BEACH MORPHODYNAMICS AND COASTAL PROCESSES ALONG TELUK CHEMPEDAK TO KUALA PAHANG, PAHANG, MALAYSIA BY MOHD ZAINI BIN MUSTAPA A thesis submitted in fulfilment of the requirement for the degree of Doctor of Philosophy in Education Kulliyyah of Science International Islamic University Malaysia FEBRUARY 2017 ABSTRACT The present study on the beach morphology and its profile dynamics along the selected beach of Pahang comprising the areas from Teluk Chempedak to Kuala Pahang. Beach stations were monitored monthly for a complete 1-year cycle; beginning from February 2012 to February 2013 at 12 corresponding stations established at random morphological intervals. The aim of the study is to determine the morphological development of the respective beach based on profile alteration, including the erosional and depositional rates and other ambient littoral morphodynamic factors including sediment grain-size analysis. Topographic beach profiles were surveyed using an electronic theodolite in order to attain composite height, distance, and slope of the beach. Analysis on the beach process activity was extended for numerical modelling simulation in order to understand the physical processes involved. Analysis of beach profile changes revealed that minor changes at dune and high-tide zone with a negligible rate of either erosion or deposition for most stations. The northeast monsoon activity has transported the sediment away from the stations causing most stations experienced erosion. However, the process of deposition took place at most stations that could be noticed at the mid-tide level and some extent of low-tide areas throughout the post-northeast monsoon season. The beach slopes were ranged from 0.98° to 6.26° and indicates most beaches have a gentle slope with lower degree value. The quartz sand was found along the study area with domination of fine grain sediment with medium and coarse fractions obtained at certain sites. Model simulation implied that the selected domains are classified as transported area, which having more tendencies to become eroded if any disturbance introduced such as development to the area without proper design and planning. Periodically, changes in currents, tides and wave action, however, produced a normal cycle if the virginity of the beach remains unchanged. The necessity of understanding of these factors is high as to maintain the sustainability for both natural and human systems. ii خﻻصة البحث ABSTRACT IN ARABIC ُصممت هذه الدراسة لفهم تشكل الشاطئ والديناميكا اجلانبية على طول الشاطئ يف مناطق خمتارة من ابهانج تضم مساحات من شاطىء جيمباداك إىل كواﻻ ابهانج. مت رصد حمطات الشاطئ الشهرية لدورة كاملة ملدة سنة؛ ابتداء من فرباير 2012 إىل فرباير 2013 يف 12 حمطة ومت إنشاء حمطات ماابلة يف فرتات مورفولوجية عشوائية. اهلدف من هذه الدراسة هو حتديد وضع تطور مورفولوجية الشاطئ املخصص إستناداً إىل التغيري يف احملتوى، مبا يف ذلك معدﻻت التحات والرتسيب وغريها من العوامل مورفوديناميكية الساحلية احمليطة مبا يف ذلك حتليل حجم حبات الرواسب. مت مجع مظاهر الشاطئ الطبوغرافية ابستخدام املزواة اﻹلكرتونية من أجل حتايق ارتفاع املركب وبعد املسافة وإحندار الشاطئ. مت متديد التحليل على نشاط عملية الشاطئ حملاكاة النماذج العددية من أجل فهم العمليات الفيزايئية املعنيّة. كشف حتليل حمتوى تغريات الشاطئ أن هنالك تغيريات طفيفة يف الكثبان الرملية ومنطاة املد مع معدل ﻻ يذكر إما آتكل أو ترسيب ملعظم احملطات. وقد نال نشاط الرايح املومسية الشمالية الشرقية الرواسب بعيدا عن احملطات مما تسبب آتكل قوي يف معظم احملطات. ومع ذلك، جرت عملية الرتسيب يفمعظم احملطات اليت ميكن أن تكون يف مستوى منتصف املد والبعض موجود يف مناطق اجلزر طوال موسم الرايح املومسية ما بعد مشال شرق البﻻد. تراوحت إحندرات الشاطئ من 0.98 درجة إىل 6.26 درجة وتشري معظم الشواطئ هلا منحدر طفيف مع أقل قيمة. مت العثور على رمل الكوارتز على طول منطاة الدراسة مع هيمنة حبات الرواسب الناعمة مع كسور متوسطة وخشنة اليت مت احلصول عليها يف بعض املواقع. ابلنسبة جلزء اهليدروديناميكية، تضمن منوذج احملاكاة أن تصنف اجملاﻻت املختارة كمنطاة مناولة، اليت لديها املزيد من امليول لتصبح متآكلة إذا حدث أي اضطراب مثل تنمية املنطاة دون تصميم وختطيط سليم. على حنو دوري، التغريات يف التيارات واملد واجلزر وحركة اﻷمواج، ومع ذلك، أنتاج دورة طبيعية للشاطئ دون تغيري. ضرورة فهم هذه العوامل هي مهمة للحفاظ على استدامة كل من النظم الطبيعية والبشرية. iii APPROVAL PAGE The thesis of Mohd Zaini Mustapa has been approved by the following: _____________________________ Shahbudin Saad Supervisor _____________________________ Muhammad Salihi Abdul Hadi Co-Supervisor _____________________________ Kamaruzzaman Yunus Co-Supervisor _____________________________ Normawaty Mohammad Noor Internal Examiner _____________________________ Rosnan Yaacob External Examiner _____________________________ Ejria Saleh External Examiner _____________________________ Norlelawati A.
