A Sustainable Outlet for Canal Irrigation System

Abstract

The present work is first time observed based on a novel idea of irrigation modules. Keeping various points in mind like; outlet theme, its requirements and challenges in Indian canal irrigation systems, the author came to a novel solution to the farmers’ problems regarding under or over-irrigation of crops. It is an Indian approach towards rigid module. Primarily, the novel device is a combination of a masonry well-constructed in the bank of a parent channel connected with flow throughout the depth of flow in feeding minor and a flexible neck tube attached with a floating object maintaining a constant head with respect to a parent channel and this way it maintains the constant discharge supplied to the farmers even in varying head during rising and falling minors in the intermittent supply of water in Indian Canal Irrigation Systems. The device was validated through the experimental observations and the results were found very exciting within laboratory conditions. This will help a lot to the suffering farmers to get rid of their usual problem of non-uniform release of water from feeding channels. This device overcomes the problem of varying heads in parent channels during intermittent supply, provides equal discharge to the farmers on their turn. It is comparatively very cheap, easy to construct, repairable and not at all likely to be tampered by the powerful farmers. It can be maintained even by unskilled labour/farmers. The device meets all international requirements of ideal modules.
