ASSESSMENT OF EFFECT ON INVESTMENT COST OF THE OPEN CHANNEL IRRIGATION SYSTEMS OF LAND CONSOLIDATION CASE STUDY OF DENIZLI PROVINCE, TURKEY

In this study, irrigated agricultural areas in Den-izli-Tavas-Kızılcabölük neighborhood were chosen as the research area. According to the situation of before and after the land consolidation, projects of open channel irrigation system have been prepared. According to the prices of 2014, the investment costs of the irrigation system for the state of before and after the land consolidation are compared. In the research, for entire irrigated area in the open channel irrigation system, it was determined that according to before land consolidation, density of irrigation network and channel length decreased around 18%, and road length and road network density increased approximately 72%. Additionally, it was determined that after land consolidation, the project estimate cost, facility cost and investment cost of open channel irrigation system decreased by 19.4% and the channel costs decreased by 19.7%. According to before land consolidation; it was determined that the total cost and average unit investment cost of the irrigation system decreased by 16.2% and about 14%, respectively. As can be seen from these results; land consolidation had positive effects in open channel irrigation systems in terms of the irrigation and road network densities, expropriation cost and investment cost.
