(4) The second talus bed length (d ) was then plotted as shown

(5) This methodology was continued along the entire side until a 

 planar view of that side was constructed. 



(6) To show these data in three-dimensional diagram, the planar 

 diagram was converted to a series of triangles using d^ as the 

 hypotenus of the revetment and d^ as the hypotenus of the talus. 

 Depths (height) were converted to MLLW by adding or subtracting 

 the number of meters difference according to time (e.g., at 

 1330 hours, 15 October 19 76 tide at Rincon Island (Ventura) was 

 +0.76 meter; thus, 0.76 meter would be subtracted from the 

 height of the "revetment triangle").
