However, existing methods and the outcomes obtained via these methods are continuously criticized and do not meet the expectations in terms of reliability. On the other hand, increasing need to plan water resources and lack of alternative methods to determine the water potential in areas where flow measurement does not exist make it impossible to evade dependency on these methods. With this purpose generated flexible, comprehensive and reliable runoff distribution map was formed on the basis of weighted overlay in parallel to impact degrees of effective parameters. The calibration of the obtained map was done on the basis of pixels based on both theoretical and empirical data. As a result of the analyses, it was seen that an accurate runoff distribution model that fully reflects the characteristics of the field can only be developed by calibrating it based on the real flow data obtained from remote sub-basins that are free from external interventions. It would be impossible to free the theoretical approaches from errors since these approaches are related to amount of water which has an active nature and interacts with factors that are beyond measure. As a result of implementing the method on Ergene River Basin, the sample basin, a surface runoff volume of an average183,45mm/year/m², i.e. a total of 2100000000m³/year ±2% was obtained for the basin and this result has at least 27% difference from the results obtained with existing methods.","PeriodicalId":224531,"journal":{"name":"Turkish Journal of Water Science and Management","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114517396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study showed that 100% of wastewater was not be treated because of lack of wastewater treatment plants. There was no water distribution network and also 91% of the people in the community has not accessed to the public water network. The water-supply infrastructure was not efficient. Therefore, all water-supply infrastructure in Daret Azza subdistrict was needed to rehabilitate and maintenance . The people of Daret Azza subdistrict spent about 8-13% of their income for purchasing unsafe water while the people living in the Regime-controlled areas spent about 0.5-1% of their income for purchasing safe water. For this reason, the people of Non-State Armed Group controlled areas needed urgent and sustainable technical and financial supports, especially for obtaining potable water.","PeriodicalId":224531,"journal":{"name":"Turkish Journal of Water Science and Management","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121075281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodologies developed in this manner were implemented in the Gediz River Basin in Turkey. A total of 76 groundwater bodies delineated in the Basin were subjected to characterization, where the anthropogenic pressures on the quality and quantity of groundwater and their possible impacts were determined. Detailed risk analysis done by the available data revealed to the groundwater bodies which were under risk of achieving good status in terms of quality and/or quantity. In order to disclose the current status of all groundwater bodies, in-depth analyses (establishing threshold values, comparison of the measured values to the threshold values/quality standards, water budget calculations, etc.) were performed and supported by the comprehensive field investigations and monitoring. Ultimate results indicated that 33 groundwater bodies out of 76 were in poor status; and hence, all these bodies should be included in the programme of measures. Moreover, all the monitoring points at which the threshold values and/or quality standards are exceeded were also included in the programme of measures. Finally, the required measures to be taken in the Gediz River Basin at different scales (basin, groundwater body and monitoring point); to improve the poor status or to conserve the good status of groundwater, were pointed out considering both its quality and quantity.","PeriodicalId":224531,"journal":{"name":"Turkish Journal of Water Science and Management","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124632209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, numerous hydromorphological assessment methods have been developed worldwide including Europe after the Water Framework Directive came into force. Turkey, as a European Union candidate country, has started to implement the Directive and has made some progress. In this context, Turkey needs to develop a national hydromorphological assessment method compliant with the. Two of Multi Criteria Decision Making (methods, which are Analytical Hierarchy Process and Simple Additive Weighting were applied to find the most suitable hydromorphological assessment method for Turkey. For this aim, we reviewed 25 non-European methods and 19 European methods, and determined the Slovenian method and the South African method as the most convenient ones.","PeriodicalId":224531,"journal":{"name":"Turkish Journal of Water Science and Management","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126208403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
