Adaptation of water distribution networks for urban renewal

Çelik, Mustafa Ertan
Urban renewal managed by Turkish Municipalities and Housing Development $GPLQLVWUDWLRQ 72.ø) causes increase in water consumption at particular nodes. This study aims to find permissible increase in discharge at a single node without affecting other nodes in Yayla neighborhood, which is part of N8.3 pressure zone. Initially, capacity of existing water distribution network should be investigated to determine whether consumption increase at particular nodes affects the system. Peak discharge drawn from N8.3 pressure zone in Ankara is 650 m3/hr. This value can be increased up to 800 m3/hr without adding any pump to the current system. Firstly, network analysis is carried out by using Linear Theory and results are compared with Watercad outputs. Then sensitivity analysis is conducted for the system. At the end of the study, maximum possible outflow at the single node without disturbing other nodes have been obtained as 96.52 m3/hr for Yayla neighborhood. If this discharge is drawn from Yayla, minimum pressure head will be 40 m. To check the accuracy of the method, nodal demand was entered as 96.52 m3/hr for a particular node in Watercad and network analysis was refreshed. After refreshing analysis, Watercad verified the method used in this study. Since minimum pressure head values are 40 m, the value guaranteed by the municipality, a satisfying result has been observed. A methodology is offered to the municipalities for adapting existing lots in the city for urban renewal.


An Institutional analysis of the transformation of informal housing settlements in Turkey : a case study in the Şentepe neighbourhood of Ankara
Özdemirli, Yelda; Türel, Ali; Department of City and Regional Planning (2012)
Transformation of informal housing settlements by urban renewal and redevelopment has become one of the major tasks of Turkish urban policy in the last decades. Nevertheless, in some cases urban redevelopment could not be facilitated due to low level of investments; and moreover most of the transformed settlements are still problematic with added difficulties brought out by urban transformation itself such as lower levels of physical quality, gentrification or dislocation. Understanding the sources of these...
The role of urban agriculture in sustainable urban development, creation of social bonds and community formation
Erişen, Yağmur; Akkar Ercan, Zübeyde Müge; Urban Design in City and Regional Planning Department (2022-4-18)
With the ever-increasing urbanization, sustainable urban development has gained more importance. Actions to achieve sustainable urban development have been discussed from many perspectives. One of the prescribed actions for successful sustainable development is the sustainable communities according to the specific urban context, responding to the wants, needs and the culture of its community. With the COVID-19, people in cities realized the importance of green spaces and the critical need for socialization....
Seismic vulnerabilities and risks for urban mitigation planning in Turkey
Saner, Tugce Sonmez (2015-09-01)
Chronic seismic hazards and resulting secondary impacts as natural conditions of the country, and the loss of robust building and prudent settlement practices as aggravated by rapid population growth make cities the most vulnerable geographical and social entities in Turkey. For the development of risk reduction policies, an essential step is to prioritize settlements according to their vulnerability levels. This could be determined by hazard probabilities and attributes of the building stock of each settle...
Looking at the urban transformation project from the gecekondu dwellers’ perspective: the case of Mamak
Poyraz, Ufuk; Şengül, Hüseyin Tarık; Department of Urban Policy Planning and Local Governments (2011)
The gecekondu settlements emerged as a grassroots solution to the housing problem of migrant population in the lack of effective state intervention. Although most of these settlements gained legal status and title deeds in the following decades, they were still considered to be problem to be solved in due process. Starting from the mid-1980s, as a result of the so-called rehabilitation plans, considerable part of the gecekondu areas underwent a rapid redevelopment process through the market mechanism. The g...
Displacement and asset transformation from inner-city squatter settlement into peripheral mass housing
Borsuk, Imren; Eroglu, Ensari (SAGE Publications, 2020-04-01)
While slum clearance projects in the Global South have displaced a large number of urban poor from the inner city to peripheral areas, peripheral mass housing estates have been developed as a spatial fix to improve the livelihood of the urban poor through slum development projects. Shifting the focus of displacement and poverty studies on changing assets and social experiences of displacement, this study makes an empirical contribution to the literature with a case study from Turkey. It demonstrates that ma...
