New Technology in Coastal Wave Monitoring
The Coastal Data Informational Program (CDIP) is an extensive network for monitoring waves along the Pacific coastlines of the US. The system has evolved substantially since its inception...
New Program for the Marine Observation and Prediction Center of the Central Weather Bureau
With the increase of economic activities on the oceans and seas, the observation of marine phenomena and forecast services become more and more significant. The Central Weather Bureau...
Second Order Directional Wave Kinematics in Shallow Water
A theory numerical procedure were developed earlier to represent a real sea by the sum of many linear and second order directional wave components. Earlier publications showed that including...
Implementing a National Wave Monitoring Network?Some Lessons and Plans
Most environmental problems involve a chemical and/or biological component and a physical processes component. A holistic approach must consider both components and the way they interact....
Low-frequency Fluctuations of Suspended Sand and Wave Groups in the Surf Zone
Field observations of the sand suspension near the bottom in surf zone are presented and discussed. Calculated spectra of suspended sand concentration and wave envelope was found to be...
On Hurricane-Generated Seas
Two different situations in the relationship between wind speed and sea severity during hurricanes (and tropical cyclones) are clarified from analysis of measured data obtained by NOAA...
A Comparison of Wave Statistics in Uni- and Multidirectional Shoaling Seas
the transformation of six unidirectional and multidirectional seas propagating over a 1:25 planar beach are examined in a series of laboratory experiments. In all cases, the mean wave...
A Second-Generation Wave Model for Coastal Wave Prediction
A second-generation numerical wave model, WINDWAVE, has been developed for wave prediction in coastal regions. The modal is based on the numerical integration of the energy balance equation...
Physical Modelling of Multidirectional Waves
A sixty-segment wave generator has been used since 1985 at the Coastal Engineering Laboratory of the National Research Council (NRC) of Canada to generate multidirectional waves, and study...
Wave Run-Up and Reflection on a Permeable Sea Wall
The swash oscillation on a sloping seawall made of step-shaped concrete blocks, waves and water particle velocity in front of the seawall were measured. It was inferred that incident waves...
The Significance of Hydrodynamic Forces in Coastal Embankment Design
The dynamic forces of sea water and backfill soil acting on coastal embankment are analyzed by using a new finite-difference method. The Euler's equation and continuity equation are used...
Environment-Friendly Deicing/Anti-Icing Fluid
NASA Ames has formulated a unique candidate non-glycol based freezing point depressant (FPD) fluid material that performs essentially the same or superior to currently used glycol based...
Intentions and Credences ? An Australian Approach to Computerised Building Regulation
In the past, computer representation of building regulations has addressed a series of prescriptive requirements. Compliance with each requirement was essential and the only relationship...
Climate Warming and Great Lakes Management
A decision-analysis approach to determining the relevance of information on climate change for near-term Great Lakes management decisions is outlined. Simplified applications to decisions...
Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...
Estimation of Mean Velocity for Flow Under Ice Cover
Methods of estimating mean velocity in a vertical from point velocity measurements are compared for an ice-covered channel. The comparison is based on velocity profiles obtained from a...
Effects of Simulated Ice on the Performance of Price Type-AA Current Meter Rotors
Slush ice readily adheres to the standard metal rotor of the winter Price type-AA current meter and affects the ability of the meter to measure the flow velocity accurately. Tests conducted...
Innovative Instrumentation for a Physical Model of River Ice Transport
Large physical models often require the use of innovative instrumentation and measurement techniques. Hydraulic models that attempt to simulate the effects of stationary ice covers put...
Kent, Edward
In order to perform conservative scour analyses for coastal bridge sites it is necessary to develop realistic hydraulic simulations which provide worst case estimates of depth and velocity....
Ice Accumulation Rate and the Geometry of Ice Jams in River Bends
Experiments on development of ice jams in river bends were performed in a 2.60-m-wide bend flume with a sand bed and 5-mm-diameter plastic beads simulating ice particles. The ice particles...
