Bank Protection Techniques Using Spur Dikes

摘要

A hydraulic model investigation was conducted to evaluate and demonstrate the effects of impermeable spur dikes as a bank protection technique in a concave bend. The tests were conducted to observe channel bed and bank response in a stream with noncohesive banks where suspended load is insignificant. Several parameters relative to spur dike design that were evaluated included: the length to spacing ratio, the orientation angle, and the effect of an apron or mattress of protection at the toe of the dike.
