Write a 8 pages paper on river engineering: appraising the options for river bank protection. Riverbank erosion is a common happening today as it has been witnessed in many shorelines where the soil is constantly washed up leading to soil erosion. Given that the work of engineers is to develop products to offer solutions to problems facing society, there has been the development of products and techniques that can actually strengthen the banks and mitigate soil erosion. Given that the work of engineers is to develop products to offer solutions to problems facing society, there has been the development of products and techniques that can actually strengthen the banks and mitigate soil erosion. Natural methods refer to the various methods of protecting the slope while the vertical methods refer to the development of structures extending to the channels of the stream to help by redirecting the flow of water. The engineering concept here is that as soon as the water has been redirected, the hydraulic forces at the boundary of the channel will be reduced to a level that cannot cause erosion.
Natural methods of protecting the slope fall into three major categories including self-adjusting armors, rigid armors, and flexible mattresses. The natural methods operate by “armoring” the surface of the bank making it hard for soil erosion to occur (WETLANDS ENGINEERING & HAYES, 2004). The natural method is also widely known to address problems related to overbank drainage. The major requirement with this method is geotechnical stability to aid in the proper placement of the designed armor. This in many cases is known to have caused the replacement of adjacent structures, increased environmental damage, and also comes at a relatively higher cost. It should also be noted that filling material will be used in the alignment of the existing channel.
1.1 Riprap Blanket: This is a designed blanket of stones that form a “crowd” resistant to movement. The stones are shaped in a way that they have sharp edges at their points of intersection.
