Irrigated Areas Discharge and Sediment Interaction Case Study Roseires Dam

Résumé

Dams and reservoirs are constructed in rivers for multipurpose. Irrigation is always predominant. Irrigated agriculture in Sudan produces about 50 % of the total crop production. There is always painstaking in removing sediments from the irrigation network system. The objective of this study is to assess the relations among sediment irrigated areas and discharge in Roseires Dam Reservoir. Dimensional analysis and SPSS models, in both simple and multiple correlations were conducted. The simple correlation gave acceptable results with high correlation coefficients. Complete set of dimensionless groups were obtained in the multiple regression correlation. Examination of the results indicated good correlation with acceptable error.
