| Abstract | ||
| This paper describes the results of experimental investigation on flow behavior below hydraulic structures on pervious soil layers. The pressure acting on the bottom of the structure during under- flow and the quantity of seepage discharge were measured. The present paper provides more evidence, which support the previous work based on the difference of scour hole depth at the bottom, and at the soil surface behind the aprons. Laboratory experiments have been carried out to investigate, critical case of flow behavior below the hydraulic structures, the effect on the stability of the hydraulic structures, and identity the length of protection works. The pressure data were analyzed in detail as curves drawn for each depth of water level. It was noticed that maximum danger of scour lies at the exit of the hydraulic structures | ||
