EXECUTIVE SUMMARY
Introduction about what this manual is covering concentrating on Large-scale Irrigation (LSI), diversion barrage or weir intake (with auxiliary structures), and most common conveyance structures suitable for LSI.
- A very brief overview of an approach to match water needs with water availability (demand vs supply) With references and links to FAO literature that is covering the topic in detail
- brief reference to the most common methods to obtain necessary hydrological parameters for irrigation scheme design.
- A very brief overview of the importance of knowledge of geological conditions and the investigation needed to obtain geotechnical design parameters (including most common geotechnical tests to obtain design parameters).
- Planning phase considerations regarding diversion and intake structure, discussing the role of the main components.
- More technical discussion on each component of weir or intake, including formula and worked examples (hydraulic and structural computations).
- Conceptual, hydraulic and structural considerations of main conveyance components, with emphasis and more detail on most used components (such as canals, siphon, agueduct, retaining walls etc.).
- A very brief overview of the approach to irrigation water management and operations & maintenance (O&M) with references and links to FAQ literature that is covering the topic in detail
- Standard specification for irrigation construction material.
