Abstract

THE PRESENT RESEARCH EVALUATES THE FORMATION AND DEVELOPMENT MODE OF SEDIMENTARY RIPPLES IN BED OF SAJAFI PORT NAVIGATION CHANNEL SITUATED IN DELTA OF ZOHRE RIVER. FOR THIS PURPOSE, NUMERICAL SIMULATIONS WERE DONE TOGETHER WITH THEORETICAL STUDIES. TO INVESTIGATE THE EFFECT OF TIDE AND WAVES ON FORMATION AND GROWTH OF SEDIMENTARY RIPPLES IN BED OF NAVIGATION CHANNEL, SOME SPOTS WERE CONSIDERED IN THE STUDY AREA. THE MODELING DONE FOR INVESTIGATING THE EFFECT OF TIDE SHOWS THAT RATE OF LEVEL CHANGE IN VARIOUS SPOTS IN THE NAVIGATION CHANNEL VARIES FROM 50 CENTIMETER EROSION TO 70 CENTIMETER SEDIMENTATION WHICH RESULTS IN FORMATION OF SEDIMENTARY RIPPLES INSIDE THE CHANNEL AND IN SOME PLACES INSIDE THE CHANNEL CAVITIES ARE FORMED WITH DEPTH OF ABOUT 50 CENTIMETER AND ABOUT 100 METER FARTHER SOME HILL ARE FORMED WITH THE HEIGHT OF ABOUT 40 TO 70 CENTIMETER. THESE SEDIMENTARY CAVITIES AND HILLS ARE BINARY. THE RESULTS OF THE MODELING ALSO REVEAL THAT THE DIFFERENCE OF WAVE’S PERIOD AND HEIGHT HAS NO EFFECT IN GROWTH STAGE, BUT IN SEDIMENTATION STAGE, WITH DECREASE OF WAVE’S PERIOD, THE SEDIMENTATION DECREASES AND WITH DECREASE OF WAVE’S HEIGHT, THE SEDIMENTATION INCREASES.
