“…Numerous bathymetric surveys conducted worldwide have identified significant decreases in reservoir storage capacities (Rowan et al, 1995;Güvel et al, 2017;Darama et al, 2019;Shiferaw and Abebe, 2020;Ugwu et al, 2021;Güvel, 2021;Güvel et al, 2021b). Moreover, in recent years, researchers have increasingly utilized remote sensing data for bathymetry mapping and sedimentation assessment (Jagannathan and Krishnaveni, 2021; Skariah and Suriyakala, 2021).For instance, Taruya and Fuji (1997) conducted a study on reservoir sedimentation in irrigation dams in Japan, analyzing field data from 53 high dams.…”

In this study, sedimentation in the Seyhan Dam reservoir was investigated by analyzing a long-term bathymetric survey dataset. The focus was on understanding how reservoir capacity changes impact reservoir operation rules. The findings revealed that sedimentation from the main branch of the Seyhan River has largely stopped since the construction of the Çatalan Dam, but sedimentation from the Çakıt branch continues. Furthermore, the study observed changes in the upper basin between 1990 and 2018 based on the CORINE Land Cover (CLC) dataset. The forest area increased from 23.71% to 24.36%, and water bodies expanded from 0.3% to 0.9%. This increase in forest and water bodies contributed to a reduction in sediment flow into the Seyhan Dam reservoir. The researchers used regression analysis and found a high correlation (R2=0.96) between water storage capacity changes and time (in years) at a 67.5-meter water level in the Seyhan Dam Reservoir. Overall, the study's results suggest that the decrease in sediment entering from the main branch of the Seyhan River has significantly improved the sedimentation issue.

“…Sigorta, aynı risk tehdidi altındaki bir topluluğun ortaya çıkabilecek bir risk sonucunda doğabilecek hasarlara karşı birlikte karşı koymalarıdır. Sigortanın amacı; muhtemel hasarı önlemek değil, bu hasarı fertler arasında dağıtarak hasarın boyutunu grubun her üyesi için taşınabilir hale getirmektir (Güvel & Güvel, 2018;s. 28).…”

“…Modern anlamda ise; bir risk yönetim aracı olarak devreye girmekte ve bir dizi işlevler üstlenmektedir. İlgili temel işlevleri girişimciye güven sağlaması, girişimcinin yatırım kararlarını olumlu etkilemesi, atıl sermaye miktarını en aza indirgemesi, girişimcinin kredi bulmasını kolaylaştırması şeklinde özetlenebilmektedir (Güvel & Güvel, 2018;ss. 32-33).…”

Insurance protects individuals and assets against potential risks and their negative economic effects. In the current system, conventional insurance is a type of insurance that includes applications such as interest, gambling, and garar. Apart from these practices, the insurance system, which takes its source from Islamic principles, is participation insurance. In this study, general information about participation insurance is included and the relationship between participation insurance, economic growth, and consumer confidence index is discussed in Turkey in particular. The sample of the study consists of 50 observations covering the period 2009Q4– 2022Q1. In the study, the causality relationship between the variables related to participation insurance was investigated by VAR analysis and Granger Causality Test. According to the findings obtained because of the analysis, while there is a two-way causality relationship between participation insurance operating in Turkey and economic growth, no causality relationship was found with the consumer confidence index. The results of the study are in line with theoretical studies and coincide with the results of previous empirical studies. In this context, since the growth of participation insurance will mean the growth of the country's economy, it is expected that the public authority will play a greater role in the planned growth of the sector.

“…As regards to its importance on dam operation and recent developments on GIS technology, many studies were conducted on bathymetric assessment of reservoir sedimentation. Reservoir sedimentation was investigated in Seyhan Dam reservoir (Güvel and Yurtal, 2020), in Berdan Dam reservoir (Güvel at al., 2017), in Aswan High Dam reservoir (El-Sersawy, 2005). The level-areavolume relation was calculated by using bathymetric measurements in the Ruiru reservoir (Sang et al, 2017).…”

The determination of the volume of water to be stored is one of the most important criteria for dam and pond planning and operation. This amount is calculated locally prior to planning studies, and a bathymetric map is created following water storage in the reservoir. Because of sedimentation during the operation period, the volume of the reservoir decreases over time, and this situation appears as a problem in the operation of the water structure. In this study, the reservoir storage volume changes and reservoir sediment accumulation rates between the locally produced map before the construction of Tahtaköprü Dam and the hydrographic survey maps prepared during operation period were investigated by using GIS modules. It was determined that the decrease in the storage volume of the dam reservoir at the maximum water level by 9.15% and at the minimum water level by 51.90% was due to sediment accumulation. The effect of the changes in the land cover and forest area in the basin on reservoir sedimentation was examined and it was found that land cover and forest area in the basin have reduced sediment accumulation in the reservoir. Furthermore, sediment thickness change was mapped to compare the decrease in the storage volume capacity of the reservoir at the maximum water level and at the minimum water level by comparing the digital elevation models of 1962, 1980 and 2014 to support the decision-makers on determining reservoir operation rules in order to benefit water resources effectively within the scope of sustainable management of water resources.
