Assessment of Diyarbaklr Basalt Aquifer Hydrogeological Analyzed and Obtains Thematic Maps with GIS Geostatistical Analyst Tool

Diyarbaklr basalt aquifer is volcanic-rock aquifers which contain high quality water. 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.

Obtain Thematic Maps of Diyarbakir Basalt Aquifer＇s Water Quality Parameters with Using GIS Technique

In this study, groundwater quality and water features of Diyarbakir urban basalt aquifer which contains Baglar, Kayapmar, Sur and Yenisehir residential areas aimed to be determined. 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.

Traditional manufacturing of clay brick used in the historical buildings of Diyarbakir （Turkey）

Clay brick is the most common construction materia（ used in the historical buildings of Diyarbaklr （Turkey）. Many clay brick manufacturing workshops and numerous brick masters have emerged. Diyarbakir currently has two clay brick workshops that face the problem of being closed down. Therefore, manufacturing of clay brick by traditional methods may be forgotten in Diyarbakir. This study investigates the manufacturing phases of traditional clay bricks in Diyarbakir＇s local workshops, which have not been documented. The manufacturin8 phases of the clay bricks in Diyarbaklr were examined for the first time based on in-situ observations, investigations, and interviews. The research indicated the general phases of clay brick manufacturing. Raw materials are first prepared, formed, and dried. The firing of clay bricks is then performed through hacking, heating, burning, coolins, and de-hacking. The clay bricks are finally packaged and dispatched. The traditional manufacturing of clay brick methods in Diyarbaklr is similar in many regions of the world. The clay bricks are currently and extensfvely used in the restoration of historic structures. Therefore, their production must be continuous.
