Late Quaternary (Pre-Holocene) Coastal Systems of New Jersey
The coastline and the area adjacent to the present shoreline of New Jersey has not been explored as intensely as the same region of neighboring states for pre-Holocene high sea level stillstands....
Spit Formation in Lake and Bay
A technique of superimposing beach profiles, as a method for analyzing the characteristics and deformation process of a sand spit topography, is proposed, and the morphological changes...
Controls on Sand Resources: Cape Canaveral Area, Florida
Analysis of Holocene stratigraphy and sediments of the continental shelf off Cape Canaveral Florida shows that three basic factors control the quality of sand resources. Antecedent topography...
Topographic Responses to the Construction of Large Port Structures on Oarai Coast
Large offshore breakwater and groins have been constructed at Oarai Port, Japan. As a result, the coast experienced significant topographic changes. In this paper, the responses of the...
Computer Modeling of Reservoir Sedimentation and Sluicing
A recently developed computer program which simulates the evolution, growth, and movement of a submerged delta in reservoirs was tested for Spencer Dam and Reservoir in Nebraska. The code,...
Field Measurement of Topography at a River Mouth
The authors have been measuring topography and cross section at the river mouth of the Nanakita River, in Japan. Changes of short-time scale, such as straightening of the river channel...
Bed Topography and Sorting in Alluvial Channel Bends
A quasi-three-dimensional model has been developed for the purpose of calculating the velocity distribution, the bed topography and sediment sorting along channel bends. The depth-averaged...
Sorting of Mixed Sand on a Two-Dimensional Beach
A numerical method is developed to predict temporal variations of the sea bed topography and the bed-material composition. The predicted results are compared with the measurements in a...
Closed Conduit Vapor Lock
Closed conduit vapor lock can occur when a cross country liquid pipeline is displaced with a gas and the gas is allowed to get ahead of the liquid/gas interface. A simple hydraulic model...
Retention of the First Inch of Runoff in Coastal Areas
More and more state agencies are requiring development to retain the first inch of runoff from impervious coverage and release this runoff only through evaporation and/or infiltration....
Vacuum Sewers: Fundamentals and Design Methods
Vacuum sewer (VS) systems have important advantages over conventional gravity sanitary sewers or septic tank-soil absorption systems when one or more of the following conditions hold:...
Computations of High-Velocity Flows on Alluvial Fans
The results of numerical models of supercritical flows on alluvial fans demonstrate the strong effect fan topography has on flow velocity and depth. Particularly important are transverse...
Flow Field and Bed Topography in River Meanders
A mathematical model is developed for the calculation of flow field and bed topography in curved channels with an erodible bed. A small perturbation approach is used to linearize the governing...
Disturbance and Community Development
This paper reports on the recovery of nearshore vegetation after Hurricane Allen in 1980, change in roadside vegetation throughout a year, and the early re-establishment of vegetation...
Wetland Enhancement Near Columbia River Mile 68
The May 18, 1980 and subsequent eruptions of the Mt. St. Helen's volcano, and consequential ashy river sedimentation have caused major changes to a wetland adjacent to Carrolls...
Small Hydropower Potential in Missouri
The hydropower potential of small head plants on the Gasconade River was investigated. Since, it is felt that small head plants will have less environmental impact, thus it will be more...
Three-Dimensional Plotting in Dam Potentials
Hydroelectric development is important to many basins in the western United States. Topographical studies are normally used to arrive at sites to be chosen for further investigation of...
Orthophotoquad Mapping Program for Alaska
The U. S. Geological Survey (USGS) is the lead civilian mapping agency in the United States and is responsible for creating and maintaining numerous map series. In Alaska the standard...
Accumulation of Streamflow in Complex Topography
A proposed synthetic watershed model which simulates the hydrologic process of both overland flow and interflow is presented in this paper. The synthetic model has features designed to...
Microcomputer Application in Predicting Upland Erosion
An erosion-deposition model, originally developed for a mainframe computer, was adapted for an Apple IIe. With minimal adjustment it can also be used on other personal microcomputers....
