Correction 3D modelling of surface spreading and underground dam groundwater recharge: Egri creek subbasin, Turkey(Springer, 2023) Şahin, Yavuz; Tayfur, GökmenArticle Citation - WoS: 4Citation - Scopus: 53d Modelling of Surface Spreading and Underground Dam Groundwater Recharge: Egri Creek Subbasin, Turkey(Springer, 2023) Şahin, Yavuz; Tayfur, GökmenThis study investigated surface spreading and underground dam recharge methods to replenish groundwater in Turkey's Egri Creek Sub-basin of the Kucuk Menderes River Basin. A three-dimensional numerical model was employed for this purpose. Field and lab data are provided to the model for realistic simulations. Pumping test results were used to determine the aquifer parameters. The laboratory works involved sieve analysis, permeability tests, and porosity and water content prediction. The numerical model's boundary conditions were determined from the geological and hydrogeological characteristics of the study area. Initial conditions were expressed regarding water content and pressure head in the vadose zone. The numerical model was satisfactorily validated by simulating water levels in three different pumping wells in the study area. Seven different scenarios, each having a different pool size, were investigated for the surface spreading recharge method. The results showed that a pool size of 30 x 30 m with a 6-m depth basin was the most optimal choice, raising the groundwater level to about 29.3 m. On the other hand, it was found that an underground dam could raise the levels by an average of 9.5 m, which might not be significant to warrant the construction.Conference Object Importance Of Gördes Dam For Izmir Metropolitan City(İZSU, 2017) Şahin, Yavuz; Tayfur, Gökmen; Baba, AlperIzmir is a metropolitan municipality which is the third the most populated city with 4.223.545people in 2016. Fiftysix percent of the drinking water of İzmir city is provided from groundwater resources. The rest comes from Tahtalı and Balçova Dams. The population and water consumption of the city increase each year. Although Gördes dam in Gediz Graben was constructed in between 1998 and 2004 by the Turkish State Hydraulic Works (DSİ), it could not store the water due to geological problems like leaching. Most recently, these problems were solved and the dam will start storing water. The storage capacity of the dam is 448.46 hm3. It is planned to provide for the annual average of 59.00 hm3 for the domestic uses of İzmir Metropolitan Region and for the irrigation of 14,809 hectares areas in Akhisar Plain.
