Loss of structure and condition of the riparian zone

Changes to the physical characteristics of the river banks and bank top areas. Modifications such as bank protection, revetments and walls remove the natural structure of the riparian zone and replace it with artificial conditions with no morphological diversity and limited interest for ecological quality elements. Reprofiling of the banks through maintenance activity or land management practice (for example to increase cultivated areas) can result in removing the buffer zone allowing increase in volumes of fine sediment reaching the channel and reduction in bank stability, as well as direct loss of ecological value through reducing vegetation extent and diversity.
