Longitudinal peak stone toe protection
WebAmong the dozens of techniques described in the Toolbox are longitudinal peaked stone toe protection, j-hook vanes, rock arch rapids, oxbows, riparian corridor restorations, and tree/shrub plantings. Web6. Design of Toe Protection. Adequate toe protection should be included in the design to prevent sliding failures, scour and undermining at the base of a seawall. Both revetments and seawalls should also be adequately set into the underlying strata. For armor stone revetments it is common practice to specify that stone at the upper end of the
