  2. The effects of waves transformation, refraction, diffration, reflection and breaking are all due to the depth of water, varying topography, bottom friction, obstacles and current as waves proceed from offshore to near shore regions. some basic parameters which are relevant to the cost of buildings as well as the type of structures are determined by the wave factors since these projects are placed in near shore area, so it is of great importance to study the regularity of wave transforming

    外海波浪傳入近岸淺水區受水深、地形、底摩擦、障礙物以及水流等因素的影響,會發生變形、折射、繞射、反射和破碎等各種現象,然而大部分海洋及海岸工程位於近岸地區,該地區的波浪要素將是確定工程造價、建築物型式等最基本的參數,因此研究近岸地區波浪的變化規律具有重要意義。
