| dc.description.abstract | Performance evaluation of irrigation system is essential to assess how far the goals and objectives set forth at the time of project formulation of the system have been achieved. Efficient operation and management for small scale irrigation system plays an important role in the sustainability of irrigated agriculture. Nowadays, non-uniform water distribution among upstream and downstream users, structural failure, sedimentation and growing of weeds are the characteristics of Golina small-scale irrigation scheme. This study was initiated to evaluate the performance of Golina small-scale irrigation scheme using efficiency indicator, maintenance indicator and farmers perception. Primary data (discharge measurements in the canals, measurement of water applied to the farmers’ field, field observations, interviewing beneficiary farmers, and determination of moisture contents of the soil before and after irrigation, determination of soil physical properties) and secondary data like design document and number of farmers were collected to conduct this study. This study was conducted for one irrigation season (February-May). The collected data were analyzed using empirical equations and statistical analysis in percentage basis. The application efficiency result on three sample plots in farmers’ field located at Head, middle and tail reaches of the command area were found to be 46.30%, 65.87% and 76.07% respectively. Based on the maintenance indicator analysis, the main canal transports 82% of its design capacity. The effectiveness of infrastructures is found that 38.36% of initially installed structures were nonfunctional. The sustainability of irrigated area of the scheme was decreased by 35.14% compared with the planned area. Based on the assessment of farmer’s perception about the performance of the irrigation scheme, the respondents believe that major problems that make the scheme to be inefficient were maintenance problem, water theft or unauthorized canal breaching in the scheme, water shortage and water utilization conflict and they have low level of ownership of the scheme. Generally the overall performance of the scheme is considered as poor. So, it is important to strength water user association, provide hydraulic flow measurements, routine maintenance and creating awareness for the users to achieve good performance of the scheme. | en_US |
