Abstract
Abstract A SYSTEM AND METHOD FOR PREVENTING EROSION OF AN EMBANKMENT WITH A SHALLOW EXCAVATION ABOUT NINE FEET IN WIDTH IS DUG IN THE GROUND ALONG THE TOP OF THE EMBANKMENT, SPACED SLIGHTLY BACK FROM THE EMBANKMENT EDGE. A TRENCH DEEPER THAN THE EXCAVATION IS DUG ALONG THE REARMOST SIDE OF THE EXCAVATIONREMOTE FROM THE EDGE OF THE EMBANKMENT. THE BOTTOM OF THE EXCAVATION IS SLOPED GENTLY IN THE DIRECTTION OF THE TRENCH AND A WATER IMPERVIOUS PLATIC SHEET IS LAID COVERING THE BOTTOM. DRAIN TILE IS PLACED IN THE BOTTOM OF THE TRENCH AND COVERED WITH GRANULAR MATERIAL SUCH AS CRUSHED STONE. THE EXCAVATION AND TRENCH ARE THEN COVERED WITH TOPSOIL. WATER SOAKING INTO THE SOIL CLOSE TO THE EMBANKMENT IS CAUSED BY THE PLASTIC SHEET TO DRAIN AWAY FROM THE EMBANKMENT EDGE AND IS COLLECTED BY THE TILE.
