METHODS AND DESIGNS THAT CAN BE USED TO KEEP RAINWATER FROM FLOWING INTO THE URBAN AREA

Abstract: Non-infrastructure or inadequate,increase of technically unplanned constructions and the acceleration of population growth lead to distorted urbanization. One of the most important problems of this formation is the rainwaters. Rainwaters also affect buildings, roads, parking lots and landscapes that are thought to be well planned except for distorted urbanization. These structures, which are not considered rainwater or poorly designed, with a certain amount of rainfall, the water flows without leaking into the lower layers, and it is inevitable to turn into a flood in urban areas by increasing the flow. This flow also causes erosion by eroding the upper part of the soil layer in the landscapes of the urban area. Rainwaters are required to be kept and collected in urban areas without causing effects such as flooding, floods and erosion. It is also important for these rainwater to be presented to beneficial uses and is an advantage. This study aims at explaining the ways in which rainwater can be kept in the urban areas such as roads and parking lots without passing to the stream, reducing the harmful effects and provide benefits to the environment, and examining the existing designs.
