A Calibrated Longshore Transport Model for Richards Bay
In order to plan maintenance dredging at the Port of Richards Bay, different studies were carried out. These were to determine the extreme dredging rates required in the long term and...
Sand Movement by Wind?Optimising Predictive Power
The aim of the work reported here was to develop a model for the efficient utilisation of standard anemometer data for the prediction of potential sand movement. Accurate aeolian sand...
Estimation of Overwash Bore Velocities Using Video Techniques
Overwash data were collected at a site on the Isles Dernieres, LA barrier island chain during Hurricane Gilbert in September 1988. A video technique was applied that allowed the quantification...
Sand Ridges and Internal Waves on Continental Shelves
Large-amplitude internal waves generated by tidal fluctuations at the outer edge of the continental shelf propagate shoreward and interact with sediment on the shelf. A crude mathematical...
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...
Modelling of Cross-Shore Flow and Morphology
A one-dimensional, time-dependent model is presented which describes the evolution of wave groups and associated long waves over an arbitrary profile, in a short-wave averaged sense. Model...
A Model for Profile Changes During Storm Surges
In order to predict the amount of dune erosion due to a storm surge, a model for cross-shore transport during storm surges has been developed. During a storm with intensive wave breaking,...
Modelling of Cross-Shore Transport
The validity of cross-shore sediment transport modelling in terms of time-averaged velocities and concentrations has been investigated....
Onshore/Offshore Sediment Transport and Morphological Modelling of Coastal Profiles
This paper presents a deterministic model for the morphological evolution of a coastal profile for direct incoming waves. The model contains description of waves across the coastal zone,...
A Numerical Model of Beach Profile Change Due to Random Waves
A numerical model was developed for random wave deformation and the resultant beach profile change. The model consisted of short-wave model based on parabolic equation, long-wave model...
Comparison of Shoreline Change Obtained with Physical and Numerical Models
This paper describes a study performed to compare numerical simulations of shoreline response to coastal structures to the response measured in a large wave basin. Two cases are modeled...
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...
Mathematical Model of Groyned Shingle Beaches
The paper describes the development of a mathematical model designed to be used by coastal engineers to study the effects of groynes on shingle beaches. The main task of the model is to...
The Use of Hydraulic and Mathematical Models for Designing a Small Artificial Beach
This paper presents a case study in which physical and mathematical models are used for determining the behavior of a small artificial beach under wave attack. The beach is protected by...
Development of Optimum Beach Fill Design Cross-Section
Accurate beach profile surveys, wave information, and sediment data taken at Ocean City, Maryland provided an opportunity to evaluate four beach fill design alternatives using the beach...
Sediment Budget at Oceanside, California, Calculated Using a Calibrated Shoreline Change Model
A quantitative sediment budget analysis was made for the shoreline segment extending from 4 miles north to 4 miles south of Oceanside Harbor using a calibrated shoreline change model....
PITTLEACH: A Numerical Model of Landfill Stabilization
This paper addresses the theoretical development, use and application of PITTLEACH, a computer program conceived to simulate the processes of landfill stabilization. Since the physical,...
An Evaluation of Area Source Dispersion Algorithms
The correct simulation of air pollutant dispersion from area sources of pollutants has presented some unique challenges to dispersion modelers. This study employs geometric tests and sensitivity...
Propositions for Packed Bed Adsorption Reactor Design
This paper states ten propositions which describe the behavior of 'wave fronts', i.e., adsorbate concentration versus distance profiles at given elapsed times,...
Screening Level Modeling in Support of an Estuarine Toxics Management Program
Mathematical models will be used in the future to determine maximum allowable pollutant loading rates for several toxics to the South San Francisco Bay Estuary. This project consisted...
