In this research, four different groups (G1: Soil-Cocopeat, G2: Soil-Loofah, G3: Soil-Perlite and G4: Soil) were created according to the plant growing media used in the planting layer. The researchers conducted measurements of the drained irrigation water’s EC (Electrical Conductivity) value, pH value and drainage amount, the plant growing media’s temperature and moisture, the plant’s height and leaf number, and the amount of subsidence in the planting layer. In line with the results obtained from the evaluations of the analyses, it is possible to say that perlite (G3) offers more advantages than its alternatives in terms of many variables. However, according to the conclusive results, it has been understood that the use of a single type of substrate as plant growing media would not be sufficient to encourage the maximum performance of green roofs. To ensure that, considering the advantages of each substrate group, it is proposed that their combined use would be more beneficial.

In this study, the filtration performance of different geotextile materials was investigated based on the extensive roof garden model. The studies related to the research were carried out as an open field pot experiment in Ege University Bayindir Vocational School. Crassula ovata from succulent group plants was used as plant material. 3 filtration materials were tested as filter layers, namely glass fibre, raw cotton, and polypropylene fabric. Various statistical analyses were applied to determine the effectiveness of the filtration materials in extensive roof garden applications. According to statistical significance levels it can be said that the use of polypropylene fabric as filtration material would be more advanta-geous compared to alternative geotextile materials.

Daha etkili havalandırma sağlamak için, domates bitki sıraları Doğu - Batı yönünde oluşturulmuştur. Kısa kenara paralel, sera ortasındaki düşey bir kesit üzerine farklı yüksekliklerde yerleştirilen sıcaklık ve bağıl nem sensörleri ile, 30 dakika aralıklarla, sera içi sıcaklık, çiğlenme sıcaklığı ve bağıl nem değerleri ölçülmüş ve kaydedilmiştir. Elde edilen verilerden yararlanarak, düşey kesit üzerinde, günlük ortalama ve gece ortalama olarak, sıcaklık, çiğlenme sıcaklığı ve bağıl nem desenleri elde edilmiştir. Araştırmadan elde edilen sonuçlara göre, sera tabanından mahyaya yükseldikçe sıcaklıklar artmaktadır. Bu artış, gece daha düşüktür. Bitki yoğunluğunun fazla olduğu blok merkezlerinde bağıl nem daha yüksektir. Çiğlenme sıcaklığı değerlerine göre, bitki yoğunluğunun fazla olduğu yerlerden başlamak üzere, serada nem yoğunlaşması olmaktadır.; This research has been performed in a two-block-unheated glasshouse. Its dimensions are 24 m % 67 m. The greenhouse is constructed on a North to South axis. To enhance the efficiency of ventilation the plants have been planted East to West. Heat, dew point temperature and the relative humidity values are taken in 30 minutes intervals in the middle of the greenhouse with the sensors, which have been installed on the West - East vertical crosscut. By using the measured values, all of these measurements are obtained daily and hourly temperature and relative humidity graphs, interior temperature of the greenhouse, dew point temperature and the relative humidity designs. According to the results, the temperature increases from ground to ridge of the greenhouse. The increase is lower at night. The relative humidity is higher in the middle of the blocks where the plant intensity is much more.

Antikçağdan yirminci yüzyıla gelinceye kadar önemini koruyan Meles Deresi’nden yazarlar; ‘kutsal kabul edilen dere’ olarak bahsetmekte, Homeros’un adının Meles ile birlikte anıldığını bildirmektedir. Meles Deresi, seyyahların İzmir’e geldiklerinde uğramadan geçmediği, ticari yolların üzerinden yer aldığı bir dere olarak 19. yüzyılda önemini korumaya devam etmiştir. 20. yüzyıla gelindiğinde, hızlı kentleşmeden Meles Deresi’nin de etkilendiği, çevresini gecekondular ve sanayi binalarının kuşattığı, suyunun kirlendiği ve kanal içine alınarak dere görüntüsünden uzaklaştığı görülmektedir.; As the historical books on Izmir Province are studied, it is seen that & #8216; The River Meles& #8217; have been frequently mentioned. The river preserving its importance from Ancient Ages to the $20^{th}$ century, have been discussed by the writers as the & #8216; holy river& #8217; and the name Homers have been mentioned with the river. In the $19^{th}$ century, the River Meles preserved its importance as a river that the voyagers visited and the commercial accesses intersected. In the $20^{th}$ century, the river was overwhelmed by urbanization, surrounded by the squatter houses and the industrial buildings and its water has been polluted; besides, by being involved in a channel, it does not look like a stream.
