Riprap

Jun 29, 2021

A primary consideration in the design of stable riprap bank protection schemes is the slope of the channel bank. For riprap installations, normally the maximum recommended face slope is 1V:2H. 7.9.3 Rock Size The stability of a particular riprap particle is a function of its size, expressed either in terms of its weight or equivalent diameter

    RipRap is an effective way to provide additional protection to other coastal defence structures, and to man-made features such as harbour walls and pipes discharging into the sea. The rocks reduce the power of the waves hitting the structure and also disguise obviously man-made structures, help them to blend into the natural environment
