GEOG 101 Lecture Notes - Lecture 29: Stormwater, Hydrosphere, Water Resource Management
Document Summary
Urban hydrosphere physical component of an urban ecosystem. Urban development is closely related to the availability and quality of water. Access to water as a resource, but also water as a hazard form constraints for public health, living conditions, food production and economic development in cities. Resource: supply, flushing, cooling, irrigation, power, recreation. Topography: limits to land development, economic pathways. Managing water resources in cities and ensuring water access for multiple uses. 3 goals for integrative water resource management for cities: 1) wisely use water resources such as drinking water supply, flushing, irrigation, power. 2) protect water resources by avoiding chemical and biological contamination, maintain. 3) protect city from excessive water by integrating stormwater management, flood health for humans and ecosystems in city and downstream of city. control, and disaster response. The major physical principles that drive the water cycle are energy (required or released in phase changes, mostly solar radiation) and gravity.
