In fault zones, it is possible to encounter face and ceiling stability problems encountered during the tunnel excavation in the short term and failures in the support systems due to squeezing in the long term. For this reason, when designing support systems, short-term and long-term parameters should be considered. The most important factors in selecting the support system to be installed are to describe the geological conditions well and the correct selection of geotechnical design parameters.

This study aims to present the preliminary results of a study to determine the impact of climate change on river flow to develop sustainable watershed management plans and to evaluate the possible urban water use and environmental impacts to prepare policies to mitigate its negative impacts. In this study, the Soil and Water Assessment Tool (SWAT) was used as a hydrological model to predict hydrological effects of climate change to better understand and solve future water resource problems. In this context, firstly the Soil and Water Assessment Tool (SWAT) was operated on the Yuvacık Dam Basin in Marmara Region to reveal the present hydrological situation. The hydrological model was then simulated by using the climate change data that have 20 km spatial resolution between 2021-2099 years based on RCP 4.5 and RCP 8.5 scenarios that were produced by the General Directorate of Meteorology. Thus, the effects of climate change on the amount of water and sediment were estimated between these years. According to the RCP 4.5 and RCP 8.5 scenarios, 2.23% and 2.062% decrease in the average annual rainfall, and 1.24 and 0.03 of increase in temperature values were predicted, respectively. However, an increase in precipitation was expected between April and August. The average monthly flows (between 2006-2014) of the Kazandere, Kirazdere and Serindere rivers recharging the Yuvacık Dam in the basin is 0.55, 1.28 and 1.94 m3/s, respectively. Corresponding modelled flow values based on RCP 4.5 and RCP 8.5 scenarios for 2021-2099 period, for Kazandere, Kirazdere and Serindere are 0.14 and 0.17 m3/s, 0.41 and 0.33 m3/s, 0.86 and 0.68 m3/s, respectively. These values show significant decrease in flow rates of the rivers in the future. Moreover, the peak flow values of the streams especially for Kazandere and Kirazdere decrease from 8 to 2 m3/sec. The amount of the monthly average of sediment measured at the Serindere stream station for the years 2010-2013 was 49 tons, while it was calculated as 247.58 tons based on RCP 4.5 and 332.21 tons based on RCP 8.5 for 2021-2099 period. According to both scenarios, an increase in the predicted rainfall between April and August, and an increase in temperature will cause mechanical erosion in the basin. Thus, the amount of sediment carried by flow is expected to increase. The Yuvacık Dam is used for providing irrigation and drinking water requirements of Sakarya and Izmit provinces, and for the prevention of flood as well as for water management during drought periods. Therefore, the decrease in the flow rates of the streams recharging the dam will cause a decrease in the water volume of the dam, hence the future water management planning should be made for the crop pattern in the irrigated areas of the dam and for the drinking water usage.

One of the most frequently used types of these rail systems is the light rail systems (LRS). The routes of the LRS are generally preferred on the existing road route. This situation creates some problems in terms of ground conditions. Since the rail system vehicle weights and passenger capacities are much more than road vehicles, the loads they apply to the ground are also higher. However, deformations occurring on the road surface generally affect vehicles and passengers in terms of comfort, while small deformations on rail systems can bring major problems such as accidents and deaths. For this purpose, it is very important to investigate the ground structure of the rail system route and to analyze the suitability situation in order to prevent these problems. In this study, the suitability of the LRS route planned to be built in the city center of Erzurum in terms of physical properties of soil was analyzed. In the analysis, it was suggested that some locations were problematic in the results obtained by using the basic rotary Erzurum İli Hafif Raylı Sistem Güzergahının Zemin Emniyeti Açısından Yeterliliğinin Araştırılması Investigation of Adequacy of Light Rail Systems Route in Erzurum Province in Terms of Ground Safety Ömer Lütfü AYDIN1 , Emre KUŞKAPAN2* , Muhammed Yasin ÇODUR2 1 Erzurum Büyükşehir Belediyesi, Muratpaşa Mah.

The toppling failures observed in the 670-pillar ́s slopes threatened the safety of excavation works for coal production in the open pit. The maximum runout distances of rock fragments that had toppled, fallen and rolled at different slope heights as a result of the mentioned mass movements were determined using computer softwares. The project excavation limit for the open pit coal mine was determined by considering the runout distances calculated for different slope heights.
