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...

The Effect of Beach Slope on Oscillatory Flow Bedload Transport
The data for five laboratory sloping bed bedload sediment transport experiments are presented. Each consists of a series of half cycle transport rate measurements using the same waveform...

Trapping and Escape of Fine-Grained Sediments: Neuse River Estuary, N.C.
The Neuse River estuary and its receiving basin, Pamlico Sound, are part of a system that comprises large, shallow bodies of water which have little or no free connection with the open...

Observation of Suspended Sediments in Mobile Bay, Alabama from Satellite
As part of a comprehensive geologic study of coastal Alabama and Mississippi, the U.S. Geological Survey is investigating coastal sediment transport in Mobile Bay and the adjacent shelf....

An Engineering Evaluation of Fine Sedimentation at the Mayport Naval Basin, Mayport, Florida
The Mayport Naval Basin is located near the mouth of the St Johns River in northeastern Florida, U.S.A. A total of 16.8 million cubic yards of fine sediment were dredged from the harbor...

Fine Grain Sediment Transport and Deposition in the Atchafalaya and Chenier Plain Sedimentary System
The most extensive land loss and land accretion processes in the U.S. are occuring in the Mississippi River Delta Plain. Some 40 square miles of valuable marshlands are lost annually....

Conglomeratic Shoreface Deposits from the Cretaceous Cardium Formation, Alberta, Canada
Conglomeratic shoreface deposits of the Upper Cretaceous Cardium Formation are well exposed at an outcrop in northwestern Alberta. The conglomerates there compose over 80% of the total...

Geologic Controls on the Formation and Evolution of Quaternary Coastal Deposits of the Northern Gulf of Mexico
A study of the barrier islands and wetlands in the deltaic plain of Louisiana is presented. Its purpose was to document rapid changes and to learn more about the processes responsible...

Processes Controlling the Retreat of the Isles Dernieres, A Louisiana Barrier-Island Chain
The Isles Dernieres is a low-lying, transgressive barrier-island chain situated about 150 km west of the modern Mississippi delta. Much of the Isles Dernieres consists of highly dissected...

Cyclonic Events and Sedimentation in the Gulf of Mexico
An ample literature exists documenting the destructive effects hurricanes have upon offshore barrier islands and coastlines. The Gulf of Mexico region has been especially heavily impacted...

Sand Bypassing at Indian River Inlet, Delaware
To solve a beach erosion problem north of Indian River Inlet, Delaware, the US Army Corps of Engineers Philadelphia District and the State of Delaware have constructed a fixed plant sand...

Effects of Sea Level Rise on the Mississippi River Delta Plain
Geologic studies of the Mississippi River delta plain and continental shelf reveal the occurrence of several relative sea level stillstands during the last stages of the Holocene transgression....

Processes of Sediment Transport and Ebb Tidal Delta Development at a Jettied Inlet
This paper deals with the development of the ebb tidal delta following the extension of jetties at a tidal river entrance. The growth rate and morphological change are discussed using...

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...

Movable-Bed Model Study of Storm-Induced Beach Fill Erosion at Ocean City Maryland
Movable-bed physical model scaling guidance has recently been validated for the case of turbulent-dominated sediment transport, such as occurs in the surf zone. The tests successfully...

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...

Planning Subsurface Storage-Transport Facilities for Combined Sewer Overflow Control in Cincinnati, Ohio
The wastewater collection system in the greater Cincinnati area includes a large area served by a combined sewer system. The combined sewer system drains to the Ohio River and several...

Economic Evaluation of Minimum Flow at Rockton
The Rockton Hydroelectric Project is a two-unit, 1,100 kW plant operated by South Beloit Water, Gas & Electric Company, a wholly owned subsidiary of Wisconsin Power & Light...
