b. Temporary protection of potential overflow slopes and fill sections subject to erosion and sloughing can
be provided by placement of an armor of heavy weight material, not easily displaced by floodwaters, such
as large-sized stone (riprap) or sandbags. In blanketing the slopes, it is critical that the toe be adequately
protected to minimize the risk of base scour and possible embankment failure. Raising the roadbed
shoulder with riprap and sandbags can also be a suitable means for temporary relief.
