| Abstract | The effectiveness of resources devoted in Asia is an important concern that has attracted considerable attention. Gate operation is one of the major and important activities affecting equitable distribution of irrigation water. Conflicting and competing objectives are the major reasons hindering the formulation and implementation of effective set of gate operation rules. So a set of rules reflecting the society's objectives and capable of establishing tradeoffs among such objectives is highly desired. This study is conducted in a medium scale project of Nepal with an aim to establish such rules by analyzing the factors contributing deficiency in performance of irrigation. Analysis is based on simple methodology of field measurement and survey associated with simple statistics. The Khageri Irrigation System is a good example of the diversion systems based on the varying flow of the river. As usual the system is suffering from unreliable flow during high water requirement. This has led the increased demand of frequent and efficient control gate adjustment. Because of conflicting goals to be met at a time such as water-level management and discharge based management, operators get confused and are bound to form their own rules to satisfy the users which is not possible, as a result of which a clear inequity in distribution is found. Equity in distribution is not always the equal distribution of resources but most of times it is share of feelings. So social aspect as well as technical aspects both are discussed as far as practicable. From the analysis it has been noted that gate operation for equal distribution depends over several factors such as: Planning and Design of Control Structures, Communication and Information Transfer Procedure, Planning of Distribution Schedule, Skill of Monitor and Operator and above all Social Understanding. Since all above mentioned factors are associated with cost, low cost recommendations with simple modification in the existing rules are made for better performance. There are several other indirect factors such as soil conditions and cropping pattern influencing the validity of rules, which can be considered as a subject of further research. |
