Currently Dr. Abdelazim Negm (the editor) is a Professor of Water Resources in Egypt-Japan University for Science and Technology, a research-oriented governmental university with Japanese partnership. He was the Vice-Dean for Academic and Student Affairs in Faculty of Engineering, Zagazig University during the period 2008-Dec.-2011.

Scour downstream irrigation and hydraulic structures is very dangerous because it can easily causes complete or at least partial failure of these structures if they are not designed to take to impact of scour into consideration. Sudden expanding stilling basins are used widely in irrigation canal systems downstream of weirs, regulators and barrages. Therefore, it is very important to predict the scour characteristics in these basins to enable a safe, efficient and economic design of sudden expanding stilling basins. Different techniques are used including dimensional analysis, experimental approach, visual analysis, statistical analysis and artificial neural network. The editor has a wide experience in the field of hydraulic engineering and water resources. He is the author of more than 170 scientific papers and several books in hydraulics. He has got many scientific prizes and awards. He supervised more than 20 MSc and PhD thesis. You should not miss the reading of this book
