Freshwater Flow from Caves at Chankanaab Park, Cozumel, Quintana Roo, Mexico
The freshwater forms a lense on top of the ocean water and discharges to the ocean through solution channels. One such solution channel is present in Chankanaab Park and is identified...
Measurements of Mean Velocity, Turbulence and Temperature in a Deflected, Heated Water Jet
A submerged heated water jet issuing from a vertical wall into a turbulent flow in a rectangular open channel is investigated experimentally to determine the mean velocity, turbulence...
Submerged Flow in Parshall Flumes
Recent data collected in a 1-foot Parshall flume located in the Bureau of Reclamation's hydraulic laboratory indicate a significant discontinuity in the discharge/submergence...
21st Century Astronomical Observatories on the Moon
The advantages and disadvantages of building astronomical observatories on the Moon are described. In many ways, the Moon is a superior environment for astronomy to that of the Earth's...
The Physics of Sediment Transport by Wind and Water
Sponsored by a special projects committee under the guidance of the Sedimentation Technical Committee of ASCE. This collection contains noteworthy,...
Settlement of Residual Soils
The method previously suggested by the author in 1977 for calculating settlement of non-plastic to slightly plastic Piedmont Physiographic Region residual soils is reviewed. Additional...
Quantification of Net Shore-Drift Rates in Puget Sound and the Strait of Juan de Fuca
The objective in this study was to determine the annual rate of net shore-drift at selected sites within Puget Sound and the Strait of Juan de Fuca. These sites were selected based on...
Inlet Dredging Production as a Function of Sea State
This paper attempts to explain some of the inaccuracies and discrepancies in present methods of measuring dredging volumes and looks at a comparison of measured dredge volumes to natural...
Barbers Point, Oahu, Hawaii Deep Draft Harbor Monitoring Program
The deep draft harbor at Barbers Point, Oahu, Hawaii is located on the south side of the island. The 92 acre harbor basin is a product of over 25 years of planning and engineering. The...
Comparing Results of Wave Data from Two Recorders
In this paper two sets of wave measurements made in the same region using a pressure transducer and a wave rider bouy are compared. The same methods of analysis were applied to both the...
Practical Application of Acoustic Doppler Profilers
This paper discusses the advantages and limitations of the acoustic Doppler current profiler (ADCP), and it reviews some of the experience gained to date with the ADCP relevant to currents...
A Program to Acquire Deep Ocean Tsunami Measurements in the North Pacific
Deep ocean tsunami measurements are needed to provide open ocean boundary conditions for testing numerical models in hindcast studies, and for improving our understanding of tsunami generation...
Assessment of Pore Fluid Effects Using Flexible Wall and Consolidation Permeameters
Hydraulic conductivity tests were conducted on compacted soil specimens prepared at activities of 0. 36, 0. 60, 1. 00 and 1. 39 at a fine fraction of 25 percent. Na-montmorillonite, Georgia...
The Use of Cone Penetration Testing for Evaluation of Waste Disposal Alternatives
Geotechnical information derived from cone penetration testing (CPT) has been found to give increased accuracy in the siting of waste disposal facilities and in the design of remedial...
Physical Modeling of Contracted Flow
Experiments on steady flow over uniform grass roughness through centered single-opening contractions were conducted in the Flood Plain Simulation Facility at the U. S. Geological Survey's...
Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
Estimating Average Velocity in Cobble-Bed Channels
A data set obtained from natural channels having D//5//0 less than 64 mm and d/D//5//0 in the range of 3 to 20 is used as a basis for testing equations proposed by Limerinos, Thompson...
The NOS Experience in Real-Time Measurements of Tidal Currents
NOAA'S National Ocean Service (NOS) uses the term RADS, Remote Acoustic Doppler Sensing, for a new class of oceanographic instruments that uses acoustic backscatter to probe...
Flume Measures Ultra-Wide Discharge Range
Advances in mathematical modeling in the mid-1970's have led to accurate modeling of discharge and energy loss characteristics of long-throated flumes. A complex long-throated...
Laboratory Study of Mud Flows
In the study reported depth profiles and tip velocities were measured for a series of unsteady mud flows generated in a laboratory flume using a dam break scenario. Observation of a wide...
