Over the last 15 years, traditional spate irrigation system was modernizing by different governmental and non-governmental projects. None of this modernized schemes were achieved their objectives and most of these was failed due to siltation and less spate flow. The main problem was adoption of designs parameter from normal irrigation system. Spate irrigation system is unique and different from other irrigation systems and needs special attention to develop appropriate design standards.

Produktbeschreibung
Over the last 15 years, traditional spate irrigation system was modernizing by different governmental and non-governmental projects. None of this modernized schemes were achieved their objectives and most of these was failed due to siltation and less spate flow. The main problem was adoption of designs parameter from normal irrigation system. Spate irrigation system is unique and different from other irrigation systems and needs special attention to develop appropriate design standards. This book, therefore, provides new design alternatives of spate irrigation to minimize sedimentation hazards and increase spate flow to the schemes. After detailed study of design development and their limitations four alternatives of design parameters were developed. These alternatives were analyzed using a software model of Delft3D and the best design alternative was recommended to implement on ground. The study should help shed some light on this new and exciting design standard, and should be especially useful to professionals and experts in the field spate irrigation engineering, or anyone else who may be wants to know about characteristics and challenges of spate irrigation systems.
