Water resources assessment for city area

Abstract

Many cities face problem scarcity of fresh and clean water now. However, our ability to correctly assess and predict city water availability, use and balance is still quite limited. City-water model is developed and used to assess water resources using system dynamics approach. It has shown that: (a) For economic growth scenarios, there is a strong relationship between the water resources and future industrial growth, and (b) In the existing condition of industries in Indonesia, cities the water pollution is the most important future water issue on the global level. Solutions for water problems are at the city level and the regional presented in this paper. City and regional characteristics of the water resources considerable increase in the complexity of the model. First results indicate that City-water model has a potential to identify water-related issues of domestic priority and assist policy makers in evaluating various sustainable solutions for sustainable water resources management.
