| Note générale : |
In general, irrigation canals and the canals carrying water for municipal or industrial use have a smaller capacity to transport sediment than their river source of supply. The major reasons for this are the flatter bed slopes and relatively smaller flow rates of the canal. Thus, unless prevented from entering the canal with the diversion water by excluder sytems or removed from the canal near the head works by ejection systems, the sediment will be deposited, reducing canal capacity and making frequent costly cleaning necessary. This thesis discusses the various exclusion and ejection techniques, the essential sediment and river mechanics concepts needed for the design of successful systems and presents general guidelines for their design. |
