Hydrogeology of the reservoirs planned in Lower Zamanti Basin and karst related problems, 1993, Bayari C. Serdar, Gureri Brahim
This study aims to define the karst related problems that may arise during the implementation of three weir and two dam projects planned in the Lower Zamanti Basin. Based on the regional hydrogeological investi-gations, the problems that may arise during the construction phase were outlined and relevant investigation techniques were proposed. This study showed that no water leakage problem is expected in the reservoir areas of Çamlıca II , Çamlıca III, Tatlar weirs and Göktaş dam, while the possibility of leakage thorugh the reservoir of the Topraktaş dam should be investigated by means of geophysical surveys and exploratory boreholes. The same suggestions are also valid for the energy tunnels of Çamlıca II, Tatlar weirs and Göktaş dam where dewatering of karst groundwater would be an important problem.

Use of hydrologic, hydrochemical and isotopic data in identification of groundwater flow patterns in Lower Zamantı Basin (Eastern Taurids-Turkey), 1993, Bayari Celal Serdar, Gurer Ibrahim
In karst basins where hydraulic structures ARE designed to utilize the existing water potential, determination of the distinct groundwater flow patterns and the inter-relations among them bears great importance from the view point of the geotechnical safety of the structure. The combined use of hydrologic, hydrochemical and isotopic data enables us to identify different groundwater flow patterns prevailing in karst basins. Once the inter-relation among the groundwater flow patterns is established, the decision regarding the implementation of projects will be easier. Hydrologic investigations including analyses of the "stream yield" and "groundwater balance", produce invaluable information that can be used to locate the important karstic effluents along the basin. The study of the hydrochemistry of major karstic effluents reveals reliable information on the "depth" of underground circulation and the "recharge conditions" dominating within the karst system. Evaluation of environmental isotopic data introduces important details pertaining to the "mean recharge area elevations" and "turn-over times" of the karst waters and inter-relation among each other. Sometimes very closely located karstic outflows may have quite different circulation/recharge characteristics. This paper attempts to demonstrate the combined use of hydrologic, hydrochemical and isotopic techniques for the determination of the "deep-regional" and "shallow" groundwater circulation patterns existing in the Lower Zamanti Basin.

A rare landform: Yerkopru travertine bridges in the Taurids Karst Range, Turkey, 2002, Bayari Cs,
Two examples of travertine bridges are observed at 8 to 15 in above stream level in the Lower Zamanti Basin, Eastern Taurids, Turkey. Yerkopu-1 and Yerkopru-2 bridges are currently being deposited front cool karstic groundwaters with log P-CO2 > 10(-2) atm. The surface area and the total volume of travertine in Yerkopru-1 bridge are 4350 m(2) and 40 000 m(3), whereas the values for Yerkopru-2 are 2250 m(2) and 20000 m(3), respectively. The interplay of hydrogeological Structure, local topography, calcite-saturated hanging springs, algal activity and rapid downcutting in the streambed appear to have led to the formation of travertine bridges. Aeration through cascades and algal uptake causes efficient carbon dioxide evasion that enhances travertine formation. Algal curtains aid lateral development of travertine rims across the stream. Model calculations based on a hypothetical deposit in the form of a half-pyramid implied that lateral development should have occurred from both banks of the stream in the Yerkopru-1 bridge, whereas one-sided growth has been sufficient for Yerkopru-2. The height difference between travertine springs and the main strearn appears to be a result of Pleistocene glaciation during which karstic base-level lowering was either stopped or slowed down while downcutting in the main strearn continued.
