An erosion in- ,jity scale—sort of a layman's guide to reading shore—is being developed to help people on t coast predict the erosion of specific areas and |,„ for the future. Riggs, Bellis and O'Connor ,pe to be able to impart enough knowledge about :osion to let coastal residents work with an under- jndingof the shores. Different rates for different banks Riggs, O'Connor and Bellis have already dis- jvered that different shorelines experience differ- Dt rates of erosion and they have identified some ujor shoreline types. The sand and clay banks ,clude low banks of one to five feet which are loderately to highly susceptible to erosion but can t protected fairly easily. High banks of five to 20 et may be extremely erosion-resistant if they're lade of tight clay or iron-cemented sand. If they're Dt, the high banks are subject to the same sort of osion as low banks. Bluffs rise higher than 20 Et and erode somewhat more slowly. They lose lore material per foot, though, and are very diffi- ilt to protect. Swamp forests have negligible erosion and sedi- ent berms are actually accreting. The area be- leen swamp forests and low banks erodes less lan the low banks but more than the forest. The ass marshes with their soggy peats are the most odable but they protect the sandy soils behind lem. Erosion of these shores is affected by numerous her factors, which the researchers are still trying unravel. So f
