Onsite Compliance Programs for Major Oil and Gas Projects
Major oil and gas projects developed in Santa Barbara County are monitored for compliance with conditions of approval through various enforcement and compliance programs. the Resource...

Risks of Transporting Petroleum and Other Materials from Offshore Oil and Gas Development
Oil and gas development offshore Santa Barbara County has lead to the preparation and adoption of local policies and mitigation programs specifically addressing the risks associated with...

Turbulence Measurements and Parameterizations
Bottom boundary layer and exchange models account for high frequency turbulence via Reynold's averaging and the most advanced closure formulations required by this averaging...

Infragravity Driven Suspended Sediment Transport in the Swash, Inner and Outer-Surf Zone
Nearbed suspended sediment concentration and velocity measurements from 3 field sites in the mid-outer surf zone (low energy), inner surf zone (high energy) and swash (high energy) are...

Critical Examination of Longshore Transport Rate Magnitude
Inconsistencies in the field data and predictions of longshore sediment transport (LST) rates associated with the CERC and Bagnold formulae are discussed. Practical errors in direct application...

Alongshore Sediment Transport Rate Distribution
The initial analysis of a new set of experimental data on alongshore sediment transport rate distribution is presented. The distributions were generally found to be bimodal but tended...

Measurements of Suspended Sediment Transport: Prototype Shorefaces
Field measurements of local time-varying suspended sediment flux were obtained using rapid response velocity and sediment concentration sensors at a number of elevations under shoaling...

Field Measurements of the Vertical Structure of Suspended Sediment
The use of acoustic backscatter measurements to determine suspended sediment concentration gives a new view of the instantaneous sediment distribution as a function of height above the...

Monitoring the Response of the Inter-Tidal Beach Profile to Tidal and Wave Forcing
The need for sets of beach profile and wave data of one year duration, sampled at sub-weekly intervals, is well recognised in the literature. Some of the initial data from a macro-tidal...

Cross-Shore Sediment Transport Modelling and Comparison with Tests at Prototype Scale
A series of prototype scale laboratory experiments have been performed at the Large Wave Channel (GWK) in Hanover to investigate the process of sediment transport over a horizontal bed...

Phase Speed and Angle of Breaking Waves Measured with Video Techniques
The phase speed and incident angle of breaking surface gravity waves in the surf zone are measured using video processing techniques. The analysis of video data follows two lines. The...

Simulation of Bedload Transport of Marine Gravel
Using combined current meter and acoustic measurements, detailed concurrent time series of instantaneous bedload transport rates and flow turbulence have been obtained. The duration, interval...

Bedload Transport Measurement by Imaging of Tracers
A dyed-sand tracer technique is developed for investigation of bedload under laboratory oscillatory flows. Imaging of the tracer with high speed photography allows the creation of time...

Bedload Transport Under Low Frequency Waves
The concept of a bedload spectrum, showing the distribution of energy with frequency in the bedload process, is proposed. The bedload process is thus analysed in the frequency rather than...

Equilibrium Profile of a Beach with Varying Grain Size
The classical concave equilibrium profile shape proposed by Bruun (1954) and Dean (1977) is modified to incorporate a varying grain size across-shore. On most beaches the median grain...

Computer Simulation Modeling of Ebb-Tidal Deltas
An ebb-tidal delta simulation model has been developed incorporating gross features of delta and channel morphologies which can be measured from vertical aerial photographs. Delta and...

Processes of Shoreline Change Along the Nile Delta Coast of Egypt
A comprehensive program has been underway for more than a decade to collect nearshore data related to erosion problems experienced along the shoreline of the Nile Delta. The data include...

Beach Profile Modelling: Flume Data Comparisons and Sensitivity Tests
Some results from a deterministic computational model of beach and nearshore profile development are presented in this paper. Comparisons are made with prototype-scale flume measurements...

Higher Frequency Acoustic Measurements of Coarse Bedload Transport
Although sensors have been developed which provide high temporal resolution for the measurement of wave profiles, flow fields and suspended sediment concentrations within the coastal system,...

Standing Wave Measurements of Bedload Thickness: Feasibility in an Air System with Model Sediment
A novel technique would yield information about bedload thickness from measurements of a standing wave pattern produced by a sound source insonifying the bottom at normal incidence. The...
