الملخص

The irrigated sector has vital contributions into food security and gross domestic product in Sudan. Among major problems, facing the irrigated sector is the sediment and aquatic weed removal. The most problematic aquatic weed in Sudan is water hyacinth, a native plant of South America that has been officially declared as an invasive pest since 1958. Water hyacinth forms dense plant mats, infested about 1700 km of the White Nile, from its upper reach near Juba to El-duim (70 km south of Khartoum) causing unenthusiastic collision on water intake channels. Its control measures depend initially on large-scale applications of chemicals. The main goal of this study was to investigate the impact of aquatic weeds on the performance of the irrigation network of the Kenana Sugar Scheme, White Nile State, Sudan, with special reference to the inlet channel of the pump stations. The specific objective of this study is to avert water hyacinth entering the inlet channel of the pump stations. Field and desktop datasets were collected for two seasons (2009/2010 and 2010/2011). The inlet channel was being divided into 5 cross- sections of 25 m in length per each. The water level was found to be 9% lesser the design one due to aquatic weeds. The results showed the detrimental impacts of aquatic weeds on the performance of the irrigation network, causing severe silt deposition and bank erosion and coupled with high maintenance cost of Kenana pumps stations. In the season 2010/2011, the cost of aquatic weed and sediment removal from the inlet channel, and all canals using mainly dredger, was found to be 1.856 million SDG, While the total cost of maintenance in Kenana pumps stations due the impact of aquatic weed is 0.357 million SDG coupled with civil work cost in Kenana inlet and canals due the impact of aquatic weed of 0.459 million SDG. The study recommended the need for fix suitable Tuff boom with debris screens permanently stretched across the intake channel for preventing the weed entering the inlet channel. Also, there is an urgent need for in-depth study on the impacts of weeds on the performance of the irrigation network.
