Türkiye Jeoloji Kurultayı, 06-10 Nisan 2015, Ankaraİzmir’in batı ucunda yer alan Karaburun Yarımadası turizm açısından Türkiye’nin en önemli yerlerinden bir tanesidir. Yerli ve yabancı turistlerin Çeşme ve Alaçatı’da yer alan turizm tesislerinde konaklamalarının yanı sıra, bu kesimlerde yer alan ikinci konutlar nedeni ile de yaz ayları nüfusunu çok arttırdığı görülmektedir. 2012 yılı verilerine göre Çeşme ilçe nüfusu 34563 kişi olarak görülmekle birlikte, özellikle 2014 Temmuz ve Ağustos aylarında nüfusun altı yüz bin kişiye ulaştığı vurgulanmaktadır. Bu nedenle, İlçenin en önemli sorunu su olmuştur. Çeşme ilçesinin su ihtiyacı, Alaçatı Barajı ve Karaburun Yarımadası’nın güney batısında yer alan Ildır Bölgesi’ndeki kuyulardan sağlanmaktadır. İklim değişiminin bir sonucu olarak son yıllarda, barajdaki su seviyesi çok azalmıştır. Buna ek olarak, alandaki yeraltısuyu kaynakları da aşırı çekimin bir sonucu olarak tuzlanmaya başlamıştır. Çeşme’nin başlıca su kaynağını oluşturan, Ildı...

The intermittent creek receives domestic and industrial discharges of Kemalpaşa District Center and its neighborhoods and more than 180 factories of the organized industrial zone. A monitoring campaign was conducted on the creek and samples were taken in two different seasons with distinct hydrological characteristics from 20 stations along the creek to quantify the quality status of water and sediment columns. A number of physicochemical parameters, heavy metals, and trace elements were measured by field and laboratory techniques to assess the status of creek's water and sediment quality. The spatial and temporal variations were determined, and statistical tools were used to conduct an environmental forensic overview along the creek. A geo-accumulation index and a modified heavy metal pollution index were calculated to cumulatively assess the quali...

After the accident, various topics have been discussed to evaluate the details of occurrence of the event and to understand its impacts on human, animal and plant life. One of the most controversial topics is the release height and homogeneity of radionuclides at release point in the atmosphere. Currently, there exists no definitive decision on the release height and vertical distribution pattern of radionuclides released from the Chernobyl accident. Based on this premise, this study focuses on the analysis of various possible release patterns along the vertical dimension and the potential influences on the atmospheric dispersion and total deposition with particular reference to 137Cs. For this purpose, some release pattern functions following uniform, Dirac delta, exponential, log-Pearson type III, and cumulative distribution functions along the z-axis were used to simulate the dispersion of 137Cs released from the accident site. A total of 22 release patterns are produced using different maximum release heights (2000, 3000, and 4000 m). A Lagrangian particle dispersion model, FLEXPART, was then used to conduct simulations for these conditions to assess most coherent dispersion and deposition patterns. Model results from each release function were plotted, compared with each other and verified with measured data. In the functions where the release predominantly existed at lower levels, more extreme values were observed in the close vicinity of the source. Consequently, Dirac delta, log-Pearson type III (1), and exponential functions can be used as worst-case conditions at local scale. On the other hand, simulations also revealed that contamination spread to wider areas in cases where the release occurred from higher levels of the atmosphere. Therefore, log-Pearson type III (2) and cumulative distribution function can be considered more significant concerning a wider distribution of affected areas.
