Synopsis
“Water” is the primary requirement of life on earth. Even though three quarters of our planet is covered with water, the amount of fresh water that people can use is only 0.0002% of the total amount of water. Due to global warming and climate change, precipitation regimes are changing. Some parts of the world are struggling with drought and some parts are struggling with floods. Population growth, urbanization and human activities increase the demand pressure on usable freshwater resources, while existing water resources become unusable due to polluting factors. Water crises are becoming more and more threatening to humanity and other environmental components with each passing day. With the advancement of science and technology, people once had the ability to bring water to every settlement, but now it has been discussed whether there is a water source that can be taken in today's world. The only solution that emerged as a result of these discussions is to manage the water in its own basin and to shape the settlements within the scope of the sustainability of the existing water resources. While scientific research shows the effects of land use on water resources and water consumption, water-oriented studies have started to gain importance in urban planning processes. In this study, measures that can be taken with urban planning studies are listed against the water crisis and drought process, which have become an important problem in the world and in our country. While the issues to be considered in the design of urban functions such as housing, industry, transportation networks and green areas that make, suggestions are made about water sensitive planning processes from upper scales to lower scales. Within the scope of the study, scientific research on water sensitive planning studies were taken as a basis, and a water sensitive planning process was described in the country planning scale and regional scale to the neighborhood scale.
