I am looking for runoff data (ground or satellite) especially for Khartoum, Sennar, El Deim, Kessie and Bahir Dar stations during the period (2008-2018).
In large scale I think the data assimilation based on GLDAS is one of the best sources for runoff and other hydrological features. in the following link you can find more about GLDAS :
Moreover, you can use eartH2Observe in order to access several large scale and regional scale models that simulate runoff and other hydrological terms. I think it is more complete and comperhnsive than GLDAS. Try it..
Try the Sudan National Electricity Corporation and/or the Ministry of Agriculture. These are the sources I used in the 90's for complete and up to date streamflow records.
