  Irrigation networks are responsible for the distribution and delivery of agricultural water, so improving their performance reduces losses and increases the efficiency of water distribution, and thus leads to improved water efficiency. Investigating the operation of irrigation networks is essential for planning and improving irrigation networks and systems. The first purpose of the assessment is to determine the amount of losses that occur in the process of distribution and delivery of agricultural water in the network of irrigation canals. Losses in agricultural water conveyance and distribution systems occur for two main reasons: leakage and improper performance of canal structures that cause operating losses. Various factors such as weed growth in canals, accumulation of sediment in canals, accumulation of garbage in canals, cracking of canal cover, crushing or moving of concrete parts in canals, destruction due to poor quality of materials and lack of sufficient knowledge of total operation and the wisdom of the country's water decision-makers is increasing losses in agricultural distribution and delivery systems. Factors influencing the operation of networks include regular annual maintenance process and the operation of network operators to timely and correctly adjust the catchment structures to prevent unstable hydraulic conditions in the main and secondary channels, which can be invested in training operators and teams. Management and operation in irrigation networks significantly reduced the volume of operation losses. In this study, the results of studies on the determination of conveyance and distribution efficiencies in irrigation networks have been reviewed and summarized. Manuscript profile

  Eliminate deprivation and rural development, one of the programs on the agenda is the implementation of the rural master plan to provide equitable facilities through physical transformation of the village, creating facilities it has been social-productive, providing public services and improving the housing of the villagers. The effects of conductor designs are limited to changes in physical texture and less attention is paid to the economic factor in its implementation. The purpose of this study is to investigate the role of pilot projects in the development of physical development and identification of living space from the perspective of residents. This research is applied in terms of purpose and in terms of descriptive-analytical approach, which has been done with a sample of 250 people from rural areas in Rasht. Data collection tools in this study included: library studies to collect information related to research literature and then field research through observation and questionnaires. The statistical population of the study is the villagers living in the villages of Rasht city. In this study, the correlation method by Kiiging method has been used for physical identity. In other words, the data analysis method is based on spatial statistics. The results indicate that the pattern of spatial distribution of physical identity variables in the villages of Rasht city is linear (north-south), which means that the villages located in the south, center and north are in a more favorable situation.
