Effective management of water resources requires understanding and quantification of interaction between groundwater and surface water bodies. The exchange processes have recently received increasing attention because also they have important influences on ecological status of watersheds. The purpose of this study was to characterize the interaction between surface water - groundwater in Kirmir stream - a controlled stream nearby Kızılcahamam, Ankara, Turkey. At the first stage, stream reaches with interaction of groundwater – surface water potential were identified using geological information. Then, thermal remote sensing was utilized to further pinpoint the potential locations in which interaction could occur at a smaller scale. Nested piezometers were installed in identified locations to observe the variations in vertical hydraulic gradient over time. Discharge measurements were performed to understand the gains and losses in stream discharge. Streambed temperature measurements were taken at two different depths for a period of time using temperature loggers to calculate the vertical fluid fluxes through the streambed at various locations. Basic water quality field parameters (temperature, electrical conductivity, total dissolved solid amount, dissolved oxygen, pH and oxidation - reduction potential) were measured. Water samples were taken from both stream and piezometers and these samples were analyzed for major anion concentrations. Chloride mass balance was performed to find the contribution of groundwater and chloride concentrations were associated with the geology of the area. This hierarchical, multi-scale methodology provided an efficient and effective way to determine the locations and the direction of groundwater and surface water exchange processes within the study area

Understanding Groundwater And Surface Waterexchange Processes Along A Controlled Stream Using Thermal Remote Sensing And in Situ Measurements
Varlı, Dilge; Yılmaz, Koray Kamil (2016-12-16)
Effective management of water resources requires understanding and quantification of interaction between groundwater and surface water bodies. Moreover, the exchange processes have recently received increasing attention due to important influences on biogeochemical and ecological status of watersheds. In this study we investigated the exchange processes between surface water and groundwater along Kirmir stream - a controlled stream nearby Kizilcahamam, Ankara, Turkey. At the first stage, potential stream re...
Determination of potential groundwater discharge zones into a Salt Lake using remote sensing techniques and in situ measurements
Kılıç, Ecenur; Yılmaz, Koray Kamil; Süzen, Mehmet Lütfi (2015-04-17)
Groundwater and surface water are integral components of the hydrologic system with strong feedback mechanisms and hence should be treated as a single resource. Existence of groundwater discharge into lakes is a very significant factor that affects both the water quantity of the lake as well as its ecological and biological diversity. The degree of interaction is more significant for shallow lakes because of their increased vulnerability due to limited volume and rapid changes in the extent and duration of ...
Characterization of Groundwater and Surface Water Interactions Along Kirmir Stream Using Field Measurements and Thermal Remote Sensing
Varlı, Dilge; Yılmaz, Koray Kamil; Süzen, Mehmet Lütfi (null; 2015-04-10)
he exchange processes between surface water and groundwater have recently received attention due to the important implications on the basin-scale water management as well as biogeochemical and ecological status of watersheds. We investigated the exchange processes between Kirmir Stream - a controlled stream nearby the city of Ankara, Turkey - and groundwater using a hierarchical multi-scale approach incorporating catchment physical characteristics (geology, geomorphology, DEM etc.), water quality field para...
Optimization of Multireservoir Systems by Genetic Algorithm
Hinçal, Onur; Altan Sakarya, Ayşe Burcu; Ger, A. Metin (2011-03-01)
Application of optimization techniques for determining the optimal operating policy of reservoirs is a major issue in water resources planning and management. As an optimization Genetic Algorithm, ruled by evolution techniques, have become popular in diversified fields of science. The main aim of this study is to explore the efficiency and effectiveness of genetic algorithm in optimization of multi-reservoirs. A computer code has been constructed for this purpose and verified by means of a reference problem...
CHARACTERIZATION OF GROUNDWATER AND SURFACE WATER INTERACTIONS USING THERMAL REMOTE SENSING AND IN-STREAM MEASUREMENTS
Yılmaz, Koray Kamil(2015-12-31)
Surface water and groundwater interact in a dynamic and complex way in variety of hydrologic settings. Hence identification and quantification of exchange processes between surface water and groundwater is essential for developing sustainable water resources management plans, understanding dominant hydrologic processes and identifying geological controls. The objective of this study is to integrate high resolution maps of airborne remotely sensed stream surface temperature measurements with a set of in-stre...
