Efforts to increase the amount of irrigation schemes transferred to irrigation associations (IAs) in Turkey have been motivated by the poor performance in terms of cost recovery, equity, efficiency in operation and maintenance (O&M) and repairs of many large irrigation schemes by government agencies, namely the State Hydraulic Works (DSI). The objective of this study is to assess the irrigation system performance of transferred irrigation schemes in the DSI Fifth Regional Directorate service area mainly for the year 2003 with benchmarking indicators. According to the findings of the study, relative water supply was recorded as 1.5-8.4 respectively. The financial performance indicators including cost recovery ratio, maintenance expenditure to revenue ratio, operating cost per unit area, total cost per person employed on water delivery, revenue collection performance and service area per personnel were found to be 1.0-10.6%, 0.7-12.5%, US$6.5-53.3 ha(-1), US$636.0-7045.9 per person, 78-95%, 67-13 000 ha per person, respectively. As regards productive performance, output per unit command area, output per unit irrigated area, output per unit irrigation supply and output per unit water consumed were determined as US$325.2-2745.1, US$1028.03-5070.9 ha(-1), US$0.2-0.7 m(-3) and US$0.2-2.6 m(-3) respectively. Water quality classes were found to be C(3)S(1) in all schemes. The results of the case study show that following the transfer of irrigation schemes to the user organizations, significant improvements are recorded in irrigation water fee collection rates and financial cost reduction in the systems operated by the IAs. Mixed results are observed in terms of irrigation ratios. While there are improvements in two irrigation schemes, there are evident increases in the water supply ratio in six other irrigation schemes. Management, operation and maintenance (MOM) costs in general and the maintenance costs per se have increased compared to the collected water fees in the case-study irrigation schemes.

Simultaneous dissolution and uptake of nutrients in microalgal treatment of the secondarily treated digestate
Ulgudur, Nilufer; Bayramoğlu, Tuba Hande; Demirer, Goksel N. (Elsevier BV, 2019-11-01)
Anaerobic digestion processes result in large volumes of digestates which still require the development of elaborate and viable management options to improve the sustainability of these processes. Coupling of secondary anaerobic treatment with a microalgal nutrient removal process may serve benefits such as residual biogas and associated greenhouse gas capture from the digestate content, microalgal biomass build-up and its further valorization. This study investigated the applicability a microalgal nutrient...
Modeling of settlement in saturated and unsaturated municipal landfills
Durmusoglu, Ertan; Corapcioglu, M.Yavuz; Tuncay, Kağan (American Society of Civil Engineers (ASCE), 2006-07-01)
Municipal solid waste (MSW) landfills are not only used to dispose the refuse in most economical way but also utilized as a viable land in today’s waste management strategy. Settlement prediction is an important issue in order to guarantee the integrity of any postclosure structure on landfills. In this study, landfill settlement in saturated and unsaturated landfills is investigated by developing a one-dimensional mathematical model and performing numerical experiments. Under the saturated conditions, the ...
Application of the contingent valuation method in a developing country: a case study of the Yusufeli Dam in northeast Turkey
Alp, Emre; Yetiş, Ülkü (IWA Publishing, 2010-01-01)
Hydroelectric power plants and dams often play an important role in developing countries in terms of their contribution to economy. In accordance with the energy policies of Turkish Republic, Yusufeli Dam and Hydroelectric Power Plant in Northeastern Turkey have been initiated. In this study, the Contingent Valuation Method (CVM) was conducted in Yusufeli Village to determine the environmental costs of the Yusufeli Project. The purpose is to assess the willingness to pay (WTP) of Yusufeli Village residents ...
Estimation of wheat yields by using remotely sensed and modeled agro-meteorological data-driven statistical and crop growth models
Bulut, Burak; Yılmaz, Mustafa Tuğrul; Department of Civil Engineering (2021-6)
Estimation of wheat yield is essential not only for agricultural sectors but also for making economic and strategic decisions at the national level. In this thesis, wheat yield estimation was carried out on the cities and districts where the highest wheat production is made with rainfed agriculture in Turkey and on TİGEM research farms. Two different modeling approaches were evaluated within the scope of the thesis; a statistical multiple linear regression (MLR) model based on analysis of possible agro-mete...
Comparison of linear, labyrinth and piano key weirs to increase the discharge capacity of existing spillways for a given head /
Karaeren, Deniz; Bozkuş, Zafer; Department of Civil Engineering (2014)
Dams play an important role in infrastructure of our country and provide drinking water, flood protection, renewable hydroelectric power, navigation, and irrigation as well as facilities for sports activities. However, dams in Turkey are gradually aging and in order to assure the safety of those aging dams, rehabilitation is necessary. Very often, increasing the capacity of a spillway would be required in rehabilitation works. Thus, it is the main goal of this study to investigate some practical methods use...
