Structural Flood Defence Measures and Effects on the Surroundings

Floods are one of the major natural disasters that threaten many human lives and causes significant economic losses globally every year. The aftermath of flood on society depends on the affected country’s economic strength prior to the disaster. The larger the disaster and the smaller the economy, the more significant is the effect. This is clearest seen in developing countries, where weak economies become even weaker afterwards. The research work emphasizes structural Engineering work as measures for flood defence, which include: Levees, Storm sewer system, Storm surge protection works, Spillways, Dyke, Renaturalization and Dams. The influences and drawbacks of these measures were discussed and the enormous advantages of Dam which is the major defence measures analyzed.
