Sakarya River is the Turkey’s third longest river and the Sakarya watershed covers 8% of the surface area of Turkey. Significant agricultural activities accounts for most of the water withdrawals in the upper Sakarya Watershed. Within the scope of water-food nexus, water efficiency of agricultural irrigation have to be improved to aid sustainable water and agricultural management in the study area. The water potential and water uses were evaluated by Water Evaluation Planning System (WEAP) model in Upper Sakarya Watershed. Model was calibrated with the observed reservoir storage and the streamflow. According to results, agriculture is found to be the main water consumer in the watershed. Agricultural management scenarios considered the efficient use of irrigation water with alterations in the current irrigation techniques and crop patterns. When more efficient irrigation systems and less water-intensive crops were selected, irrigation water use decreases between 5-16% while unmet crop demand decreases between 6-13%.

Modelling and forecasting snowmelt runoff process using the HBV model in the eastern part of Turkey ŞORMAN, ALİ ARDA; ŞENSOY ŞORMAN, AYNUR; Tekeli, A. E.; Sorman, A. Ue.; Akyürek, Sevda Zuhal (Wiley, 2009-03-30) Snowmelt runoff in the mountainous eastern part of Turkey is of great importance as it constitutes 60-70% in volume of the total yearly runoff during spring and early summer months. Therefore, determining the amount and timing of snowmelt runoff especially in the Euphrates basin, where large clams are located, is ail important tusk in order to use the water resources of the country in an optimal manner.
Integrated Watershed Management for Lake Mogan with the focus of Agricultural Diffuse Pollution Özcan, Zeynep; Başkan, O; Düzgün, Hafize Şebnem; Kentel, Elçin; Alp, Emre (2015-09-25) Lake Mogan located 20 km south of Ankara, Turkey has a watershed area of 970 km2, and it is dominated by areas with dry agricultural practices (50%) and graze lands (31%). Intense agricultural activities and fast urbanization rates are the most important factors affecting the water quality in Lake Mogan. There has been several management alternatives suggested to improve the water quality in Lake Mogan. In 2008, the municipality implemented lake augmentation strategy to increase the water level since it dro...
Water Quality Assessment of a Shallow Lake in a Specially Protected Area Lake Mogan Ankara Turkey Kiraz, Melike; Alp, Emre (null; 2015-06-01) Mogan and Eymir Lakes are two shallow lakes, interconnected hydrologically in the close vicinity of Ankara, Turkey. A total of 245 km2 of the total 971.4 km2 watershed is under environmental protection status as ‘‘Go¨lbası Specially Protected Area’’. Potential impacts from extensive agriculture, recreation, incomplete infrastructure and other human activities, such as residential settlements, are discussed with reference to previous and more recent pollution monitoring. Six monitoring stations enabling fol...
Hydrologic Model Component of an Atmospheric-Hydrologic Model-Based Real-Time Flood Forecasting System for the Klzlllrmak River Basin in Turkey Ercan, Ali; Chen, Z. Q. Richard; Ishida, Kei; Ohara, Noriaki; Kavvas, M. Levent; Daǧdeviren, Murat; Selek, Bülent (2016-01-01) Klzlllrmak river, with a drainage area of more than 75,000 km2, is the longest river among the rivers which originate and end in Turkey. A coupled atmospheric-hydrologic model based real-time precipitation and flood forecasting system for Klzlllrmak river basin was developed and became operational recently. This real-time forecasting system utilizes the Global Forecast System (GFS) global numerical weather forecasts as the initial conditions and the boundary conditions for the mesoscale atmospheric model WR...
Evaluation of the best management practices to control agricultural diffuse pollution in lake mogan watershed with swat model Özcan, Zeynep; Alp, Emre; Kentel Erdoğan, Elçin; Department of Environmental Engineering (2016) Lake Mogan which is located in Gölbaşı County, Ankara, Turkey is one of the most important wetlands of Turkey and it was declared as Special Environmental Protection Region in 1990. Total area of semi-arid Lake Mogan watershed is 970 km2 and dry farming is practiced approximately in 40% of the basin. Therefore, agricultural diffuse source pollution is a serious concern in the watershed. In the context of this thesis, the effects of implementation of different agricultural best management practices on sedime...
