    An Evaluation of the Environmental Problems of Burdur Lake Basin
    (Erciyes Üniversitesi Fen Bilimleri Enstitüsü Fen Bilimleri Dergisi, 2023) Soylu, Mehmet; Dadaşer Çelik, Filiz; Kaçıkoç, Meltem
    Burdur Lake is a closed-basin lake, located in the Mediterranean region of Türkiye. In this study, the studies conducted in the Burdur Lake and Burdur Lake Basin were examined in an attempt to determine major environmental problems in the region. Research directions for solving environmental problems were also evaluated. This study examined 150 studies published between 1976 and 2022. The studies were classified into seven categories based on the research topics: Biodiversity/Ecology, Hydrology/Hydrological Change, Land Cover Change, Water Quality, Climate Change, Socio-Economic Impact, Environmental Policies/Recreation. Majority of the studies were related to Biodiversity/Ecology topic. This was followed by the Hydrology/Hydrological Change and Environmental Policies/Recreation studies. There is a consensus that the major threat toward Burdur Lake is the alteration of its flow regime. Ecological and land cover changes were also mentioned. The number of studies about Burdur Lake has increased rapidly in the last ten years. The increase in environmental problems in the Burdur Lake is most probably responsible for this trend. Climate change, which can be among the future pressure factors for Burdur Lake, has not received sufficient attention yet. We recommend that the future studies consider climate change effects on the hydrologic and ecological system.

    Climate Change Impacts on Potential Groundwater Recharge in the Palas Basin, Turkey
    (EJENS (European Journal of Engineering and Natural Sciences), 2022) Soylu, Mehmet; Dadaşer Çelik, Filiz
    Climate change poses a major threat for sustainability of groundwater resources. In this study, we aimed to determine how climate change can affect groundwater recharge potential in the Palas Basin. Palas Basin is a semi-arid closed basin located in Kayseri, in the central Anatolia region of Turkey. Agriculture is the major economic activity in the region and groundwater is used extensively for irrigation purposes. In this study, we estimated potential groundwater recharge for the Palas Basin under two representative concentration pathway (RCP) scenarios (RCP4.5 and RCP8.5) projected by the HadGEM2-ES, MPI-ESM-MR, GFDL-ESM2M global climate models. All models projected a decrease in mean annual potential groundwater recharge under the RCP8.5 scenario. Under the RCP4.5 scenario, the trends in annual potential groundwater recharge were downward according to the HadGEM2-ES and MPIESM-MR models but slightly positive according to the GFDL-ESM2M model. For the sustainability of groundwater system and agricultural activities in the basin, climate change adaptation strategies should be developed for the agricultural sector.

    Groundwater Vulnerability Mapping Using DRASTIC Model: A Case Study at the Palas Basin in Turkey
    (EJENS (European Journal of Engineering and Natural Sciences), 2022) Bozdoganlio, Uğur; Soylu, Mehmet; Dadaşer Çelik, Filiz
    The study aims to estimate groundwater vulnerability against pollution at the Palas Basin (Turkey) by using geographical information system based DRASTIC model. A DRASTIC model integrates information for seven hydrogeological parameters: depth to water (D), net recharge (R), aquifer media (A), soil media (S), topography (T), impact of vadose zone (I), and hydraulic conductivity (C), and identifies spatial vulnerability. The study area, Palas Basin, is a hydrologically closed, agricultural basin, where groundwater is used for meeting irrigation and municipal water requirements. Seven hydrogeological parameters were combined to classify the basin into three vulnerable zones (as low, moderate, and high). The central part of the basin was identified to be highly vulnerable, while the eastern and southern parts were characterized by moderate to low vulnerable areas. Intensive agricultural activities, widespread in the central basin, create high pollution potential. This study showed that the DRASTIC approach provided a simple and efficient tool for evaluating groundwater vulnerability. The results can be used by water managers in groundwater management in the Palas Basin.

    The Use of Modified Drastic Method (DRASTIC-LU) for Assessment of Groundwater Vulnerability to Pollution at the Palas Basin/Turkey
    (Springer, 2022) Soylu, Mehmet; Bozdoganlio, Uğur; Dadaşer Çelik, Filiz
    Groundwater is one of our major water resources, which is affected by hydrological, climatic, and anthropogenic factors. DRASTIC model is a widelyused index-based method that can be used to evaluate the vulnerability of the groundwater systems to pollution. DRASTIC uses depth to water (D), net recharge (R), aquifer media (A), soil media (S), topography (T), impact of vadose zone (I), and hydraulic conductivity (C) information to create a GIS-based vulnerability map. In this study, we used a modified version of DRASTIC model (DRASTICLU) for vulnerability assessment at the Palas Basin/Turkey. DRASTIC-LU uses land use (LU) information in addition to the hydrogeological parameters. The measured nitrate concentrations in the Palas Basin were used to test the original and modified DRASTIC models. The results of the study revealed that the DRASTICLU improved predictions of nitrate concentrations. The results of the vulnerability assessment in this study can be used for groundwater management and planning at the Palas Basin.
