Abstract

THE PREDICTION OF THE CHANGE REGIME IN THE SEDIMENTATION MOVEMENTS IN COASTAL AREAS AND CONSEQUENTLY, THE LONG-TERM COAST SHAPE CHANGES CAUSED BY HUMAN ACTIVITIES, INCLUDING BUILDING VARIOUS STRUCTURES AND COAST MATERIAL REMOVAL OR ACCUMULATION IS A SIGNIFICANT ISSUE IN DESIGNING PROJECTS IN COASTAL AREAS. IN CASES WHERE THE CAUSE OF UNWANTED EROSION OR SEDIMENTATION CANNOT BE ELIMINATED, OR IN ORDER TO PRESERVE THE ARTIFICIAL COAST, IT IS OFTEN NECESSARY TO BUILD SOME COASTAL STRUCTURES. IN DESIGNING STRUCTURES TO PREVENT UNFAVORABLE COASTAL CHANGES AND TO FIND THE EFFICIENT SIZE AND LOCATION OF THE STRUCTURES, IT IS CRUCIAL TO IMPLEMENT A MODEL TO SIMULATE THE PROCESS. THE COST, TIME AND EQUIPMENT REQUIRED FOR BUILDING PHYSICAL MODELS, AND COMPUTER TECHNOLOGY ADVANCES IN RECENT YEARS HAVE MADE MATHEMATICAL MODELING A POWERFUL INSTRUMENT IN THIS FIELD. IN THIS ARTICLE, WHILE BRIEFLY REVIEWING THE SEDIMENT TRANSFER AND ITS EFFECTIVE FACTORS, A MATHEMATICAL MODEL (ACCORDING TO THE SINGLE-LINE THEORY) IS PRESENTED IN ORDER TO SIMULATE THE LONG-TERM CHANGES OF THE COASTLINE NEAR THE COASTAL STRUCTURES. AFTER DESCRIBING THE THEORETICAL PRINCIPLES AND THE RELEVANT EQUATIONS, THE LIMITED DIVERSITY METHOD AND NUMERICAL SOLUTION ALGORITHM FOR THE EQUATIONS ARE PRESENTED. IN THE END, WHILE THE RESULTS OF THE IMPLEMENTATION OF THIS MODEL FOR SOME STRUCTURES ARE PRESENTED, SOME OF THE FACTORS AFFECTING THE MODEL AND THE IMPORTANT FACTORS OF DESIGNING THESE STRUCTURES ARE DESCRIBED.
