Abstract




ABSTRACT
The main aim of this research is to get a control of scouring around the abutmen of bridge. Scour
around the abutments must be controlled because it is the main damage cause of abutments and
the hydraulic structures built in the river bed. This research was carried out using expermental
method by standart teaching flume and steady-uniform flow in Hydraulic Laboratory Civil
Department Yogyakarta State University.. The research is done in clear-water-Scour The abutment
model were spillthrough type, wing-wall type, triangular type and semi circular type.The research
result shows that the good performance of maximum scour depth around the abutment ocurred at
wingwall abutment for 4b lenght is equal to 11 cm.
Keywords : Scouring, Groundsill, Wingwall abutment
