This paper presents a study of water management in Istanbul, a megacity with a population of 11.5 million. The population of Istanbul grew at almost twice the overall rate of the whole of Turkey because of a large in-migration. The projected water demand was underestimated and Istanbul experienced severe water shortages in the early 1990s. During the last decade US$ 3.6 billion of investments were made to improve and expand water and wastewater systems. Several large-scale water transmission projects were started. The percentage of treated wastewater increased from 10% to 95% within the same period. The unaccounted-for water rate has been reduced from 50% to 34%. Environmental protection measures have been put into effect to protect the watersheds of the water reservoirs. The 2002 Metropolis Award Winner Golden Horn Environment Protection Project is another example of environmental rehabilitation efforts undertaken in Istanbul.

Climate change impacts on meteorological drought using SPI and SPEI: case study of Ankara, Turkey MEHR, ALI DANANDEH; Sorman, Ali Unal; Kahya, Ercan; Afshar, Mahdı Hesamı (Informa UK Limited, 2019-11-27) Using regionally downscaled and adjusted outputs of three global climate models (GCMs), meteorological drought analysis was accomplished across Ankara, the capital city of Turkey. To this end, standardized precipitation index (SPI) and standardized precipitation evapotranspiration index (SPEI) were projected under (representative concentration pathway) RCP4.5 and RCP8.5 greenhouse gas scenarios. In general, our results show that Ankara experienced six severe and two extreme drought events during the referen...
Alternative solutions for long missing streamflow data for sustainable water resources management Mesta, Buket; Akgün, Ömer Burak; Kentel Erdoğan, Elçin (Informa UK Limited, 2020-08-01) Sustainable water resources management requires long time series of streamflow data. In this study, a Takagi-Sugeno fuzzy rule-based (FRB) model is developed to reconstruct long periods of missing daily streamflow data which is a common problem in developing countries. The FRB model uses observations of neighbouring stream gauges, and thus is advantageous regarding data and time requirement compared to physical models. With the proper set of inputs, the FRB model provides better estimates than the hydrologi...
Estimation of river flow by artificial neural networks and identification of input vectors susceptible to producing unreliable flow estimates Kentel Erdoğan, Elçin (Elsevier BV, 2009-09-15) Reliable river flow estimates are crucial for appropriate water resources planning and management. River flow forecasting can be conducted by conceptual or physical models, or data-driven black box models. Development of physically-based models requires an understanding of ail the physical processes which impact a natural process and the interactions among them. Since identification of the relationships among these physical processes is very difficult, data-driven approaches have recently been utilized in h...
Development of a Safety-Inspection Method for River Bridges in Turkey Akay, Huseyin; Kocyigit, Musteyde Baduna; Yanmaz, Ali Melih (MDPI AG, 2019-09-01) In this paper, findings of a research project about river bridges in Turkey are shared and details of the developed safety-inspection method based on hydrological and hydraulic factors are presented. In the project, the Western Black Sea Basin was chosen as the pilot area, where the basin is mountainous with steep slopes and has a rainy climate with frequent flash floods. Many river bridges in the basin were inspected at different flow conditions throughout the project duration of three years. The developed...
Accuracy assessment of MODIS daily snow albedo retrievals with in situ measurements in Karasu basin, Turkey Tekeli, AE; Sensoy, A; Sorman, A; Akyürek, Sevda Zuhal; Sorman, U (Wiley, 2006-03-15) Over the ablation period of 2004, daily snow albedo values retrieved from the moderate-resolution imaging spectroradiometer (MODIS) Terra were compared with ground-based albedo measurements. Two data sets are used for this study. The first data set is from two automatic weather stations (AWS) located at fixed points in Karasu basin in eastern Turkey. This provided the temporal assessment of MODIS daily snow albedo values. The second data set, consisting of 19 observation points randomly distributed around o...
