Impact of Silt Excluder on Sediment Management of an Irrigation Canal: A Case Study of D.G. Khan Canal, Pakistan

This study estimates the sediment transport capacity of D.G. Khan Canal and analyses the impact of silt excluder on the sediment management of the canal. The average sediment load entering into the D.G. Khan Canal before the silt excluder’s intervention was about 258 ppm which is 58% more than the sediment transport capacity of the canal (163 ppm). However, the post-intervention average sediment load observed during 2006–2009 was 183 ppm which indicates that the intervention of silt excluder has reduced the sediment entry in the canal.
