scour depth of -10 ft mlt. The 200- to 2,000-lb toe stone experienced a 

 significant increase in movement at the -10-ft depth; therefore, the 200- 

 to 4,000-lb stone tested on Plans 8, 8R, 9, and 9R is recommended for 

 prototype use. 



/. Plan 8 appears to be the best plan in terms of stability relative to 

 material sizes/amounts.
