Evaluation of sediment transport in kirkuk irrigation channel

Abstract EN

In this research, the sediments transport and how to compute their amount have been studied in Kirkuk irrigation channel.

Empirical methods for computing sediments discharge in the channel have been discussed emphasizing on six methods (Blench, Graf, Larsen, Yang, Inglis-Lasey and Engelurd–Hansen).

The applications of these methods required the selection of (24) sections along the channel in order to measure the hydraulic parameters of the different cross sections in addition to the slope along the channel.

Samples of water sediments have been taken at each section in addition to bed samples.

The research introduces an equation for computing sediment load in Kirkuk irrigation channel depending on the data of (14) sections in the channel using statistic-MS program.

The validity of this equation has been verified with the application to the remaining (10) sections data in the channel and the results are very close to the field measurements.
