Minimizing scour downstream of hydraulic structures using single line of floor water jets

(in lingua inglese)

To improve the safety of heading-up structures, a system of single line of floor water jets is suggested and provided to reduce the scour problem downstream of new designed or existing structures. The suggested system is easy to be used as appurtenances. Based on the results of experimental studies, the following conclusions have been drawn, which are valid for the range of the obtained experimental data: the suggested system reduced the maximum scour depth as well as the scour hole length and moved the location of maximum scour depth closer to the floor.
