Flat-Vee Weirs in Alluvial Channels
Sediment tests were carried out with the ultimate aim of providing design data for flat-vee weir installations in alluvial channels. The model study was of an idealized nature but did...

Wind-Induced Circulation in Shallow Water
Equations are derived for the computation of the three-dimensional circulation of water in shallow basins caused by steady wind. The equations are applicable to any wind-stress distribution...

Water Wave Pressure on Horizontal Plate
Simple rules are developed to estimate the maximum uplift pressures induced on the underside of a flat plate by various types of incident waves. Theoretical prediction techniques are provided...

River-Coast Interaction: Laboratory Simulation
The flow of a river into the ocean is often obstructed by a sand bar at the river mouth. The interaction of a river with the coast can be simulated in a hydraulic model with a movable...

Salinity Intrusion Effects in Estuary Shoaling
In the salinity intrusion region of an estuary the internal velocity distribution in the longitudinal direction is modified by the density effects. If the velocities are averaged over...

New Horizons in the Field of Tidal Hydraulic
Tidal hydraulics is currently defined to include all aspects of tidal waterways, not merely the rise and fall of the tide and the resultant tidal currents. The states of knowledge in the...

Shoaling of Solitary Waves on Small Slopes
It is proposed that solitary waves can be used as the initial wave shape to simulate the shoaling and breaking of large, long waves on a beach. Experiments were conducted with solitary...

Weak Reflection of Water Waves by Bottom Obstacles
For a gradually varying bottom, an approximate theory is developed for the calculation of scattering properties of two-dimensional water waves. An integral representation is first formed...

Tidal Inlets Housekeeping
A tidal inlet on an alluvial shore presents a littoral barrier which must be overcome by flushing and bypassing of material. Presumably, the tidal inlet arranges itself in the most practical...

Sediment Transport in a Coastal Plain Estuary
Observations of net flow and suspended sediment were made in the Rappahannock Estuary, Virginia, to delineate patterns of transport that lead to partial entrapment of sediment in the middle...

Model Tests of Enlarged Navigation Channel at Miller Sands Bar, Columbia River Estuary

Wave Breakers on a Beach and Surges in a Dry Bed
The problem of wave breaking and wave run-up is treated by the method of characteristics. The cases of a spilling (nonsaturated) breaker, fully developed bore traveling in shoaling water...

Laminar Damping of Oscillatory Waves
Shearing stresses exerted on smooth horizontal bottom by progressive, shallow-water waves are investigated in laminar regime; average surface resistance and amplitude attenuation coefficients...

Prototype Measurements of the Columbia River Estuary
Development of navigational regulation of estuary since 1882 is reviewed; measurement program to define environmental conditions affecting shoaling; description of types of directional...

Shoaling of the Lower Hudson River
Investigation on sources of sedimentation, characteristics of fresh and salt water components of flow within estuary, quantity of shoaling which occurs, and fundamental principles affecting...
