Step Procedure

1 Conduct geological study based on a thorough review of available data in-
cluding analysis of aerial photographs. Initiate preliminary subsur-
face explorations.

2 Analyze preliminary exploration data and from this analysis establish
preliminary soil profiles, borrow locations, and embankment sections.

3 Initiate final exploration to provide:

a. Additional information on soil profiles.
b. Undisturbed strengths of foundation materials.
c. More detailed information on borrow areas and other required
excavations.

.

4 Using the information obtained in Step 3:

a. Determine both embankment and fOWldation soil parameters and
refine~reliminary sections where needed, noting all possible
problem areas.
b. Compute rough quantities of suitable material and refine borrow
area locations.

5 Divide the entire levee into reaches of similar foundation conditions,
embankment height, and fill material and assign a typical trial
section to each reach.

6 Analyze each trial section as needed for:

a. Under seepage and through seepage.
b. Slope stability.
c. Settlement.

7 Design special treatment to preclude any problems as determined
from Step 6.

8 Based on the results of Step 7, establish final sections for each reach.

9 Compute final quantities needed; determine final borrow area locations.

10 Design embankment slope protection.
