Eustatic and Neotectonic Controls on Salt Marsh Sedimentation
This paper presents a revised conceptual model of the long-term evolution of back-barrier marshes on the macro-tidal north Norfolk coast and their adjustment to tidal levels. The present...
Computer Simulation Modeling of Ebb-Tidal Deltas
An ebb-tidal delta simulation model has been developed incorporating gross features of delta and channel morphologies which can be measured from vertical aerial photographs. Delta and...
Numerical Modelling of Lower Lias Rock Failures in the Coastal Cliffs of South Wales
A model has been developed to evaluate slope failure in the interbedded limestone and mudstone Lower Lias series which outcrop for some 30 km in coastal South Wales. Computer simulation...
Model Testing of Shore Protection Schemes at Surfside-Sunset Beach, CA
A 1:75-scale physical hydraulic model was used to investigate the design of proposed structural modifications at Surfside-Sunset Beach, California, with regard to beach erosion at the...
Physical Modelling of Pocket Beaches
The design of artificial beach systems is dependent upon the modelling criteria and on the selection of the sand material to be used for nourishment. In order to obtain a stable beach...
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...
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....
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...
Development of an Input Data Set for Shoreline Change Modeling
Procedures and analysis techniques for pre-processing physical data sets in preparation for performing a numerical shoreline change simulation study using the GENESIS model are presented....
Field Application of a Numerical Model of Beach Topography Change
Discussion was made, on the basis of field data, on the applicability of the formula for local rate of sediment transport due to combined action of waves and currents presented by Watanabe...
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...
Hydraulic Analysis of the Impacts of I/I on System Capacity
The USEPA Stormwater Management Model was used to evaluate the impact of infiltration and inflow on the separate sewer facilities of one of the largest sewage treatment districts in the...
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...
