Theoretical study of unstable waves in the rapids of the river
This paper examines how the velocity distribution in free-surface flow affects the kinematic and dynamic velocities of disturbance waves on hillslopes or in high-gradient rivers, thereby...

Numerical Analysis of High Velocity Flow with Zero-Depth Line and Oblique Shock Wave in Steep Open-Channels
This paper deals with the numerical analysis of 2D steady high velocity flows with the zero - depth line and the oblique shock wave in steep open channels by means of the method of characteristics....

Considerations in 2-D Modeling of Hydraulically Steep Flow
Simplifications in the equations used to describe shallow water flow lead to some difficulties in modeling supercritical flow. The hydrostatic assumption produces two significant differences...

Numerical Modelling and Laboratory Verification for the Turbulent Flow Field in the Branching Channel
Adopting the depth-averaged k-? turbulence model and using the finite volume method and SIMPLE procedure, the turbulent flow field in the branching channel is numerically solved and verified...

Factors Controlling Strong Ground Motion and Their Associated Uncertainties
Of special interest in strong ground motion modeling is a quantification of the degree of influence specific physical parameters have on the computed motions. Associated with the model...

In Situ Testing Performed at Jackson Lake Dam
Jackson Lake Dam was rehabilitated from 1986 to 1988 to increase seismic stability. Final foundation improvements consisted of dynamic compaction and mixed inplace soil cement columns....

Seismic Stability Modification Requirements for Pineview Dam
Pineview Dam is located 8 km upstream from Ogden, Utah, and about 8 km from the Wasatch Fault Zone. Preconstruction information and construction records available at the outset of the...

Pollutant Removal Efficiency of Detention Basins
A simple method is presented for quick estimates of pollutant removal efficiency of detention basins under dynamic conditions. The method is based on the generalized solutions to the reservoir...

Performance of Three Adjacent but Different Beach Nourishment Projects, Pinellas County, Florida
More than 25 million dollars have been spent on three adjacent nourishment projects extending along 10 miles (16 km) of central Pinellas Country on the Gulf Coat of Florida. The three...

Restoring the Beach Profile with Vegetation
Owing to the fast moving urban expansion of the city of Rio de Janeiro toward one of its most preserved coastal areas, Barra da Tijuca district, it was necessary to implement some substructure...

Coastal Erosion Analysis of the Belle Fontaine Area, Jackson County, Mississippi
The Belle Fontaine area contains the only remaining natural beach on the mainland Mississippi shoreline. The fine to medium-grained sand beach is the result of erosion and retreat of the...

Relationship Between Wave Climate and Performance of a Recently Nourished Beach, Indian Rocks Beach, Pinellas County, Florida
A large beach nourishment project was completed at Indian Rocks Beach on the central Gulf coast of Florida in December of 1990. The performance of the project has been monitored monthly...

Revere Beach and Point of Pines, Massachusetts, Shore Front Study
This paper describes a study conducted by the Coastal Engineering Research Center (CERC) to determine the degree of storm protection provided by an existing coarse beach fill at Revere...

Simulation of Beach Fill Response to Multiple Storms, Ocean City, Maryland
The beach fill project constructed over 1988-1991 at Ocean City, Maryland, includes nearshore wave and water-level measurements and high-accuracy beach profile sea-sled surveys performed...

Beach Morphology Analysis Package (BMAP)
This paper describes a newly developed personal computer software analysis package called BMAP, which stands for 'Beach Morphology Analysis Package.' The BMAP is an integrated set of beach...

The Profile Volume Approach to Beach Nourishment
The purpose of this paper is to outline a design approach to beach nourishment that emphasizes profile volumes. The advantages and disadvantages of the method are discussed and related...

The Specific Peculiarities of Relief Transformation and Shelly Sediment Differentiation in Coastal Zone
The settling velocities values of shelly sediment considerably differ from ones of the same particles of terrigeneous material and for this reason character and intensity of hydrodynamic...

Seasonal Morphological Evolution of Beach Profiles in Tropical Zone
A follow-up of the morphological evolution of Cote d'Ivoire Atlantic littoral for two yeas, from nine beach profiles between Grand-Bassam and Jacqueville showed a seasonal evolution of...

Coastal and Sand Spit Evolution from 1958 to 1992: Saloum River Mouth (Senegal, West Africa)
From the bathymetric map made in 1958 with the Marine Hydrographical Service in France (Number 6147), the 1976 Landsat imagery, the 1981 SPOT simulations, the 1991 SPOT data and the field...

Shoreline Erosion Along the East Coast of Ghana
Coastal erosion along the east coast of Ghana has been persistent within the Keta area since the beginning of the century and severe in the immediate fringes of the west of the Volta Estuary...
