Foundations of river bridges need to be protected with respect to excessive scouring.
Degree of protection depends on the severity of scouring action around bridge piers
and abutments. A case study is carried out to design appropriate protective measures
for sequential viaducts located on Ankara-Pozant highway in Turkey. A number of
analyses are conducted to obtain water surface profiles throughout the study reach.
Local scour depths at piers and abutments of the viaducts are then obtained. The
design process for countermeasures is performed concerning hydraulic, hydrologic,
constructional, and economical requirements. To this end, riprap, partially grouted
riprap, and articulated concrete blocks are studied in these view points. A criterion
based on a selection index, which is defined by the National Cooperative Highway
Research Program in the USA, is applied in this study. Implementation of partially
grouted ripraps at infrastructural elements is found to be an appropriate solution.
