Rehabilitation of water supply systems
Toğrul, Nevzat; Merzi, Nuri; Department of Civil Engineering (2015)
Management of water supply systems by an economic and efficient way is a significant issue for water authorities. Selection and operation of water supply elements appropriately to satisfy water need affects the energy consumption of the system. This study aims to constitute a long term rehabilitation plan for water supply elements (only storage tanks, pumps and transmission line pipes are in the scope of the study). A case study has been performed on N8.3 pressure zone of Ankara water distribution network. ...
The European Union water framework directive and Turkey‟s water management policy : an analysis
Sümer, Vakur; Güneş, Şule; Department of International Relations (2011)
This thesis focuses on the relationship with the EU Water Framework Directive (WFD) and Turkey‟s water management policy. The aim of the thesis is to understand and analyze impacts of Water Framework Directive on different dimensions of Turkey‟s water management policy. This thesis argues that legal discourses, organizations and policy networks prevailing in Turkey‟s water management policy are more flexible in terms of change, whereas institutional arrangements, which constitute the substantive part of the...
Automated calibration of water distribution networks
Apaydın, Öncü; Merzi, Nuri; Department of Civil Engineering (2013)
Water distribution network models are widely used for various purposes such as long-range planning, design, operation and water quality management. Before these models are used for a specific study, they should be calibrated by adjusting model parameters such as pipe roughness values and nodal demands so that models can yield compatible results with site observations (basically, pressure readings). Many methods have been developed to calibrate water distribution networks. In this study, Darwin Calibrator, a...
Investigation of non-point source pollution potential in the watershed of porsuk dam reservoir
Küçük, Elif; Aksoy, Ayşegül; Department of Environmental Engineering (2013)
The achievement of good water quality status depends not only on point source control, but also on minimizing the contribution of non-point sources on pollution. Although non-point source pollution includes numerous components, agriculture has been considered as the primary activity responsible from deterioration in the quality of water resources. In this thesis, a hypothetical assessment was conducted to assess the relative impacts of different agricultural practices on the Watershed of the Porsuk Dam Rese...
Determination of chlorophyll-a distribution in Lake Eymir using regression and artificial neural network models with hybrid inputs
Yüzügüllü, Onur; Aksoy, Ayşegül; Department of Environmental Engineering (2011)
Chlorophyll-a is a parameter which can be used to understand the trophic state of water bodies. Therefore, monitoring of this parameter is required. Yet, distribution of chlorophyll-a in water bodies is not homogeneous and exhibits both spatial and temporal variations. Therefore, frequent sampling and high sample sizes are needed for the determination of chlorophyll-a quantities. This would in return increase the sampling costs and labor requirement, especially if the topography makes the location hard to r...
