“…These types of management reforms, that is, transfer of management from government to users, lead to success of these systems and were usually recommended for improving the performance of irrigation systems having low performance (Meinzen-Dick, 1997;Murray-Rust & Svendsen, 2001;Renault, 2001;Sam-Amoah & Gowing, 2001;Yercan, 2003). It has been found that due to better rules and fairness, leading to equity and transparency that has been implemented by users themselves, FMIS ought to succeed compared to AMIS (Trawick, 2001;Tanaka & Sato, 2003).…”

“…Reduced efficiency of irrigation systems were of major concern to the policy makers. Since water has become scarce, re-engineering the process of irrigation water management by introducing a more service-oriented management is one of the solutions (Renault, 2001). Management reforms were considered to be the best policy to prevent further deterioration of already sinking irrigation systems.…”

Management reforms are considered one of the best alternatives in increasing efficiency of the irrigation systems. Transfer of day-to-day operation and maintenance to farmers is not a new concept. However due to lags, even now it is a hot issue in developing countries and Nepal is not an exception. In this context of growing argument about the transfer of management of public irrigation systems to the Water Users' Group, this paper examines the comparative performance of farmer-managed and agency-managed irrigation systems. Khageri Irrigation System in the Chitwan district of Nepal was taken as the study site where complete management transfer has been done in 1996. The situations before and after complete transfer were compared. Intensive case studies of the selected farmers showed that equity in distribution of water and leakage had significantly improved after management transfer. Logit analysis revealed that age and education level of the household head, distance from main canal, leakage of the canal and equity in distribution are significantly related to the satisfaction level of the beneficiary farmers from FMIS compared to AMIS. However, landholding size of the respondent farmer has no significant effect. Similarly results from t-test revealed that rice productivity and overall profits from agriculture has also increased significantly due to irrigation management transfer.

“…Steady state hydraulics is the more generally understood and developed topic. Steadystate flow conditions have been a widely used design assumption in most gated canal irrigation systems and are canal operation targets (Plusquellec et al, 1994;Renault, 2001;Kouchakzadeh and Montazar, 2005;Renault et al, 2007). However, they rarely happen in common irrigation practice as a canal operation upstream (e.g.…”

“…More often, new changes in flow conditions as a result of the succeeding operation are already beginning to be reflected downstream just when the flow conditions are converging after the preceding operational procedure (Renault et al, 2007). Thus, the steady-state approach has limited practical significance for efficient management of canal irrigation systems, while it is not capable of analyzing the propagation of flow variations in discharge and water level along the canal networks (Renault, 2001;Kouchakzadeh and Montazar, 2005). Nevertheless, knowledge on steady-state flow properties of a canal system is relevant for purposes of measuring, monitoring and managing discharges at different locations along the canal network.…”

“…Unsteady flow condition is a norm in canal irrigation systems (Plusquellec et al, 1994;Renault, 2001;Plusquellec, 2002;Renault et al, 2007;Facon et al, 2008). Therefore, the unsteady flow approach is suitable for analyzing the flow dynamics of irrigation distribution systems and canal operation (Renault, 2001;Renault et al, 2007).…”

An open channel irrigation system is a physical infrastructure composed of canal reaches and numerous structures such as offtakes and cross-regulators, which conveys, regulates and distributes water for irrigation purposes. Each structure is meant to transform an input variable into an output one, and the flexibility of the output with respect to input variations can be expressed by a structure sensitivity indicator. The sensitivity analysis approach, applied to irrigation systems, might be considered an intermediary approach between steady and unsteady flow conditions for describing the flow behavior of irrigation canals. In this paper a preliminary analytical framework is developed to address the sensitivity of irrigation distribution systems. The development of hydraulic sensitivity indicators at local and reach levels is presented first. Then, by incorporating the time parameter in the analysis, a method for estimating a reach-time response to a perturbation is proposed. Also, a case study to evaluate the applicability of sensitivity indicators in assessing flow behavior in an irrigation canal was carried out. The results indicate that the proposed approach is capable of predicting the time required for damping a perturbation with a specified condition and provides the users with sufficient information to improve the management of water distribution in an irrigation network.
