Evaluating the utility obtained by using radar based precipitation for prediction of flood events in western Black Sea basins of Turkey

Climate change has a direct influence on the hydrological cycle and its elements. Consequently, extreme events are expected to occur more frequently at different times and locations on the Earth and become more catastrophic.Hence, it is critically important to develop systems to accurately forecast rising water levels of streams and rivers prior to occurrence of dangerous conditions. Real-time flood forecasting systems are becoming a critical tool for emergency preparedness and decision making. Given radar observations may provide high spatial and temporal resolution precipitation information, these observations are commonly used to estimate precipitation for short-term period (1-2 h) and to monitor the track and extent of the precipitation events. Therefore, their use in flood prediction becomes very critical. With the aim of developing a fully coupled atmosphere-hydrology model system, the Weather Research and Forecasting (WRF) model is enhanced by integrating a new set of hydrologic physics parameterizations (WRF-Hydro) accounting for lateral water flow occurring at the land surface. In addition to precipitation input derived from WRF, in simulating flood events with one-way coupled system, radar-derived precipitation will also be used as input to the modeling system. The performance of the modeling systems will be evaluated for the selected heavy rainfall events and associated flooding conditions over Western Black Sea basins in Turkey. Radar based precipitation information is expected to improve the accuracy of the flood simulations.

Assessing the impact of climate change on Mogan and Eymir Lakes' levels in Central Turkey
Yagbasan, Ozlem; Yazıcıgil, Hasan (2012-05-01)
Global warming is likely to have significant effect on the hydrological cycle. Some parts of the world may see significant reductions in precipitation or major alterations in the timing of wet and dry seasons. Climate change is one of the serious pressures facing water resources and their management over the next few years and decades. As part of the southern belt of Mediterranean Europe, Turkey is highly vulnerable to anticipated climate change impacts. The changes in global climate will seriously affect i...
Estimation of diffuse solar irradiation and its effects on PV power plant production at METU NCC
Kavas, Genco; Taylan, Onur; Sustainable Environment and Energy Systems (2019-8)
Excess amount of greenhouse gas (GHG) emission is the main reason of global warming. Renewable energy systems are one possible way to decrease GHG emission and solar energy is one of options; however, fluctuations on solar energy production is one of the main drawbacks. Accurate estimation of energy production from a solar power plant, such as PV-based plant is important to satisfy energy demand successfully. To be able to estimate energy production in advance, solar energy incident on PV modules should be ...
Modeling of enhanced coalbed methane recovery from Amasra coalbed in Zonguldak coal basin
Sınayuç, Çağlar; Gümrah, Fevzi; Department of Petroleum and Natural Gas Engineering (2007)
The increased level of greenhouse gases due to human activity is the main factor for climate change. CO2 is the main constitute among these gases. Subsurface storage of CO2 in geological systems such as coal reservoirs is considered as one of the promising perspectives. Coal can be safely and effectively utilized to both store CO2 and recover CH4. By injecting CO2 into the coal beds, methane is released with CO2 adsorption in the coal matrix and this process is known as enhanced coal bed methane recovery (E...
Analysis of teleconnection patterns on climate of Northern Cyprus
Nabango, Hope Nabwire; Akıntuğ, Bertuğ; Sustainable Environment and Energy Systems (2019-9)
The complex interaction of components in the climate system has greatly contributed to uncertainty in climate patterns. Inarguably, anthropogenic factors have relentlessly increased this phenomenon. While innumerable research aimed at forecasting these interactions and their impacts on climate identify three streams of uncertainties as; model responses, external forcing factors and internal atmospheric variability, lack of knowledge on these factors have continue to challenge efficient results pertaining to...
Generation of monthly precipitation series and the performance of homogeneity tests
Akça, Elif; Yozgatlıgil, Ceylan; Yazıcı, Ceyda (null; 2016-08-26)
Climate studies have gained importance due to the significant effect of climate change. The extreme meteorological events can cause floods, droughts, sudden change in the temperature or change in the climate trends. Since they have an important effect on human beings and the environment, these meteorological variables should be predicted and some precautions should be taken if possible. In order to conduct any kind of statistical analysis, the nonclimatic effects should be determined and corrected or remov...
