Floods are one of the most common natural disasters in whole world. Solving such problems has largely been addressed by regulating watercourses and constructing embankments as preventive measurse, and by undertaking various operational measures such as placing water barriers in emergency situations. Today, we see that these measures are not enough because the floods are more and more frequent and as such, human life, animals and property are at risk. As technology in protection and rescue progresses, some progress has also been made in the flood defense. There are a number of such defensive measures that are still unknown to us and are simpler and more effective than the example of water dams built from sandbags for with a great number of people and techniques are needed. However, all these defensive measures carry with them their advantages and disadvantages. With the goal of faster and more efficient implementation of flood protection measures, the construction of water barriers in emergency situation respectively, new type of water barriers were discovered that should facilitate and speed up the crisis situation arising in particular area. More about these new methods of flood protection will be shown in this work.
