Water on an urban planet: Urbanization and the reach of urban water infrastructure

Infrastructure Asset Management of Urban Water Systems

IAM methods partially differ from those applicable to managing other types of assets. One of the reasons is the fact that such infrastructures have indefinite lives, in order to satisfy the permanent needs of a specific public service. Infrastructures are not replaceable as a whole, only piecemeal. Consequently, in a mature infrastructure, all phases of assets lifetime coex‐ ist. Additionally, ...

Lost Space Renewal; a Reborn of an Urban Water Body

Due to rapid growth of urbanization and economic demand, we are continuously losing our fields,our free lands, open sky, ponds, lakes; actually our breathing spaces. Sometimes for zoning policies, migration ortransferal of a particular business or activity, a place like waterfronts, body of water, military or industrial sites can lostits importance, kept vacant and become a dead place. These ar...

Evaluating the effect of water harvesting methods on urban runoff (Case study: Birjand urban watershed)

New approaches to urban runoff management seek to reduce the volume and discharge of rainfall peaks as well as the amount of pollutants in urban areas to a level that is reminiscent of rainfall runoff in the decades before urban development. SWMM software is one of the best models to help in this field and it can be used to study the effects of using water harvesting methods on the volume of ru...

Modelling an urban water system on the edge of chaos

Viewing an urban water system as a complex adaptive system provides new opportunities for analysis and avoids some critical simplifications. Taking this perspective, it is possible to explore the interrelated effects of changes to the system. This is particularly important in the developing world where donors providing aid aim to improve conditions but struggle to understand and quantify the sy...
