Study on flood gate structure using physical hydraulics model

Study on flood gate structure using physical hydraulics model / Adliana Zaafarani Adnan
Banjir boleh ditakrifkan sebagai aliran air yang melebihi tebing semula jadi atau tebing buatan di bahagian sistem sungai. Banjir boleh mengakibatkan kehilangan nyawa dan aset, memberikan impak negatif terhadap sosial dan ekonomi kerana kos yang tinggi dalam pemulihan dan mengurangkan peluang pelaburan di kawasan banjir. Oleh itu, pelbagai cara telah diperkenalkan bagi mengurangkan masalah banjir telah dilakukan sebelum ini. Salah satu cara untuk mengurangkan bajir adalah penghadang banjir mudah alih. Penghadang banjir mudah alih dinamakan sebagai NADI1, NADI2 dan NADI3 dengan perbezaan mekanisma dan dimensi. Objektif kajian ini adalah untuk menentukan akibat tekanan air terhadap model hidraulik fizikal dan menentukan masa yang diambil untuk memasang dan keberkesanan reka bentuk penghadang banjir mudah alih. Kaedah yang dijalankan terbahagi kepada dua fasa iaitu fabrikasi dan ujikaji. Menghasilkan reka bentuk dinding banjir mudah alih termasuk dalam fasa fabrikasi dan modifikasi terhdap NADI1, NADI2 dan NADI3 manakala untuk fasa ujikaji adalah pengambilan data kesan ketinggian air terhadap struktur mekanikal dinding banjir mudah alih. Hasil menunjukkan bahawa NADI3 merupakan struktur paling efektif dan reka bentuk yang paling terbaik untuk menampung tekanan banjir pada ketinggian 1.0m. Kesimpulannya, penghadang banjir yang telah direkacipta mampu mencapai matlamat penggunaan semasa banjir di samping mempunyai mobiliti bagi penggunaan ketika kecemasan. _______________________________________________________________________________________________________ Flood can be defined as high water flows that dominates the natural or artificial banks in any part of the river system. The consequences of flooding may results in losses of lives and asset. Thus giving a negative impact towards social and economic due to high cost in recovery and reduce in investment opportunities in flood prone area. In order to control damage caused by flooding, various devices of flood migitation have been developed over the years. Mobile flood wall barrier (MFWB) is one of the solution in flood mitigation. The objective of this study is to determine water tide flood barrier due to pressure by testing it using a physical hydraulic model and to determine the time taken for installation and effectiveness design of the mobile flood wall barrier. The method for this study are divided into two phase which are physical model fabrication and experimental phase. To meet the objectives this study consist of three concept of mobile flood wall barrier named NADI1, NADI2 and NADI3 which have different mechanism and dimension of flood barrier. Results shows that the structure of NADI3 is the most effective and well designed to withstand flood pressure and flood level of 1.0m. It is concluded that the designed barrier can provide the intended purpose for flood usage while being able to have the mobility for fast execution during emergency times.
