It was main resources for Diyarbaklr city center drinking supply up to 2005. Somewhere, basalt aquifer groundwater is still used for irrigation in rural areas of Diyarbaklr city. In the study, Diyarbaklr city center＇s （which is located on the Tigris river basin） basalt aquifer groundwater potentials and hydrogeological features are examined and modeled by using GIS programmer. Firstly, general geological data, meteorological data and general information about natural water sources are collected together, afterwards, logs of well drilled by public institutions and private individuals within the Diyarbaklr city center are analyzed. Static water level, dynamic water level and well pumps yields are classified in these logs. Then, thematic maps produced with the help of Arc Info Professional GIS programmer with geostatistical analyst tool. Groundwater source potential of Diyarbaktr is examined by means of these thematic maps. In hydrogeological research, productivity by aquifer features, water retention capacity and groundwater level data evaluated with geological structure of area are taken into consideration.展开更多

At this location, water wells opened for drinking water and irrigation water are used in the agricultural field. Therefore, in the study area, which opened in water samples taken from water wells were examined. It was reformed in the field, water samples were taken from the predrilled water wells. Water wells in the same coordinates are determined by Garmin etrex 30 handheld GPS system. Chemical analysis of water samples taken in the laboratory was made. The wells water＇s pH, Electrical Conductivity （EC） and Dissolved Solids （TDS） features were acquired by Portable Hanna HI 98125 pH/EC/TDS/℃ meter device at the field. At this study, basalt aquifer features are considered, and water quality and water chemical properties were determined in Diyarbakir city centre, pH, EC and TDS values of the water samples taken on site and those water chemical analyses were measured in the laboratory. Then, they were modelled by using ARC INFO 10.2.1 GIS programme and geostatistical analyst extension tool. At the end of this process, thematic map of Diyarbakir＇s basalt aquifer pH, EC and TDS were produced.展开更多

To evaluate the possible maximum response of SSLW to climate change, the combination of the conditional nonlinear optimal perturbation related to the parameter(CNOP-P) approach and projections from 10 general circulation models(GCMs) of the Coupled Model Intercomparison Project5(CMIP5) are used. The CNOP-P-type temperature change scenario, a new type of temperature change scenario, is determined by using the CNOP-P method and constrained by the temperature change projections from the 10 GCMs under a high-emission scenario(the Representative Concentration Pathway 8.5 scenario). Numerical results have shown that the response of SSLW to the CNOP-P-type temperature scenario is stronger than those to the 11 temperature scenarios derived from the 10 GCMs and from their ensemble average in the entire ‘3H' region. In the northern region, SSLW under the CNOP-P-type scenario increases to0.1773 m^3 m^(-3); however, SSLW in the scenarios from the GCMs fluctuates from 0.1671 to 0.1748 m^3 m^(-3). In the southern region,SSLW decreases, and its variation(–0.0070 m^3 m^(-3)) due to the CNOP-P-type scenario is higher than each of the variations(–0.0051 to –0.0026 m^3 m^(-3)) due to the scenarios from the GCMs.展开更多
