Development of urbanization and the natural and artificial changes in land use and environments has been called urban watersheds.
It has been created with different hydrological and hydrologic behaviors that designed and managed the sustainable management and utilization of water resources in urban areas to rebuild the degradation of nature through urban development.
Ecological impairment and flooding caused by urbanization can be expressed numerically by calculating the risks throughout the watershed and along the main stems of the streams. The risks can be evaluated in terms of the present and/or future.
Participatory approach is necessary for the urban watershed management because people and multiple authorities are responcible for the urbanization.
Main objective of a sustainable urban watershed management system are to provide safe drinking water, handle wastewater for the maintenance of public health, protect against floods, along with alleviating the effects of pollution.
