    Development of Water Resources and Agricultural Practices under Irrigation in Thrace Region: Analysis of Existing Data for the Solution of Problems
    (Univ Namik Kemal, 2006) Istanbulluoglu, A.; Konukcu, F.; Kocaman, I.
    Although Turkiye, particularly Thrace Region, seems to be rich in soil and water resources in comparison to its location, population growth, pollution caused by industrialisation and possible global warming threaten the high potential cultivated lands and important water resources and shadows food security and economical development. Shortages in these resources are not only inevitable for all sectors but also affect profoundly irrigated agriculture which has an important place in the country's stability. In this research, soil and water resources potential of Thrace Region located in the European part of Turkiye were investigated, problems in relation to the use of water resources for irrigation in the regional base were evaluated, practical solution to the existing problems were suggested analysing the available data thoroughly. Problems and solution were categorised into three: problems related to the use of available resources wisely, problems encountered during the application of water, problems faced during operations. Initiating works to improve water resources before being late, producing scientific projects and supporting them with priority were particularly emphasised to overcome inevitable future water crisis in the region.

    Research on the sedimentation and erosion problem of the Ergene River Basin in Western Turkey and precautions to control it
    (Maik Nauka/Interperiodica/Springer, 2007) Kocaman, I.; Konukcu, F.; Istanbulluoglu, A.
    The objective of this study was to asses the rainfall-runoff-sedimentation relationship from directly measured data since 1972, to find out the effect of the present land use and soil cultivation techniques on the sediment yield, and to offer practical solutions to the problems in the Ergene River Basins located in the European Part of Turkey. The suspended sediment yield was calculated by multiplying the daily average discharged water by the average sediment concentration, while the eroded coarse sediment yield was computed using a regression equation developed by the Japanese Ministry of Construction. The relationship between the runoff and suspended sediment rates was explained exponentially as S = 1.99 Q(A)(1.62) (P > 0.01 and R(2) = 0.846) (S is the suspended sediment rate in t d(-1), and Q(A) is the average daily runoff rate in m(3) s(-1)). The suspended sediment rates of the Ergene Basin can then be predicted from the flow rate at any time of the year using this produced regression equation. According to the results, 70% of the basin's soil (9534 km(2) and occupying 81.76% of the total area of the region) is under erosion hazard varying in intensity, namely, 25.3% light, 34.6% moderate, 8.6% strong, and 1.5% very strong. 47.09% of the average 604 mm precipitation falls in the critical period of October-January in terms of the sedimentation. The coarse and suspended sediment yield was 74.040 t km(-2) per year, which was well below the average for Turkey. However, it was 2 and 2.5 times larger than the average for Europe and Africa, respectively. Because 76.93% of the eroded land is in the 1rst, 2nd, and 3rd class, the severity of the sedimentation situation is proved. The causes of the high sediment yield were identified, and a series of precautions were suggested to minimize them.

    A Study on Physical and Mechanical Properties of Bricks Produced and Commonly Used in Agricultural Buildings around Tekirdag
    (Univ Namik Kemal, 2006) Sisman, C. B.; Kocaman, I.; Gezer, E.
    The objectives of this study were to investigate the physical and mechanical properties of raw materials and bricks produced around Tekirdag and their suitability to the standards and to suggest guidelines to improve the quality. Soil samples used in bricks production and brick samples were collected from six factories working in order at the present. As a result of the test on these samples, it was investigated that Ferhat and Has brick factories used comparatively fine materials while Tolga brick factory used loamy materials. The thicknesses of all products of the factories were lower than 0,76 cm, which was considered to be quite low according to the Standards. As a result of the test on the sample bricks, average pressure resistant of the samples were between 24,21-38,20 kg/cm(2). All products of the factories except Tolga were found to satisfy the standards in the aspect of pressure resistance. As fort he bulk density, critical lime and magnesium rates, brick samples of all factories were suitable. Bricks of Has and Ferhat factories were not suitable in the aspect of freezing resistance.
