Wave action erodes some of the bank above the water <br /> level, and deposits sediments immediately below the water surface, resulting in a"bench" <br /> and irregularities in the slope (Figure 5). The intent of Rule 3.1.5(7) is to ensure bank <br /> stability. The resulting bench from the erosional process and vegetation of the slopes <br /> ' ensures that the bank remains stable. <br /> ' 20210727 SlopeEvaluation_DR.L1.S_RTC SFE.docx T E L E S T 0 <br />
