Numerical Beach Profile Modelling for Beachfill Projects
The use of beachfill in addressing coastal erosion problems is becoming increasingly popular. It is often more attractive than the conventional structural approaches for economic, aesthetic...

Similarity Solutions of Starting Jets and Starting Plumes
Similarity solutions of the starting jets and the starting plumes are obtained using a one dimensional model based on the top-hat profiles and the symmetry assumption for the velocity...

Pulmonary Artery Velocity Profiles in Young Lambs
This report describes progress made in our laboratory in examining pulmonary artery velocity patterns in normally maturing lambs. Lambs from four age groups were selected for study--2...

An Expert System for the Planning and Design of Flood Control Channels
The planning and design of flood control channels often calls for the evaluation of a unique set of physical conditions which do not lend themselves to standard designs. Consequently,...

A Comparison of Accuracies of Steady Water Surface Profiles
The author compares the effect of varying boundary conditions and cross sectional spacing on one dimensional steady water surface profiles. Six streams are modeled using both the 10 and...

Numerical Modeling of Storm-Induced Beach Erosion, Folly Beach, South Carolina, Beach Fill Alternatives
The U.S. Army Engineer District, Charleston (SAC), is developing a National Economic Development (NED) Plan for providing northeaster and hurricane storm protection for the municipality...

Long Term Assessment of Beach Nourishment Project Performance
Long-term data on profile response, sediment distribution and wave information have been collected and analyzed for the Indialantic/Melbourne Beach beach nourishment project in order to...

Effect of Shell on Beach Performance: Examples from the West-Central Coast of Florida
Time-series analysis of beach profiles and sediment analysis along the Pinellas County coast of Florida over a 2-yr. period shows that shell abundance has an influence on beach performance....

Beach and Cliff Erosion Processes at Solana Beach, California, 1984-1990
Observations of back beach elevation changes, profiles and cliff erosion over a 7-year period from 1984-1990 provide a detailed local view of these processes and rates at a typical Southern...

Saline Intrusion in Marine Effluent Outfalls
The paper presents an experimental investigation of saline intrusion in long sea outfalls. This intrusion is caused by the influx of sea water that may occur during periods of low discharge,...

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...

Engineering Methods for Predicting Beach Profile Response
This papers contains a review of so-called 'engineering methods' for predicting beach profile change based on equilibrium profile concepts. In the first part...

Problems Associated with Deterministic Modelling of Extreme Beach Erosion Events
Recent developments in numerical modelling of cross-shore sediment transport and beach profile evolution have generally been based on a deterministic approach to the problem. That is to...

Beach Profiles vs. Cross-Shore Distributions of Sediment Grain Sizes
In the present paper, field results are reported from various tideless beaches in Greece with mixed sedimentary environments. The two classical beach profiles are examined in terms of...

Effect of Varying Sediment Size on Equilibrium Beach Profiles
Beach profiles from four field sites and accompanying data describing the cross-shore distribution of median sediment size are analyzed and compared to predicted profiles based on an equilibrium...

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...

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...

Beach Profile Response to Hurricane Hugo
The impact of hurricane Hugo on the beaches of South Carolina is examined by comparing beach survey data collected during the spring and summer of 1989 with post-storm survey data collected...

Numerical Simulation of Beach Profile Response to Hurricane Hugo
Beach and dune erosion caused by Hurricane Hugo at Myrtle and Debidue Beaches, South Carolina was simulated using an explicit finite-difference cross-shore sand transport numerical mode....

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...
