New trends and utilisation of materials in protection against flood

Abstract

The climate change is causing changes in the environment. Drought periods are beginning to alternate with the period of major floods in recent times. The paper deals with principles of active flood control protection. Authors tried to give an information about new trends in flood protection by showing on new methods and new possibilities against flood and damage of men properties. The growing production and utilization of various materials, mainly plastics are enormous in the last period. Plastics have excellent mechanical properties, are light and in many cases replace metals. The volume of plastic waste is growing up, therefore it is necessary to determine how to solve the processing of plastic waste. In early studies were noted the methods of plastics recycling, whereas, the problem of utilisation of these plastics is much more complicated. From the plastic waste as the semi-products can be prepared the plastic plates, boards, foils. The contribution also deals with the testing of materials properties of recycled plastics produced by extruding and it shows the utilisation of produced plastics plates in engineering practice and environment. River floods are the most common natural disaster in Europe and world, too, and flood damage is expected to increase in the next decades. The purpose of current work was an experimental study of utilisation of plastic recycled materials, testing of their mechanical properties and their utilisation in specific conditions as flood barriers. The methods of experimental investigation and data processing have developed on a practical basis.
