Summary
The Handbook is published in three volumes. Volume I comprises Chapters 1 to 5. The types of small hydraulic structures available, and their importance for efficient distribution of irrigation water supplies are discussed in Chapter I. Chapter 2 discusses the operation of irrigation systems and how this governs the choice of the type of small hydraulic structure best suited to the purpose. Chapters 3 to 5 deal with small intake structures, small flow-dividing structures, and outlets or farm and field turnouts. Volume II comprises Chapters 6 and 7. Chapter 6 deals with small water-level and velocity control structures (i.e.checks or cross regulators, falls or drops, and chutes) and Chapter 7 with small hydraulic structures and devices useful for measuring flow in irrigation networks. Volume III, which will be issued at a later date, will cover small cross-drainage works, escapes and miscellaneous structures and will include a chapter on the detailed design of gates.(LB)
