On 3 September 2015, the public defence and awarding ceremony of Ishraga Sir Elkhatim Osman will take place. The title of her thesis is: Impact of improved operation and maintenance on cohesive transport in Gezira Scheme, Sudan. Professor Bart Schultz will be her promotor. The co-promotors are Prof. dr. Akode Osman, University of Khartoum and Dr. F.X. Suryadi.
The book illustrates data collection and field measurement techniques in Gezira Scheme in Sudan.The sediment accumulation in irrigation canals represents a challenge to those responsible for the operation and maintenance of the canals. The properties of cohesive sediment, cohesive sediment processes and the factors that affect sediment transport are described. Ms. Osman presents a new numerical model for sediment transport. The model has been calibrated and validated with field data. The mechanisms of water and sediment flow under different operation and maintenance scenarios are discussed. Strategies for water management, which reduce the maintenance cost in irrigation canals, are presented.
