Around the world, aquifer water quality is deteriorating. The hydrology of drainage basins is dramatically influenced by the urbanization process, which leads to a relative increase in impervious surfaces. This increases the amount of stormwater runoff and decreases the amount of rainwater that can infiltrate into the groundwater. At the same time, as a result of urbanization, there is an increase in water demand and a greater need to efficiently remove runoff from the city (in order to prevent flooding).
Climate change has a significant influence of the planning of a water supply system, since it changes the amount and frequency of rainfall, and it increases the frequency of extreme climate events, such as severe rainstorms or years of drought. In addition, climate change can directly and indirectly lead to natural disasters, affect water availability and cause a rise in sea level.
Goals and Objectives of the Development of the Vision of Water Sensitive Cities in Israel
The goal of this sub-project is to develop a comprehensive vision for water sensitive cities in Israel that considers scientific, economic and social aspects. The research is based on a meta-analysis of current knowledge relating to our goal, for example: possible influences of global warming; population increase and water demand; rates of urbanization and the characteristics of future urban spaces; and stormwater harvesting for reuse or for recharge to the aquifer. The research also investigates public acceptance of a water sensitive city, as well as barriers to introducing alternative urban water source, as well as possible institutional incentives.
