DEVELOPMENT OF WATER-QUALITY MANAGEMENT STRATEGIES FOR THE PROPOSED ISIKLI RESERVOIR

A two-dimensional laterally averaged hydrodynamic and water quality mo del (CE-QUAL-WS) is used to simulate the water quality behavior in the proposed Isikli Reservoir of the Ankara Water Supply System to determ ine appropriate strategies for the management of water quality. Isikli application of the model is used to demonstrate the potential water q uality degradation patterns in the reservoir under different pollution loads. The results of the modeling study are compared with the drinki ng water quality standards currently effective in Turkey to formulate various water quality management strategies for the reservoir and its catchment area. In addition, various treatment options are evaluated c onsidering the existing treatment system of Ankara City. Based on the findings of this study, treatment or interception of wastewaters origi nating from the existing pollution sources around the reservoir area a re introduced as the major infrastructural control techniques. Further , establishment of protection zones around the reservoir and relocatin g the possible pollution sources to a point downstream of the dam axis are found to be the most applicable administrative control methods fo r water quality preservation in the proposed reservoir.
